Xbox Details Every Major Achievement Ahead of the October 6 Launch, Including 5 Campaign Acts, Co-Op Goals and Massive Multiplayer Milestones
With the game scheduled to launch on October 6, 2026, Xbox has now published the full Achievement list, giving players an unusually detailed look at the game's campaign structure, Horde Siege progression and Versus requirements before launch.
The list contains a total of 41 Achievements worth 1,000 Gamerscore.
It provides more than just a checklist for completionists.
Several Achievement descriptions reveal that the campaign contains five acts, while others confirm a co-op campaign, hidden collectibles, secondary objectives and a major progression system for Horde Siege.
The list also shows that E-Day is designed as a long-term multiplayer game rather than a campaign-only experience.
Players will have opportunities to level multiple Horde Siege classes, unlock weapon modifications, survive dozens of missions and accumulate tens of thousands of kills.
There are also some deliberately playful challenges, including turning a Boomer into a target for a particularly brutal attack and performing a chainsaw execution against a Locust. (xbox.com)
The Campaign Has Five Acts
The Achievement list confirms a five-act campaign.
Several achievements unlock automatically through campaign progression.
Act-based achievements reference major story moments in:
- Act 1
- Act 2
- Act 3
- Act 4
- Act 5
That gives players a useful indication of the campaign's overall structure before release.
The campaign follows Marcus Fenix and Dominic Santiago during the first days of the Locust invasion.
This is an origin story set 14 years before the original Gears of War.
The focus is therefore not on a veteran Marcus who already understands the war.
Players experience the early chaos of Emergence Day, when humanity is suddenly confronted with an enemy emerging from underground.
The Achievement list reflects that escalating structure, with story milestones spread across all five acts. (xbox.com)
Co-Op Campaign Is Confirmed
One Achievement confirms that players can complete the entire campaign in co-op.
The requirement is to finish all acts on any difficulty while playing cooperatively.
That means the campaign is not being treated as a strictly solo experience.
Xbox has already confirmed that E-Day supports two-player split-screen co-op on console and up to four-player online campaign co-op.
The Achievement system now gives completionists an additional reason to play through the story with friends.
This also reinforces one of Gears' most important traditions.
The series has historically been built around cooperative combat, and E-Day continues that philosophy rather than moving away from it. (xbox.com)
Collectibles and Secondary Objectives Return
The Achievement list also reveals that the campaign is not simply a straight path from one firefight to another.
Players can discover collectibles and complete secondary objectives.
One Achievement requires finding all collectibles in the campaign.
Another requires completing all secondary objectives.
This gives the campaign additional exploration goals for players who want to fully complete each section.
Xbox has also confirmed the return of a more structured mission design, meaning players can expect optional objectives alongside the main story.
For completionists, this means simply finishing every act will not be enough to earn everything.
Players will have to explore the environments carefully.
Hard Cases Add Another Collectible Hunt
One of the more interesting achievements requires players to discover all Hard Cases in the campaign.
The exact contents and locations of these cases are not fully detailed in the Achievement list.
However, their inclusion suggests that E-Day contains optional discoveries hidden throughout the game's environments.
That could encourage players to slow down during missions rather than constantly pushing forward.
Gears of War traditionally combines large combat arenas with environmental storytelling.
Hidden cases and collectibles can give those environments another function beyond combat.
It also creates a reason for completionists to replay chapters.
Horde Siege Gets a Huge Role
The Achievement list makes it clear that Horde Siege will be one of E-Day's most important multiplayer modes.
Horde Siege is described by Xbox as a reimagined version of Gears' iconic co-op PvE mode.
However, the new version is built around larger maps, more players and bigger battles.
Four-player squads can choose from several specialized classes:
- Assault
- Breacher
- Marksman
- Medic
The Achievement requirements reveal that players are expected to invest significant time in these roles.
One challenge requires reaching maximum level with all four classes.
That means players will need to understand multiple playstyles rather than simply mastering a single class.
You Need to Survive 50 Horde Siege Missions
One Achievement requires players to complete and survive 50 Horde Siege missions on at least Infantry difficulty.
This is one of the clearest signs that E-Day's PvE multiplayer is designed as a major long-term activity.
Fifty successful missions is not something most players will complete casually during a weekend.
It suggests that the developers expect Horde Siege to remain active well after launch.
The mode is also built around progression.
Players earn rewards, improve their loadouts and unlock additional options between matches.
The Achievement requirement therefore naturally aligns with the broader progression system.
Horde Siege Has Its Own Economy
Another Achievement requires players to spend 150,000 Energy at the Supply Cache in Horde Siege.
Energy is an important part of the mode's progression and resource management.
Players can use the Supply Cache to unlock equipment and upgrades.
The Achievement requirement suggests that successful Horde Siege runs will involve more than simply surviving enemy waves.
Teams will need to make decisions about how to use their resources.
Spend too much too early and the squad could struggle later.
Save too much and the team may miss opportunities to improve its defenses or equipment.
That resource loop should create additional strategic depth.
Invasion Events Become Another Horde Siege Challenge
Players also need to successfully complete 25 Invasion Events to earn another Achievement.
This indicates that Horde Siege will contain more than standard enemy waves.
Invasion Events appear to act as major encounters that interrupt or increase the normal combat flow.
That should make longer Horde Siege sessions more varied.
Instead of fighting identical waves repeatedly, players will have to react to larger threats and event-driven objectives.
The Achievement requirement also indicates that these encounters are expected to be common enough for dedicated players to encounter repeatedly.
Weapon Mods Are Part of Long-Term Progression
The full Achievement list confirms that Horde Siege includes Weapon Mods.
Players must unlock all of them to earn a dedicated Achievement.
This suggests that weapon customization will be an important part of E-Day's multiplayer progression.
The system can encourage players to experiment with different weapons and builds rather than relying entirely on default configurations.
Because Horde Siege contains different classes, weapon modifications could also interact with the strengths and weaknesses of particular roles.
The Marksman class might benefit from a different configuration than the Assault role, for example.
The exact depth will become clearer once the game launches.
Four Horde Siege Classes Have Different Roles
The four classes confirmed for Horde Siege give teams a clear structure.
Assault is designed around direct combat and aggressive engagements.
Breacher focuses on close-quarters pressure and heavy offensive tools.
Marksman provides long-range support.
Medic is responsible for keeping the team alive.
The Achievement requirement to max all four classes means that completionists cannot ignore less familiar roles.
That is likely deliberate.
Horde Siege is designed around cooperation, and a team composed entirely of the same playstyle may not be as effective as a balanced squad.
Versus Multiplayer Has Serious Grind Potential
Gears of War: E-Day's Achievement list also contains major Versus requirements.
One of the biggest requires players to achieve 25,000 kills in Versus.
That is an enormous number.
It is not designed as a casual challenge that most players will complete quickly.
Instead, it acts as a long-term milestone for highly active competitive players.
The Achievement list also reveals multiple skill-based challenges involving weapons, maps and specific enemy behaviors.
That suggests E-Day's Versus mode will reward both long-term dedication and experimentation.
Conquest Rewards Perfect Team Performance
One Achievement requires players to win a game of Conquest without the enemy team scoring.
This appears to be a more precise skill challenge.
It is not enough to win.
Players must completely shut down the opposition.
That means maintaining objective control and preventing the other team from building any score advantage.
Achievements like this can become popular among competitive communities because they reward coordinated team play rather than simple individual statistics.
Some Achievements Are Built Around Fun Challenges
Not every Achievement is about progression.
Several are clearly designed as memorable gameplay moments.
One challenge requires players to inspect the underside of a Raven in Horde Siege.
Another asks players to carve up a Boomer.
There is also an Achievement involving a chainsaw attack against a Locust.
Another requires using a Gut-Puncher round against two Grubs.
These challenges encourage players to experiment with equipment and environmental situations they might otherwise ignore.
They also continue the series' tradition of using humor and gruesome violence in its Achievement descriptions.
The Campaign Has Insane Difficulty Challenges
Completionists who want the hardest possible challenge have several requirements waiting.
One Achievement requires finishing all campaign acts on Insane difficulty.
Another combines a huge collection of campaign and multiplayer milestones into one final challenge.
The most demanding listed Achievement requires:
- Completing the campaign on Insane
- Completing all side missions
- Finding all hidden items
- Earning 25,000 Versus kills
- Reaching max player level
- Maxing four Horde Siege classes
That is essentially a full-game mastery test.
It will likely become one of the most difficult completionist achievements in the entire game.
The Ultimate 100 Percent Challenge
The most difficult achievement is worth 85 Gamerscore and is called “Dead Serious.”
Its requirements effectively ask the player to master every major component of E-Day.
The player must complete the campaign on Insane difficulty, reach 25,000 Versus kills, maximize their player level and max out four Horde Siege classes.
That is a massive commitment.
It also tells us something important about how The Coalition views the game's structure.
The campaign, Horde Siege and Versus are not separate side experiences.
They are designed to work together as the complete Gears of War: E-Day package.
The Achievement List Reveals More About the Game's Structure
Achievement lists can sometimes provide unexpected information before launch.
E-Day's list confirms a game that is divided into several interconnected layers.
Campaign provides the main Emergence Day narrative.
Horde Siege provides long-term cooperative PvE progression.
Versus offers competitive multiplayer.
And the Achievement system connects all three.
That is important because it suggests the game is not simply a traditional campaign followed by a small multiplayer mode.
The multiplayer systems are being built as substantial parts of the release.
The Campaign Includes Hidden Content
The collectibles, Hard Cases and secondary objectives indicate that campaign levels contain optional material.
That creates opportunities for replayability.
Players can complete the main story once and then return to previous missions to search for missing items.
Difficulty achievements also encourage multiple playthroughs.
A player might complete the campaign normally before attempting Insane difficulty.
Another player may immediately begin a co-op run with friends.
The structure therefore supports several different ways of experiencing the same story.
Unreal Engine 5 Powers the New Gears
Gears of War: E-Day has been built from the ground up in Unreal Engine 5.
Xbox says the game is designed around improved visual fidelity, modern movement and a darker, more frightening tone.
The engine upgrade allows The Coalition to create more detailed environments and larger battlefield encounters.
That becomes particularly important in Horde Siege.
Larger maps, multiple players, more enemies and larger set pieces require significantly more technical capability than the older games.
The Achievement list does not show technical details, but Xbox has already confirmed that the game targets 4K and up to 60 FPS on compatible displays across campaign and multiplayer. (xbox.com)
E-Day Returns to the Horror of the Locust
The new game is also being presented as darker and more frightening than recent Gears entries.
The Locust invasion is at its beginning.
Humanity is not prepared.
The enemy is unfamiliar.
The world has not yet adapted to the war.
That creates an opportunity for The Coalition to restore some of the horror associated with the earliest Gears games.
Xbox has described the Locust and other threats as more terrifying, while introducing new creatures and villains.
The Achievement names reinforce that tone.
Several revolve around disturbing biological enemies and brutal close-range executions.
Marcus and Dom Are Back
The campaign follows young Marcus Fenix and Dominic Santiago.
That is important because E-Day is not just another entry featuring the same heroes at a later stage of the war.
It is an origin story.
Players see Marcus and Dom before the events of the original Gears of War.
Their relationship is therefore central to the game's emotional direction.
Xbox has repeatedly emphasized the theme of brotherhood and hope despite the devastating situation.
The Achievement list adds another indication of the campaign's structure but keeps most narrative details secret.
That is likely deliberate.
The October 6 Release Date Is Getting Closer
Gears of War: E-Day launches on October 6, 2026.
Premium Edition owners receive up to five days of early access, beginning October 1.
The game launches on:
- Xbox Series X|S
- PC
- Steam
It will also be available through Game Pass at launch.
Xbox Play Anywhere support allows compatible purchases to work across Xbox console and PC with shared progression.
The wide availability means E-Day is being positioned as a major Xbox and PC release rather than a console-only sequel. (xbox.com)
What the Achievement List Means for Players
For casual players, the Achievement list provides a preview of the variety inside E-Day.
For competitive players, it highlights a serious long-term commitment.
For completionists, it may be intimidating.
The 25,000 Versus kills requirement alone could take a huge amount of time.
Then there are 50 Horde Siege missions, four maxed classes, collectibles, side missions and an Insane campaign completion.
The list suggests that players who want 100 percent completion will need to experience virtually every system the game offers.
The Biggest Achievement Is Also the Most Revealing
“Dead Serious” may be more revealing than the Achievement list's campaign milestones.
It effectively turns full completion into a test of mastery across the entire game.
You cannot simply be good at campaign combat.
You cannot simply grind Versus.
You cannot simply specialize in one Horde class.
The final challenge requires competence everywhere.
That strongly suggests The Coalition expects players to move between the game's different modes instead of staying in a single activity.
What Players Should Expect at Launch
Players should expect three major experiences.
The campaign provides a cinematic Emergence Day story with Marcus and Dom.
Horde Siege offers large-scale four-player PvE with class progression and resource management.
Versus provides competitive multiplayer with ranked and social options.
The Achievement list adds another layer by rewarding players for exploring, experimenting and mastering all three.
That gives E-Day a much broader scope than a traditional Gears campaign.
Gears of War: E-Day's full Achievement list gives players one of the clearest previews yet of the game's overall structure.
The campaign contains five acts, co-op support, collectibles, secondary objectives and hidden Hard Cases.
