Gears of War: E-Day Achievements Explained: Campaign, Horde Siege and 100% Requirements

What the 55 Gears of War: E-Day achievements reveal about the campaign, collectibles, Horde Siege progression and the Dead Serious completion grind.


Gears of War: E-Day launches with 55 achievements covering the Campaign, Horde Siege, Versus and long-term progression.

The list is useful before release because it confirms several systems that will matter for a full GamersBeacon completion route.

Campaign Structure

The achievement list references five Campaign Acts.

It also confirms completion goals for:

  • finishing every Act
  • completing the Campaign in co-op
  • finishing on Insane difficulty
  • reaching 100% Campaign completion
  • finding all Collectibles
  • discovering all Hard Cases
  • unlocking all Supply Cache items

Individual mission and chapter names should still be verified from the final game before separate walkthrough pages are published.

Horde Siege Achievements

Horde Siege achievements cover both short-term objectives and very large grinds.

Publicly revealed requirements include goals involving:

  • completing Horde Siege missions
  • spending Energy at Supply Caches
  • completing Invasion Events
  • reviving players
  • unlocking and using progression systems
  • killing very large numbers of Locust
  • maxing Horde Siege classes

This makes Horde Siege one of the biggest sections for long-term achievement completion.

Versus and Player Progression

The achievement list also ties into competitive multiplayer and account progression.

Long-term completion involves Player Level, Re-Ups and a very high Versus kill target. Anyone going for every achievement should treat this as a multi-mode grind rather than a Campaign-only completion.

What Is Dead Serious?

Dead Serious is E-Day's modern version of the series' notorious Seriously-style challenge.

The overall requirement combines major completion goals instead of asking for one simple task. It reaches across Campaign completion, Versus kills, player progression and Horde Siege class mastery.

For a full 100% route, Dead Serious should be planned from the beginning rather than left until every other mode is finished.

What GamersBeacon Will Track at Launch

The achievement list gives us a clear completion checklist for launch coverage:

  1. Every Campaign Act and mission.
  2. Every Collectible.
  3. Every Hard Case.
  4. Every Supply Cache unlock.
  5. Secondary objectives required for 100% completion.
  6. Insane difficulty route.
  7. Horde Siege class mastery.
  8. Player Level and Re-Up progression.
  9. Versus grind requirements.
  10. All remaining miscellaneous achievements.

Specific solutions will be added only after their locations and requirements can be verified from the released game.
