Gears of War: E-Day Collectibles Guide – Hard Cases, Supply Caches & Side Objectives

Getting 100% Campaign completion in Gears of War: E-Day involves more than collecting the standard lore items scattered throughout Kalona.

Across the five Campaign Acts there are 140 Collectibles, 125 Hard Cases, 36 Supply Caches and 17 Secondary Objectives. Each category is tracked separately and has its own related achievement, so clearing only the standard collectibles is not enough for full Campaign completion.

Type	Total	Related Achievement	What It Covers
Collectibles	140	Memories From E-Day	COG Tags, documents, photographs and other lore items
Hard Cases	125	Relax. I'm the Map.	Cases tied to Campaign upgrade progression
Supply Caches	36	Quartermaster	Campaign caches and their unlockable item pool
Secondary Objectives	17	Side Piece	Optional missions found while exploring Kalona

The safest way to approach 100% completion is to clear each area carefully before advancing the story, especially once the Campaign opens into larger districts where several categories can appear close together.

How E-Day Campaign Completion Works

The four completion categories are tracked separately, so finding a standard collectible does not also count as a Hard Case, Supply Cache or Secondary Objective.

The War Journal is the most useful place to check your progress. Use it before leaving a chapter so you can spot a missing item while the route is still fresh.

If you miss a standard collectible, you can return through chapter replay rather than restarting the entire Campaign. Larger open sections are still worth clearing on the first visit because some optional routes can take much longer to repeat than a simple linear pickup.

A good rule throughout the Campaign is:

1. Search nearby rooms, side streets and alleys before following the main objective.
2. Finish Secondary Objectives while you are already in the area.
3. Check the War Journal before crossing major story transitions.
4. Use the Act-specific guides below if your chapter total is short.

Collectibles

Standard collectibles are the main lore pickups found throughout the Campaign. These include items such as COG Tags, letters, photographs, posters, magazines and other objects connected to the people and events surrounding E-Day.

There are 140 standard collectibles in total, and collecting all of them unlocks Memories From E-Day.

When you get close to one, listen for the collectible audio cue and watch for the brief on-screen indication. In larger exploration areas, slowing down and checking interiors before following the objective marker can save a lot of cleanup later.

Collectible Guides by Act

Act	Guide
Act 1	All Act 1 Collectibles
Act 2	All Act 2 Collectibles
Act 3	All Act 3 Collectibles
Act 4	All Act 4 Collectibles
Act 5	All Act 5 Collectibles

These individual walkthroughs break the standard collectibles down by chapter and put them in a practical order so you can compare your progress against the War Journal without mixing in the other completion categories.

Hard Cases

Hard Cases are separate from the standard lore collectibles and are tied directly to Campaign upgrade progression. There are 125 Hard Cases across the Campaign, and finding all of them is required for Relax. I'm the Map.

The game alerts you when one is nearby, and Tac-Com can help reveal nearby cases. In larger exploration areas, some Hard Cases also appear on the district map.

Unlike standard collectibles, some Hard Cases sit in upper floors, side buildings or areas that only become accessible after progressing a nearby objective. If a marker appears unreachable, continue the current story objective and check the area again before leaving the chapter.

Hard Case Guides by Act

Act	Hard Cases	Guide
Act 1	0	No Hard Cases
Act 2	36	All Act 2 Hard Cases
Act 3	38	All Act 3 Hard Cases
Act 4	46	All Act 4 Hard Cases
Act 5	5	All Act 5 Hard Cases
Total	125

Supply Caches

There are 36 Campaign Supply Caches, and fully unlocking their available item pool is required for Quartermaster.

Supply Caches are separate from Hard Cases and standard collectibles. They are generally found along Campaign routes and in the larger exploration areas.

Do not confuse Campaign Supply Caches with Horde Siege Supply Caches. They use similar terminology, but their progression systems are separate.

Secondary Objectives

There are 17 Secondary Objectives across the Campaign, and completing all of them on any difficulty unlocks Side Piece.

They are found in Acts 2–4:

Act	Secondary Objectives
Act 1	0
Act 2	7
Act 3	3
Act 4	7
Act 5	0
Total	17

Some Secondary Objectives only become available after nearby story progression, so an inactive location may need to be revisited before leaving the chapter.

Best Way to Reach 100% Completion

If you are aiming for full Campaign completion, avoid treating every category as a separate cleanup run.

When the Campaign opens into a larger district, clear nearby buildings and side streets, complete Secondary Objectives, collect nearby Hard Cases and Supply Caches, and then continue the main objective.

Use the Act-specific guides above whenever you need exact locations. The standard collectible guides cover all 140 lore items, while the Hard Case guides provide separate routes for Campaign upgrades.
