“There Is Only War” contains three levels and a separate Purity Seal in each one. The complete route is 17 Secrets and 3 Purity Seals: four Secrets in The Trenches, eight in Munitions Mayhem, and five in Chaos In The City. If you miss one, finish the level and return through Level Select; the campaign’s collectibles can be revisited that way. The alternate branch becomes available after making another campaign choice.
Follow the level order below and treat wall presses, destructible objects, traversal jumps and container searches as deliberate collectible triggers rather than optional exploration.

Mission layout at a glance
The three levels do not hide collectibles in the same way. The Trenches is the shortest search by count and relies mainly on route checks and one key-area search. Munitions Mayhem has the largest haul and mixes shooting, wall searches and traversal. Chaos In The City concentrates its collectibles around vertical buildings, a bridge and exterior ledges.
| Level | Secrets | Purity Seal | Main trigger types | Backtracking risk | Landmarks to watch |
|---|---|---|---|---|---|
| The Trenches | 4 | 1 | Route-end checks, a lower trench, a right-side detour and a container search | Low if you inspect side routes before advancing | Metal trenches, sniper trench, purple-hued building, purple-key console |
| Munitions Mayhem | 8 | 1 | Skull shooting, wall presses, a missile jump, train-station exploration, a jump pad and a hidden room | Highest; several checks sit around major combat arenas | First hall, first Purge’s upper corridors, silo, underground station, globe projection |
| Chaos In The City | 5 | 1 | Building holes, bridge traversal, debris climbing, statue searches and an exterior wall route | Moderate; vertical routes are easy to pass without looking back | Red-key building, bridge, destroyed buildings, purple door, multi-floor building |
Secrets and Purity Seals are tracked separately. A level can therefore be complete for one collectible category while still missing the other.

How to use this guide and recover a missed collectible
Finish the level before replaying it
The available route for revisiting campaign collectibles is Level Select after you have finished the relevant level. You do not need to restart the entire campaign simply because one item was overlooked during the first run.
Replay the correct branch
“There Is Only War” is a branch rather than a single uninterrupted level. The alternate branch becomes available after another campaign choice. If a level is not listed in Level Select, complete the preceding campaign choice that unlocks that branch, then check the selector again.
Use landmarks, not memory of combat rooms
Most of the instructions below are tied to a specific object or route landmark. When replaying, stop at that landmark and perform the interaction even if the arena has already been cleared. A skull behind boxes, a green switch beside a globe projection, a train and a statue are more reliable reference points than the names of combat encounters.

The Trenches has four Secrets. Its route is compact, but two collectibles are separated from the obvious forward path: one is below a sniper-filled trench and another is on the right after the purple-hued building.
Secret 1: end of the metal trenches
- Play through the first Purge.
- Pass through the metal building and enter the metal trenches.
- Continue to the end of the trenches. Search the terminal end of this passage before moving on; this is where the first Secret is placed.
The important landmark is the transition from the building into the metal trench network. Do not stop at the first open section; the collectible is at the far end.
Secret 2: lower section of the sniper trench
- Reach the large open trench area populated by snipers.
- Drop into the lower section of that trench rather than staying on the upper route.
- Check the lower area for the Secret before climbing or leaving the trench.
This is a vertical route check. Seeing the sniper area from above is not enough; the collectible requires entering the lower section.

Secret 3: right side after the purple-hued building
- Leave the purple-hued metal building and enter the open area beyond it.
- Turn around the right-hand side of the open area.
- Follow that right-side route to the Secret before committing to the main path.
The building’s purple hue is the navigation cue. Once outside, the detour is to the right, not straight ahead.

Purity Seal: rear corridor platform after the red door
- Go through the red door.
- Enter the next room and find its rear corridor.
- Use the boxes in that corridor to climb onto the small platform.
- Collect the Purity Seal on the platform.
The boxes are the intended way up. If you pass through the room without checking its back corridor, the platform is easy to miss.
Secret 4: container beside the purple-key console
- Continue to the area containing the console that requires the purple key.
- Stand facing the console and inspect the container on its left.
- Collect the Secret from that container.
The console is the anchor for this search: the container is specifically on its left, not somewhere in the wider room.
Munitions Mayhem: eight Secrets and one Purity Seal
Munitions Mayhem has the most collectibles in the branch and the widest variety of triggers. The safest approach is to clear each major landmark methodically: the first hall, both upper corridors around the first Purge, the silo, the underground station and the final Purge area.
Secret 1: shoot the skull in the first hall
- Enter the first hall.
- Look behind the boxes for a skull.
- Shoot the skull.
- Use the left gate that opens and collect the Secret beyond it.
The gate is opened by the skull shot. If the left gate remains closed, return to the boxes and check that the skull was actually hit.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsSecret 2: wall at one end of the first Purge’s upper corridors
- Reach the first Purge and move into the upper area surrounding it.
- Follow one of the corridors to its end.
- Press against the wall at the corridor’s end to reveal the hidden route.
- Collect the Secret inside.
This is a wall-search trigger rather than a visible pickup. Approach the end directly and make contact with the wall instead of merely looking along the corridor.

Secret 3: opposite upper-corridor wall
- Remain in the upper corridors around the first Purge.
- Travel to the opposite end from the previous wall search.
- Press against that wall to reveal the second hidden route.
- Collect the Secret.
The two upper-corridor Secrets are separate. Finding one does not open or collect the other, so cross the Purge’s upper area and check the opposite end as well.
Secret 4: jump onto the missile at the silo
- Reach the silo section where the route requires you to jump down.
- Before making the normal jump down, land on the back of the missile.
- Use the missile as the traversal route to reach the Secret.
The order matters: jump onto the missile first. If you drop immediately, you bypass the intended platform and will need to revisit the level through Level Select.
Purity Seal: airship in the underground train station
- Enter the underground train station.
- Look to the right for the parked airship.
- Enter the airship and collect the Purity Seal.
The airship is a distinct vehicle landmark. It is separate from the train-related Secrets in this station, so inspect it before following the tracks farther into the area.
Secret 5: back of the far train
- In the same underground station, locate the far train.
- Go all the way to the back of that train.
- Collect the Secret there.
Do not stop at the train’s entrance or side. The collectible is at the rear end.
Secret 6: metal structure near the train
- Stay near the train containing the previous Secret.
- Climb the rocks beside it.
- Use the rocks to reach the nearby metal structure.
- Collect the Secret on that structure.
This is a traversal search layered onto the train landmark. After checking the train’s back, look upward and use the rocks rather than returning immediately to the main route.
Secret 7: green switch and jump pad in the final Purge area
- Reach the final Purge area.
- Find the green switch beside the globe projection.
- Press the switch to activate the jump pad.
- Use the activated jump pad to reach the Secret.
The jump pad is not usable until the green switch is pressed. The globe projection is the visual cue that distinguishes this switch from other controls in the area.

Secret 8: wall in the final area’s side room
- Remain in the final Purge area after collecting the jump-pad Secret.
- Enter the small side room.
- Press against the wall to reveal the hidden room.
- Collect the final Munitions Mayhem Secret.
This is another wall trigger, but it is not one of the first Purge’s upper-corridor searches. Treat the side room as a separate check.

Chaos In The City places its Secrets along height changes and exterior edges. The red-key building, bridge, destroyed buildings and the large multi-floor building are the essential route markers.
Secret 1: second-floor hole after the red key
- Use the red key and climb the building.
- Reach the second floor.
- Exit through the hole in the wall.
- Follow the route outside and collect the Secret.
The hole is the exit from the second-floor interior. If you remain on the normal stair or hallway route, you will pass the collectible path.
Secret 2: destroyed column at the end of the bridge
- Cross the bridge.
- At its end, use the destroyed column to reach the opposite side.
- Follow that alternate route to the Secret.
The column is the bridge’s traversal solution. Look for the broken section at the far end rather than searching the middle of the bridge.
Purity Seal: upper room in the destroyed buildings
- Proceed through the Purge and the sequence of switches that follows it.
- In the destroyed-building area, climb the debris on the left.
- Reach the upper room.
- Collect the Purity Seal inside.
The left-side debris is the access route. This Seal is above the destroyed structures, so a ground-level sweep will not find it.
Secret 3: behind the statue before the enemy-held walkway
- Before passing under the enemy-held walkway over the road, stop at the approach.
- Turn left.
- Check behind the statue and collect the Secret.
The timing cue is important: search before going under the walkway. Once you have passed beneath it, the statue is behind you.

Secret 4: upper ledge above the purple door
- Reach the room where two corridors meet above the purple door.
- Find the metal structure in that room.
- Use the structure to climb to the upper ledge.
- Collect the Secret on the ledge.
The purple door identifies the room, while the metal structure provides the vertical route. The Secret is not at corridor level.
Secret 5: exterior route from the third floor
- Near the end of the level, enter the large multi-floor building.
- Climb to the third floor.
- At the left statue, go through the hole in the wall.
- Circle around the building’s outside on the left.
- Collect the final Secret.
This is the longest exterior detour in the level. The left statue and wall hole are the handoff from the interior to the outside route; continue around the left side rather than dropping back into the building.
What to do when the total is incomplete
Use the level’s collectible count as a diagnostic
Because Secrets and Purity Seals are separate categories, first identify which category is short. If a level has all of its Secrets but not its Seal, revisit only the Seal route. If the Secret count is short, use the level landmarks in the relevant section above and check each trigger type in order.
Recommended Free Tools
Replay the level through Level Select
Finish the level if necessary, open Level Select, choose the specific level in the “There Is Only War” branch and retrace the missing landmark. The campaign’s collectible-revisit system is designed for this kind of cleanup.
Check both branches if a level is unavailable
If the selector does not show the level you need, the alternate branch may not yet be unlocked. Make the other campaign choice required to open it, then return to Level Select and select the branch containing the missing level.
Common mistakes and quick fixes
- Counting only Secrets: Purity Seals have their own tracking category. Revisit the Seal route in each level even after all Secrets are collected.
- Leaving after seeing a landmark: A skull, statue, train or globe projection is only a cue. Perform the specified shot, wall press, climb or detour.
- Taking the normal jump at the silo: In Munitions Mayhem, land on the back of the missile before jumping down.
- Searching the wrong side of a room: The Trenches’ final Secret is in the container left of the purple-key console; Chaos In The City’s statue search is on the left before the walkway.
- Assuming one wall trigger covers another: Munitions Mayhem has two separate wall searches around the first Purge and another wall search in the final area’s side room.
- Dropping from a vertical route too early: In Chaos In The City, use the second-floor hole, bridge column, debris climb, upper ledge and third-floor exterior route exactly where described.
Complete route order
For a single clean run, use this order: The Trenches’ three early route checks, its red-door Seal, then the purple-key-console container; Munitions Mayhem’s first-hall skull, both first-Purge corridor walls, missile, station Seal, far-train Secret, nearby metal structure, final-area jump pad and side-room wall; finally Chaos In The City’s red-key building hole, bridge column, destroyed-building Seal, statue, purple-door ledge and third-floor exterior route. This sequence follows the level progression and keeps each collectible tied to the landmark where it appears.
When every listed Secret and each level’s Purity Seal has been collected, the “There Is Only War” branch is fully covered.
