The Eternal Cylinder

The Eternal Cylinder
Developer: ACE Team Publisher: Good Shepherd Entertainment Platforms: Windows, PlayStation 4, Xbox One, PlayStation 5, Xbox Series X and S Released internationally: September 30, 2021 This game has unused areas. This game has unused abilities.

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article? Notes: There is multiple versions undocumented, many animations, models, textures and sounds undocumented. Plenty of vague language, too.

To do: Make separate pages for the march beta, day one release, steam demo, and endless mode build. The day one release and march beta have .pdb files, try using those to enable unused content/cheats. There's debugging and cheat blueprints; enable them if possible. Add the unused mutations, mentioned by strings, images, and the developers. Add old versions of strings from the beta, and add an unused string about temporary mutations. Fix the "Error tile, being just smoke" to instead show the actual contents of the map - the smoke tile is what is directly below the map which for whatever reason you spawn into. Bring over all the stuff from the wiki. Plenty of sound variations are suggested to exist are missing - which ones?

The Eternal Cylinder is a survival adventure game where players control creatures called Trebhum trying to survive while being pursued by a massive rolling cylinder.

Unused Areas

Several unused maps exist in the game files:

Name	Image 1	Image 2	Description
/Game/Maps/Tests/Trebhum_buildings.umap			As the name implies, it contains buildings used throughout the game, and models of fauna without any AI.
/Game/Maps/Tests/TestTrebhumCustomization.umap			An unimplemented customization menu. Allows you to choose from most mutations, skin colors and patterns. Pause menu can be opened via tabbing out, and the main menu with esc, suggesting this would have been an option.
/Game/Maps/Tests/Test_Peninsula1_AnchorRef.umap			Does not load, instead uses the Error tile, being just smoke.
/Game/Maps/Tests/test_ghaaarcrush.umap			Flat area filled with Great Ghaaar, used for testing the cylinder crushing them. 4 towers are present, but the cylinder phases through them. This map, minus the Ghaar, was used by developers to gauge how different Cylinder speeds feel.
/Game/Maps/Tests/Test_FriendTriggers4Plateau.umap			Does not load, instead uses the Error tile, being just smoke.
/Game/Maps/Tests/Test/test_pickables.umap			Map used to test items, collecting Trebhum, and mutations. If you don't switch Trebhum, you cannot pick anything up. This seems to be an issue when you use any map other than the default in most editions.
/Game/Maps/Tests/placeholder/placeholder_flat_terrain_far.umap			Does not load, instead uses the Error tile, being just smoke. Likely used for placeholder_flat_terrain
/Game/Maps/Tests/placeholder/placeholder_flat_terrain.umap			Flat land which looks to be a test for the LOD system, the terrain is bumpy in the distance, likely thanks to placeholder_flat_terrain_far. AI is broken here and doesn't move.
/Game/Maps/BiomeTesting/Custom/CustomBiomeDataTest.umap			Endless terrain without towers. Varies between game editions - in the current steam release, you spawn in a massive tundra, but in the steam demo you spawn in a savanna near a desert. Cylinder is always rolling.

Unused Mutations

The Trewhaala eyes mutation is a scrapped mutation intended to complete the Trewhaala mutations. It is only accessible via console commands. It was originally planned to be the second mutation of the Trewhaala series, as its fragment is known as Trewhaala fragment #2, which makes sense as the other three Trewhaala fragments have the numbers 1, 3, and 4.
