Ashes is a Post-apocalypse themed total conversion for the GZDoom engine. It combines old school build style level design and Doom style action with a twist of Stalker and Fallout.
Features:
- 2 full episodes and an expansion offering dozens of intricate maps to explore, scavenge and fight through.
- A deadly arsenal of weapons from lowly 9mm pistols to improvised garage railguns.
- Fight varied enemies including: insane bandit raiders, mutant cannibal warlords and acid spewing carnivorous plants (protip: bring your flamethrower).
- An absolute banger of a soundtrack by cacoward winning musician John S.Weekley (aka PRIMEVAL).
Doesn't seem open source, i don't see i link to something like github or a license.
Search GzDOOM and FreeDoom, with which ashes is made+community made wads. Ashes normally is only a mod for the original DoomII engine, but this standalone version use the GzDoom engine and FreeDoom, both FOSS. Apart use diferent wads, not the original Doom Wads, which are proprietary. Its similar to The Dark Mod, which in it's first version was an mod for DOOMIII, but with v2 it becomes standalone with the own DarkRadiant engine (OpenSource) and community made Missions (in more than 120 missions so far created by different users of the community it is impossible for there to be a unified license, depending on the assets they had used).

That does not mean it fits the open source definition , that you can change it and even sell it
Unclear licensing can be a problem , see for example how cataclysm dda had to remove a tileset due to it.
Yes, but always is a problem with FOSS in case of complex apps or games, which need several different licenses. There isn't a more complex game which is full FOSS. For Example FreeDoom is Foss, but without the original Doom wads, at least the basic shareware wads, you can't even play it. In Ashes they had used a conversion with the GzDoom engine with wads made by users. But which license it has depends on every user which had create a wad file. In The Dark Mod the engine and the editor are OpenSource, but every map created may have a different license, maybe OpenSource or CC, depending on the license of the art assets used for it, OpenSource when they are the default assets of the editor, but if not, only the author knows, maybe own designs or from third party repos. Uniied licenses are only possible in simple apps and games, because of this there are very few OpenSource games out of table games or sidescrollers of the '90. Not so easy with FOSS in some cases.
You can't put TDM and Ashes in a repo of a commercial Linux distribution.
