An extremely enterprising Alien: Isolation mod project, OpenCAGE, has released its latest set of tools for the game: And demonstrated just what a big deal this is by unimportant Counter-Strike's Dust 2 map into Alien: Isolation and releasing the relentless Xenomorph and some Working Joes to hunt the player down (thanks, RPS). Obviously one would hope to never meet an Alien anywhere, but a big open space where your only protection is wooden crates certainly doesn't seem ideal (though weirdly enough is basically a reduction of the unmade Alien 3).
"I've just released a big update to the tools that adds support for custom meshes, materials, and textures—something that has been requested for years," said Matt Filer, creator of OpenCAGE. "[It] also supports custom scripting in the game's proprietary scripting format, and modification of behaviour trees & a load of other game configurations."
