The short version
- OpenCAGE, the Alien: Isolation mod toolkit, has reached version 1.0.
- It supports custom maps, missions, modes, characters, weapons and more.
- Matt Filer has worked on it for nine years, after two and a half years of prototypes.
Alien: Isolation's mod tools just hit 1.0. OpenCAGE, the toolkit Matt Filer has been building for years, has reached its full release, PC Gamer reports.
The feature list is big. According to PC Gamer's headline, the tools now support "full custom maps, missions, modes, characters, weapons, animations, sounds, models, textures, and more".
That's a lot of room to play with in a game built around one very hungry xenomorph. Custom maps and missions mean you could, in theory, see entirely new stretches of Sevastopol-style dread built by the community.
This has been a long road. Filer officially started work on OpenCAGE nine years ago, and that came after two and a half years spent on prototype versions.
The tools haven't been locked away during that time. They've been available for anyone to use throughout development, which PC Gamer points to as part of the reason Creative Assembly's horror game already has a variety of mods.
One exception is the VR mod. That works differently, since PC Gamer says it actually enables an unfinished mode that shipped with the game.
PC Gamer's coverage didn't spell out what specifically changed between the last pre-1.0 build and this release, so if you've been using OpenCAGE already, the release notes are the place to check.
What we don’t know yet
- It isn't clear exactly what changed between the previous OpenCAGE build and 1.0.
- Creative Assembly hasn't commented on the release.
- No new mods built with the 1.0 tools have been named yet.
