Today I announce that ARCH ULTRA is now open source. Everyone is now free to look at the complex eventing behind this game to see its inner working. I strongly advise to play the game normally first if not done already. The game data contains multiple elements from previous story revisions. You are bound to find some weird stuff. You will need a copy of RPG Maker VX ACE to open the game project file.
The source is a separate download (see download section), it is not the main download. It is also accompanied by a PDF file that document some development stuff.
