Apocalypse Inside is born from the back-story of the Deus Ex saga. It revives everything in Deus Ex that didn't make it into the game including the story, levels, textures and easter eggs.
The cut mission from Deus Ex, resurrected in Apocalypse Inside. Reading the backstory of Deus Ex won't give you many spoilers, I have some surprises in mind for this level ;)
I'm so glad this mod isn't dead. I'm looking forward to meeting Adam Jensen and Ben Saxon and playing cut levels in the classic Deus Ex engine.
