"That Resident Evil Mod" is a total-conversion modification for the game named "Deus Ex". It is based on a game called "Resident Evil", which features a whole new single-player adventure, and a Co-Op Multiplayer. Better not forget your First-Aid-Spray, or you will not be leaving the mansion alive!
This is the basic set-up for the puzzle to replace use of Multitools on keypads.
It's the puzzle from the chemical room in the Guardhouse of Resi 1. (original, not remake)
It's all working too! :D
