A cool mod in the deus ex fashion. I still have to complain about the combat being the same as the deus ex one considering the improvements in that area in the mod project 2027 and the smoke mod, but despite that the mod is amazing. There is a whole lot to explore there is also a lot of tactics available for missions and the ability to kill no one if desired.
The story is quite well written and there is even the amazing option to avoid killing certain bosses. The open gameplay is still there and there is some goodies for brutes as well.
A good mod set in the deus ex universe.
