TNM is a huge singleplayer mod for Deus Ex based on the gaming community, finally released after 7 years of development.
It's really hard to review something which is SO good, but here goes: This is one the best mods I've ever played. Everything in the game just clicks in the right way. The story is funny and makes you addicted to it. The characters are unique and hilarious. The levels look breathtaking and the size of the levels is amazing. Very often I stopped playing just to look at the beautiful design. Gameplay is excellent (naturally, since this is DX mod after all), with nice little tweaks and lots of secrets to go around. Music is engaging and a pleasure to listen. All around, this is a perfect package for anyone who wishes to see more of DX. A perfect 10/10, I'll be coming back for this mod again and again, and so will you.
