TNM is a huge singleplayer mod for Deus Ex based on the gaming community, finally released after 7 years of development.
I don't think I've ever played a game that so wildly surpassed my expectations. It is really hard to say because I love the original game so much, but The Nameless Mod is just the "better game". Better missions, better weapons, better characters, better ending, better everything! Which is saying a lot because we all know how great Deus Ex is.
This is easily a must play for any hardcore Deus Ex fan, takes everything that made that game great and expanded on it, as well as added its own spin on everything with HILARIOUS writing and a storyline that literally will have you on the edge of your seat. The ending is unique to the choices you made throughout, which is something that even a lot of games that are out today promise but don't deliver.
Great game, OTP. I just finished my second playthrough and I'm sure I'll be doing another sometime in the near future!
