What is better the game Kane and lynch dead men or unreal tournament

Depends on your preference. Personally, I found Kane and Lynch to be quite buggy and disappointing. The cover system is broken, and the movement and weapons feel a bit quirky, I think that Unreal Tournament (I am discussing UT3) is much better. Although it lacks any "real" campaign component (Campaign simply consists of matches against computer controlled bots) the multiplayer is fast-paced, well-balanced, and fun. Remember, this is simply an opinion. UT3 was given an 8.5 (Gamespot) and a 9 (IGN) while Kane and Lynch received less favorable reviews, a 6 and a 7 from Gamespot and IGN, respectively.
