UTGOTY was the first ever MP deathmatch game I played and I think its the best! At the time (2004/2005) I was really a retro gamer and didn't like FPS's that much. BUT DAMN, THIS GAME IS AWESOME! The graphics are pretty good, the gameplay is addictive as F***ing hell! and its even better with friends! (kind of obvious though!
Buy this game! If you haven't played it before and even if you have, GET IT! Its a measly $9.99 USD!
OR ELSE I'LL HEAD SHOT YOU!
