thriller , short , good multiplayer

User Rating: 8.7 | Quake 4 PC
great game takes approximatly 20 hours or less to ccomplete , great variety of gameplay , scenery , mission types etc ( you can play as a walker, tank sometimes) . scares the hell out off you atsome points , theres also a lot of diffrerent enemies
sometimes there are some puzzles for example how to defeat a certain boss or somethings like that . you don't always play alone in singleplayer campaign some times youre with a team , (*note that ai team members can't die) . 10 different weapons should give you different ways to defeat an opponent. great multiplayer too . not too muck replay quality on singleplayer campaign
