FEAR is a first person horror shooter that can freak you out at times. It features really intelligent AI who will work together to flank you and perform other realistic military tactics. To counter this your character has supernaturally fast reflexes, the games way of simulating this is giving you the ability to slow down time with a recharging bar. The bullet time slowdown effects look especially nice with some impressive bullet trail and explosion effects. The game features a very fast paced multiplayer experience which has since become available completely free from http://projectorigin.warnerbros.com/fearcombat/main Multiplayer has several game modes such as Deathmatch, Team Deathmatch & CTF (your standard fare) as well as adding Slow Mo Deathmatch which puts one slow motion powerup on the map and whoever has it gets the ability to slow down time for everyone. Multiplayer features a nice variety maps set in offices and factory warehouses. The game also contains a level edtior.
