Gun mecanics are simply WONDERFUL. The bullet time is straight on point, and the level design is precise enough to create an action game in which you feel endangered. Guns are varied, so are the situations and objectives. One mission is an escort mission, another one is a sniper assist mission, another one features a lot of plateforming, another one is a giant ghost train featuring small puzzles, another one is a race to find back your weaponery...

Characters are iconic and quite well written. It is as goofy as parodistic as... I don't know, serious? Sam Lake does seem to be serious about it... Boss fights are great, mise-en-scène is inspired. The pace is 20/20, the game length is ideal. Art direction is strong even nowadays.

I see no reason for you not to play except the PC version is, apparently, bad. Like really bad.
