Just your everyday afternoon cop TV soap opera.
You shouldn't be playing this game for its story, but, in case you are, the game follows Jack Slate and his dog, Shadow, as they try to avenge Jack's father. Along the way he'll get framed, he'll escape jail, face betrayal, discover corruption and follow the entire gamut of action-cop movie tropes you think off the top of your head. The story is silly and cliched, the game knows it and it never takes itself seriously: you'll face thong-wearing ninja twin babes, a mad shooter that heals himself by drinking liquor and a cartoonishly abusive jailer. It's dumb, it's fun.
Luckily, Jack has a ton of maneuvers at his disposal to make short work of his enemies. Tapping circle while unarmed will perform an instakill that disarms his enemy, and tapping circle while holding a gun will let you grab an enemy and use him as a meat shield. The triangle button can be use to dive, and if you've stamina, you can dive in slow motion and pump your enemies with lead. You an also use circle while next to a wall to stick to it and take cover. Lastly, there's a fourth gauge, below your health, stamina and armor: Shadow. When full, you can use shadow to instantly kill an enemy and have Shadow bring you his weapon. Everything works really well, and it's a blast to play because landing bullets feels good, and once you get a hang of every mechanic, it turns very stylish as well.
My biggest annoyance with the game was that sometimes enemies will respawn indefinitely. It's not unusual to be picking up weapons after a firefight only for an enemy to respawn behind you, heck, some of those times they respawn from areas you just completely cleared out of enemies! While I never died to a random respawn or during the endless waves on certain missions(Mission 15 being a big culprit, since until you realize that you're supposed to go through a certain door, you might be tempted to try killing everything) they certainly were annoying.
