Way better than GTA IV!
Now this game I believe offers way more than gta does. First off you get to create your own character and the customization is really amazing from allot of clothing and tattoos. Excellent vehicle customization as well, adding rims, spoilers and body mods. It has a pretty sweet mini game zombie uprising which you just kill hordes of zombies, if that isn't fun I don't know what is. Then there's activities, my personal favorites are insurance fraud, mayhem, demo derby, fight club, septic avenger, and hitman. But you also have heli assault, snatch, crowd control, and races. Then of course from the first game there's the hidden cds, tags and stunt jumps. But newly added vehicles that the previous didn't offer include boats, helicopters, planes and motorcycles. Of course there is an online and from my experience with it, it is way better than there first but its still not great. It has its lag issues as the first one and for some reason everybody quits and wont finish a match. But the worst problem in the game is people are a bunch of rocket whores and a bunch of people will drive around in cars the whole match just trying to run you over. Last I'm disappointed in the soundtrack but there's still some descent stuff on there such as Trivium, Opeth, 3 Inches of Blood, and Lamb of God. And hit songs like Misery Business, Take on Me, Karma Chameleon, and Final Countdown. But this coming from me I don't like rap, rock , pop, or any real mainstream music.
Summary: Fun campaign and side missions with great character and vehicle customization. Cool mini game zombie uprising to give multiple plays. Hidden things scattered through Stillwater to find. Good but not great multiplayer and descent game soundtrack. Loads of play time to keep you busy.
