No more online play. the main letdown for this game. A lot of new features but the new fighting style is boring...
Fighting styles. I'm not sure if it's just me, but timesplitters 3's fighting styles just doesn't feel right. I'm not sure why but it's so easy to take down the al bots, I mean even easier then it was before. On the good side timesplitters 3 actually has a real aiming feature, and that was nice. There's also grenades which adds on something else besides guns.
Vehicles: When I heard there was vehicles for this game I was like, wow, will be bots be able to man vehicles? On the mapmaker I noticed you could add a buggy which could have 2 people on it. When I tried it out, it turned out you couldn't even have a gunner, as if the buggy was just for transportation or running people over. The campaign has real vehicles at least, but the whole control scheme is horrible.
Conclusion: I think I'm one of the few who is actually criticizing this game compared to the first two. It's just my opinion though, I think overall if all you got is a wii or ps2 you should get this game. You can find it pretty cheap for about $15...
