This game is great. It is an improvement over the PS2 version. The graphics have been improved very much, and many bugs have been fixed.
First off, the graphics are great. The character models, guns, vehicles, everything looks better. The frame rate is much better. The best part of all is that you can see much farther down the city, which also means you can shoot farther as well. But the is something that really bugs me though, the inger are all stuck together! It's like everyone had the idea to put super glue between their fingers.
The game controls well, and the new targeting system is much better than before, allowing you to shoot anywhere you want, which means you can use guns like the minigun to shoot down those pesky police choppers. While everything controls well, there are problems controling vehicles with a keyboard.
Well, there isn't much reason to get this game if you already have it for PS2, or XBOX, but if you don't, and you have a good computer, then you really should pick this one up.
