Definitely a must buy for all GTA fans....
Graphics: 7/10, I was actually very unimpressed with the visuals and overall texture of the city and the characters. It could have been much better(Rockstar did a much better job with Red Dead Redemption)
Audio: 9/10, fantastic voice acting, great gun sounds and car's engines sound very realistic.
Story: 10/10, probably one of the best in the series.
Gameplay: 8.5/10, while it's much harder to sprint/run and drive cars, the new cover system adds great combat capabilities and overall everything else works great.
Multiplayer: 9.5/10, one word, FANTASTIC! The multiplayer adds unlimited playability to an already unlimited playability game.
Overall, the game does have a few graphical issues and bugs such as when you are drunk you can't use your cell phone on foot but oddly enough you can use it while you are driving. Thats funny isn't it? Drinking, Driving and using your cell phone! Another thing, I never understood why they make GTA games so difficult(maybe thats just me) that you are forced to use cheat codes to beat the game?
