Ok i have played and beat almost all the FPS and when i say all i mean all to date and let me tell you not one of them are as phenomenal as this one this is the way a FPS shooter should be people everything from the gorgeous graphics to the epic gameplay its all near perfect its beautiful even if your not a FPS kinnda guy you should still try it out im not a huge si-fi guy myself but this game changed that i played the other two and i have to say this one is by far the best so if you like an amazing FPS and gorgeous graphics and an epic story get KILLZONE 3.
Me being myself I always loved playing AI for a small challenge. COD never gave me that, neither did anything else. Black ops' AI was TERRIBLE! Botzone has al the fun stuff Battlefield 3 has but even more. The AI is pretty difficult at Recruit so be careful. Also, try out the campaign; thats fun too. Playstation Move compliments the first person combat as well. TRY THIS GAME ITS GREAT
