I liked this for Arcade mode only , has AI bots looting and you can either side with then or back stab them in the end to take all the loot . Aside for story , its the least part of the game and didn't enjoy it at all . Overall if its on sale i recommend for Arcade mode offline , really fun!
I strongly recommend if you love fast pace shooters, support up 32 bots if you love to play offline , awesome modes like team death match , capture the flag , vehicle ctf and many more , online too . Customization alright but best with mods , heh playin as master chief vs Mario ? that's too good lol , Get it if its on sale tho you wont regret.
