Granted the humor is gone but this game is a lot of fun if your playing with the right person.
Now there is a huge difference between a 'fun' game and a 'great' game. While great games should be fun this game is purely fun. The reason I found this game to be fun was the gun customizing of course but mostly if you are playing with a buddy who you enjoy playing games with it's a very fun game. On the other hand if you are playing with a random guy online who just waits for you to kill everything then it gets rather annoying.
Its a good looking game but there are some hiccups, if you spend 10 minutes making a new gun then die before a checkpoint guess who has to make that gun again. While that is my biggest turn-off this game was just overall fun, doesn't have a great story but if you are looking to shoot some stuff and turn an AK-47 into a frankenstein hybrid then you have come to the right place.
