Whether you think psychedelic guns are cool or happy smiley faces will make your weapons look tough, you can experiment with some crazy gun options in Army of Two: The 40th Day. A new trailer was released that showcases the game’s extensive gun customization feature and gun-fanatics will not be disappointed.

The original Army of Two already had a grand fantastic gun customization feature that seemed like it was already at its peak. Yet amazingly the sequel has tons more barrels, attachments, triggers, harnesses, and stocks. I imagine some gamers could stay jammed in the gun creation screen for hours just tweaking with their weapon.

In the following trailer you can see how an AK-47 gets a complete makeover into a light-machine gun while a sniper-rifle gets turned into an uber-sniper rifle.

The game is due out this upcoming January in 2010 for the Xbox 360 and PS3. You can learn more about Army of Two: The 40th Day by visiting the Official Website.
