The Serious Sam franchise is known for being insane, over-the-top, funny, and an overall satisfying experience. Though each game in the core series is a first-person shooter, developer Mommy's Best Games has taken the franchise in a different direction, turning it into a platformer and dual-joystick shooter hybrid with a heavy emphasis on chaos. A PC version was released in 2011, but this new XXL version comes with more content, including local cooperative play.
It's definitely over-the-top, as evidenced by the ability to literally stack guns on top of each other, and feels like a solid Serious Sam game. It is by no means a groundbreaking title, but it is good, old-fashioned nonsense that may or may not elicit a chuckle from time to time. Probably not, though.
