Reviewing every game I've played in my Steam Library. Game 8.

Excellent coop platformer/shooter.

Wide variety of "Bros" and lots of levels and puzzle like destruction to get through.

Can be played local or online coop.

A very fun game.

Reccomended

dude this game is the definition of AWESOME, BROTASTIC, IT MAKES YOUR DAY BRO, AND IT MAKES YOUR NIGHT BRO, IT BROS ALL THE BRODAMN TIME, HOOOOOOYAAAAAAAAAAAWH

I first encountered this game on Miniclip in the form of a browser-based demo. I don't know if it used Flash specifically, but it was like a Flash game.

This version is enhanced from that one. I may have found the pixel violence and gore hilarious rather than cool.

PROS:
Killing enemies and destroying terrain is awesome
There's a lot of variety in the playable characters, from one that functions like the Ice Climbers in Smash Bros. to melee characters to guns to rocket launchers to flamethrowers to dynamite and more

CONS:
I often have to repeat sections due to carelessness leading to running out of lives (and all of your playable characters die in a single hit, though some enemies take multiple hits)

Overall, this game is worth getting.
