I played the free to play Brototype of Broforce, and I have to say it was fun. It's a side scroll shooter, where you play as different characters inspired by different action stars like Rambo, Ash, Robocop, and even the Terminator. The game is pretty strait forward shoot the bad guys, and save any other action heroes who are trapped in random cells. As you save these different action heroes you become that hero, which also gives you an extra life for each one you save.
As I stated above I played the prototype also known as the Brototype version of the game. You can pre-order the full version for release which looks like it includes even more action hero inspired characters, more levels, and the ability to play multiplayer with your friends.
In all it looks like it going to be a pretty fun game. If you'd like to try the Brototype click the link below..
