Broforce is currently doing the Steam Greenlight dance, but in the meantime, you should do what I did and watch the trailer below. The game started out as a Ludlum Dare entry that became a bit more serious, whilst being completely over-the-top:
Broforce is a hyperviolent action platform game. It features 90′s blockbuster movie action heroes making up the Broforce team- an under-funded vigilante paramilitary organisation – saving the world from satanic alien terrorist investment banker businessmen in non-stop, fast paced co-operative strategic mayhem filled with more action and explosions than anything else, ever.
There’s a web-based “brototype” of the game to try out, with the full version expected by the end of the year.
