This game released on Steam Early Access yesterday and although it may look like just an Overwatch rip off on the surface, it can actually be a lot of fun at times even if a bit buggy. It is free to play but the micro-transactions only unlock exclusive cosmetics or characters earlier. All characters and cards (the only two gameplay affecting factors) can be gained without spending anything.

Anyone else tried it out?
