Summary: If you don't mind "cartoon characters" (e.g. League of Legends) and Team Fortress 2 does not cover your role playing, Brawl Busters is the game for you. Short, fast, exploding games lots of fun, good community. Has PvE game modes also, even though PvP is more dominant. Hosting servers have space for improvement, but so far they fulfill their job pretty well.
Summary: A couple friends and I picked this up after we saw it for free on Steam. After the annoying launcher and account setup (you'll also have to disable MSI Afterburner or other overlay programs) we finally got the game running. It's full of arcadey action, instant gratification, and easy to pick up play style. It has a great survival mode with waves of zombies, but I'd like to see more coop modes in the future. I'd recommend this game to anyone.
Summary: Brawl Busters is an entertaining Player vs Player game that, to me, is very reminiscent of games like Team Fortress 2. It's cartoony, in a good way, mirrors TF2's clear silhouettes (it's obvious, just by looking, what you're facing off against), and has fast, fun, and generally well balanced combat. The six classes available are very distinct, and each plays a clear role. It has a few modes (TDM, Capture the points, co-op vs Zombies) that are all well done.
