remember monday night combat? for those that don't, it was a humorous and fun third person shooter/DOTA hybrid. actually, it didn't really fir into any category apart from insane amounts of fun. Super MNC updates it with new pros, new arenas, new bot, and new rules. the concentration is less on killing the enemy players outright and more on forcing them to fall back so you can escort your bots to their moneyball.
it is great fun, but the rules have changed. oh, and did I mention that it is supposed to be free to play?
so get it. then the only question you need ask yourself is how will you get their moenyball.

co-op zombie massacre. plenty of fn and interesting weapons with lots of interesting ways to destroy wave afte wave of the infected. chainsaw? check. rifle? check. two pistols? check. flamethrower? check. anti tank rocket launcher? check.
the real question about this game is if you don't have it, why have you not spent the minimal amount it costs, given that you will find that is it worth the money quite quickly.

None of the addictiveness of the hats and weapons drops from Team Fortess 2 means this somewhat similar third person shooter/strategy/DOTA/RPG hybrid can pave way for its unusual blend of humor and entertaining gameplay. you choose a class, and you must escort bots to the enemy base to destroy their moneyball. kill bots and enemy turrets and players along the way to upgrade your character with new abilities as well as spawn new bot waves, open up jump routes, fire ejectors, use the annihilator, or build and upgrade turrets at your base.
It is pure and simple fun, and quite worthwhile. Buy it if you have the very few dollars it costs, you will not regret it.
