Damn outright good!
1st of all.... hands down to the creators. It's really a good game. But I have to adress a little glitch in the game. This is probably evident only with those with slow internet connections. There are times when the bosses fire and you can't move. You get stuck. Then you get killed. Other than that, It's one of the best games here. Keep em coming. What I have wanted for sometime with this is that they should've put AI characters. Since you have a base and all, why not other Non-Zombie Boxheads to help you? Kill Zombies!
