Glitchy, crashes sometimes on IE when I start trying to search a building, sometimes invisible zombies and invisible survivors, laggy on google chrome. 1/5 for poor game performance
mission 10, the way I started was turtled with all 3 of my bases in the top left corner, use mortars to clear the first pool. don't worry if you stretch collectors to the 2nd pool, they're good to get a start off. you'll need 3-4 beam turrets to take out spoors, and start building some turret walls/bases at choke points and such
I keep getting little spots where the game freezes, than unfreezes, than suddenly I've taken an arrow to the knee :u but seriously, the dash and strike mechanic is pretty bad, very unreliable
