"The Empire" Mission is pretty B.S. , I have 1,000 points to work with , there is no way that they are using 1,000 points as well , I get crushed within 15 seconds , mages cannnot even get a 21 sec spell off , but they have that sniper in the back killing everyone.
Give the Engineer (Ray) a better main weapon , the grenades are too unwieldy , slow , low damage , other then that this is an amazing entry into the bullet hell genre of games.
