http://www.mediafire.com/file/mdn2j4fzmf1/DiA.exe
couple new enemy's---
Baddies: the first little red dudes you face, basically cannon fodder.
Critters : little robot/bunny things, die in 1 hit with everything, but hurt you pretty good if they touch you
Grunts: green dudes, there health and number of shots fired goes up exponentially with every wave
Lava Ticks: walking bombs of lava, they also get more health when they walk threw lava
Beetles: flying annoyances
Juggernauts: have a force shield that gets stronger when more Baddies are around and shoot plasma.
Ill add the targeting sites and 1player 8 direction movement in my next release...
