The goal of the game is to eliminate all enemy bots. Use arrow keys to move and WASD to fire at 4 directions (hold down the button for rapid fire). Player has 300 HP until death... and that's not much...
You can move only vertical or horizontal direction at the same time, and movement automatically stops at crossroads (you can invert the movement direction).
Enemies come in groups of 3+ starting from lazy easy form, after destroyed they transform in more healthy and powerful medium form and finally into tough, quick and rapid-firing hard form.  Occasionaly hard form after being destroyed transforms into boss form (the name says it all).

P.S. Does anybody need those droids I've made based on Skorpio's construction set to upload to opengameart?

P.S. I'd be very thankful if anybody could test the game against story and other maps being too hard. Especially multiplayer, as far as I have no-one to play with
