Zerglings are popping up everywhere and it's up to you to stomp them out!
Controls:
Left click fires a sniper - kills zerglings in one shot, hydralisks in two and roaches in three.
Right click fires an artillery round - kills everything in one shot with reasonable a splash radius.
Nuclear Strike (Click the button, or press N) - Kills everything on the screen and halts new spawns for 5 seconds.
The zerg units will despawn after several seconds if not killed, penalizing you a life. You lose if you run out of lives.
