check here for the complete guide, including all pickups, enemies and weapons: http://scratch.mit.edu/forums/viewtopic.php?pid=944315#p944315 A,S,W,D or arrow keys to move, click to shoot, space to switch weapons, to pick up weapons YOU CAN'T SWTITCH BACK!!! Only 5 weapons at the monent, the ants are your enemies, they have 5 HP (5 hits or 1 explosive hit), You currently cannot die, by the final version, there will be loads of weapons and more enemies. There is no objective, just wave upon wave of enemies, for the first 5 seconds of a wave, enemies can respawn infinitely. Have fun!
