There's no worse feeling than raising your zombie to 100% Mood and 100% Humanity just to beat it up with boxing gloves and chainsaw it to death... It's like putting down a pet :(
At first I didn't know where to paste the _y = Math.random()*200 + 50; bit so I put it in the Ship.as... big mistake every time an enemy ship spawned it would teleport my ship to random parts of the screen.
Thankfully I found it now :P
