I downloaded Moon from the main site, and am up to that door boss. How do I beat it? Are my shots with the Super Assualt Rifle and Moun Pistol even affecting the g'darn thing? I know it's a bit too early to ask for help regarding this game, but if anyone's up to where I am, could they please tell me how to kill it? Its a door that shoots yellow bullets at you.
You have to shoot it when it the door hole opens up to shoot at you. If you are damaging it it will blink a bit. Keep doing that til it dies.
On a more elaborate note you use your little rc probe to get close and shock it and quickly switch over to your best wep (probably your moon shot pistol) and unload... rinse and repeat until it explodes.
