if you are looking to get 100% enemies on a level search for all push walls every turret and sleeping mutant counts. In order to get all points you must collect all loot and 100% kills. black stone hides both in secret rooms that may require more than one push to open also some are stacked check the auto map for large empty spots walls with the crate pattern are very push wall prone. turrets can only be shot down with the automatic weapons. keep the plasma launcher holstered when scientists are in a room unless the map lists no informants on a level. when you are fighting the mutants conserve ammo only human guards, mech warriors, and mutated guards will drop ammo.each episode of AOG contains 11 levels 10 can be reched if you find the red key on level 9. 11 can only be reached by ateleporter hidden on one of the levels.

How does one holster the weapon in this game?

You can't.

What a crappy game

I didn't think so, but based on the ramble up above, I thought I'd double check.

I meant switch to another firearm. the plasma luncher is like doom's BFG 9000 it kills every thing in the direction you fire in.
