When using the Old Glory minigun, you can skip the time it takes to start up by switching from another full-auto weapon that you are currently spraying with Z. Merely switch weapons while firing to get insta-minigun fire
I have figured out Eagle Eye. Hit Z instead of holding it down, items will not show up on the map, it will merely show your position. Pressing it will enable a radar on the HUD.
Step 1: Get m79, get machine gun.
Step 2: Have assistant reload the m79 while you mop up with the MG.
Step 3: ???
Step 4: Profit. (dead zombies eerwhurr.)
Was actually pretty slick! Weapons and animations were pretty flawless, as well as the ambiance. I especially liked how the jump sound made it kinda feel like Quake lol
+ this if you think enemies crashing into your ship is one of the more effective ways of destroying them! cause seriously whats the point of trying to aim and shoot them if they're that fast and your shield is uber?
