-press Z+X in testing mode to trigger player death
+drones stop auto grabbing power ups when you have crystallized armor
+mod - non-Newtonian armor: take 50% less harm for 10 seconds after getting hit

-wave beam: mod - longitudinal waves (bullets oscillate fast /slow not up/down)
-  trigger on crouch?
-
 medium caliber gun in between minigun and rail gun
   mod: electricity damages mobs that get near the bullet 
   get ammo back if it hits mobs
