+foam gun tech cavitation - a knock back effect, and 1 out of 5 foam bullets are larger and faster?
+
+Tech: Turbine - Energy generation is proportional to your speed up to +X% energy generation at 40 speed 
+Tech: "Electric Reactive Armor": Defeanse increases by 2% for each 1 energy generation you have
+
 wormhole tech - teleport away mobs with mass below 3 when they get too near the player
     short CD, small energy cost, only mobs below a mass
 
-foam gun could have a knock back effect
-  maybe with pressure vessel?
-
 extend brainstorming animation timers to fps cap?
   will it be smoother or choppier?
   anything else needs to hit limited fps on a high fps monitor?
