There should be a STAMINA power-up. Say you have the Railgun, for example. You know how it takes a while for it to reload? Well, if you have the Stamina "drug" the yellow bar will be 2x as fast! For example, your turret takes about, lets say, 5 seconds to reload. If you have stamina, it will take 2.5 seconds to reload. I think it should be dropped rarely, and the crate color is BLUE. ​I believe the design on the crate should be a lightning bolt. I think it should cost 100 - 200 crystals. Me (TheMaffMan), and my buddy, im2slow4u, thought of this.
