Power-Ups are pick-ups sometimes spawned during a match. They all have a certain effect to help the player, usually for a limited time. They also always are shown as something that represents the power-up, floating with a green aura around it.
Canon Power-Ups[]
The QED also sometimes leaves some exclusive power-ups. An example is the Gun Drop.
Non-Canon Power-Ups[]
There are also numerous Non-Canon Power-Ups as well.
