Shrink (Powerup) is a power-up which looks like a glowing green sphere that contains what appears to be a quartered grey orb. It temporarily yet dramatically shrinks the player, reducing their height to less than that of a monkey. With this power-up, enemies find it incredibly hard to hit the player because the user makes for such a small target. The effect of the Shrink power-up lasts for 30 seconds.
- When 'shrunken', the sounds of your guns firing are dramatically raised in pitch, yet the reloading noises remain the same.
