When activated, it allows the player to transform into a large swarm of spider-like creatures for a limited time, that can overwhelm any enemy or teammate they touch. Any teammate or enemy that is affected by the swarm will have the spiders crawl over their skin, eventually killing the player. If someone shoots an explosive weapon or throws a grenade near the spiders, it will kill them and warp you back to an area which was close to where you activated the kickback and this ends the kickback. In the Summer Beta, if you kill someone who is using Creepy Crawler, then you will get the medal "Down Came the Rain" which awards you $500.
