Crawlers are insect-like creatures that serve as vectors that transmit the Chimeran Virus. The strain is capable of limited flight, but they are often deployed by spire missiles, though they are kept in conversion centers and sent into holding pens where uninfected prisoners are kept. Upon locating their target, the Crawlers begin to penetrate the victim's body, usually through the airway passages of the mouth or the nose. Once this has been accomplished, they begin to inject the Chimeran virus throughout the body; after this process is completed, the Crawlers decompose into the host's body and complete the infection stage. After the Crawlers has merged into the host, who then abruptly falls into a coma, the virus begins the process of an inexorable conversion of the host into a Chimeran creature.
The Crawlers commonly attack in huge swarms to overrun the enemy. Added with their small size, this is a perfect infection strategy. If a Crawler fails to infect a host, it begins gorging on nearby dead bodies--human or Chimeran. After this, the Crawlers go through a metamorphic stage and encase themselves in cocoons. After an unknown period of time, the Crawlers mutate into Leapers and hatch from their pods. It is believed that the Crawlers originated from the Tunguska event.
Crawlers were also used to convert humans into Grims at one point, but later replaced by Spinners for this role.
By the time of the Chimera's invasion of the United States, Crawlers were beginning to become phased out and replaced by the Spinners. Apparently, the Crawlers are likewise evolving into deadlier strains such as The Swarm.
Crawlers made a minor appearance at the end of the level "Staten Island", in which a volley of Spire Missiles bombarded Staten Island and releasing their payloads. Tom Riley and Ellie Martinez were forced to flee from the swarm.
Resistance: Fall of ManEdit
- Crawlers creates a sound similar to the Australian Cicada and also look similar as well.
- They are one of the few non-combative Chimeran strains. The others are the Carrier and the Cocoon.
- The Swarm in Bryce Canyon is an advanced evolved form/strain of the Crawler.
- Although its hinted that Crawlers are no longer being used, one of the Intel Documents in Resistance 2's Co-op Campaign clearly states that when the Chimera broke through the Liberty Defense Perimeter, the Chimeran Battleships used Crawler Spires as well as Spinner Spires to infect the American population. It also goes on to state that the comatose bodies were transported to conversion centers by Carriers. It's possible that the Chimera managed to somehow keep the old conversion process. Another possibility is that since Resistance 2 came out before Resistance: Retribution, the idea of how Spinners came to be wasn't thought of until Retribution.
