Roller

From the Resistance Wiki

Rollers are the adult version of the Chimeran Leaper which has allowed the strain to become faster through the use of trundling locomotion.

The side effect of their advanced age means that the variant is approaching the end of its life-cycle where internal decomposition has resulted in the venting of a corrosive spray. The Rollers are known to use this spray as an opening attack on enemies, blinding them before the creature moves in for a finishing attack using its claws and teeth.

Swarms of Rollers have been known to wipe out large troop deployments in a matter of seconds.

Rollers have appeared in both Resistance: Fall of Man and Resistance 2. Rollers first appear in Bracknell, In a darker place. They later appear in several places in Resistance 2.
