The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necesary, capitalization should be fixed. For more information, see the forum.
Electro magnetic pulse or EMP for short could be harnessed by the Combat Bots (or Ratchet in co-operative play) and it was used to deactivate forcefields and to take down Landstalker shields. Ratchet would often encounter electrified floors or shielded opponents on the battlefields of the DreadZone campaigns. When that happened, Ratchet should have his bots throw one of these grenade-shaped pulse charges at his shielded opponents. Just one of these would temporarily disrupt a device's power supply, bringing force shields down or stopping the electrical activity within a machine. You should press the left directional button to use the EMP.
