The co-op overload was a gameplay mechanic designed exclusively for Ratchet & Clank: All 4 One. It was activated when all available players were shooting at the same enemy at the same time. A grey reticle would then appear that would get larger and would turn red the more the players shot at the enemy. The fire-rate of weapons would also increase during an overload, and during the finishing shots, the game would go to slow-motion allowing a dramatic kill.
