Ceph energy cells are scattered around the game. They mostly can be found near Ceph weapons or in boss battles. They are often found in groups of 2-3.
When the player confronts the mind carrier in the final mission Gods And Monsters, the super charge that he/she receives lasts longer than any other. Most super charges don't last longer than a few seconds. When Ceph energy cell is active it has a glowing red cloud around it. When not active the red cloud goes away. The energy cell works like the upgrade module Heavy Armor, and slows the player down. The energy cell gives Ceph Weapons unlimited ammo while the energy boost is active.
