When it is fitted, a button for activating the shield is added to the right-hand side of the HUD that appears when the player is controlling the Cyclops. The button toggles the system on and off, and it will remain in the selected state if the player stops controlling the vessel. When it is on, the viewing window will be covered by translucent tessellated triangles which pulse with light from time to time.
When activated, the shield makes the Cyclops invulnerable to damage from any source including moving below its current Crush Depth.There is an instantaneous drain of 50 energy from the Cyclops' Power Cells on activation, and thereafter power is drained at a rate of 50 energy every 5 seconds (10 energy per second) until the system is manually deactivated or the Cyclops runs out of power.
Any creature that touches the Shield while it is active will be repelled as if struck with the Survival Knife or a similar weapon, swimming away a significant distance before being able to re-approach. This renders it particularly useful in dealing with Lava Larvae, as any number of the creatures can be instantly detached from the hull without having to leave the vessel.
