When the leviathan moves away, silent on, engines on, and start sneaking. Observe the radar if the leviathan is approaching, switch engines off, silent off, and wait. If you spot one (or hear one nearby), activate 'rig for silent'. The general tactic is: move at slow ahead, unless you know for a fact there are no leviathan class predators. Note: 'Rig for silent' continuously drains power - and with engine off, it's completely pointless, so as soon as you switch engine off, turn the silent mode off before powering it back up switch silent back on, until you're out of the encounter. And if the leviathan is anywhere farther - outskirts of the sonar or outside of it - you can move slowly if the leviathan is still within sonar range, don't use full speed of 'slow ahead', just sneak slowly where you want to go. Note - not just 'engines spinned down' but completely off - click the propeller icon.Įven with engines on, set on slow ahead, and 'rig for silent' active, if you remain immobile with the leviathan anywhere but in nearly immediate vicinity (inner circle on the sonar) you won't get attacked. Even then the damage received that way is minor and easily repaired.

The only ways how you can take damage with engines off is either the attack began before you switched the engines off (the enemy turned red on the sonar display) or you got accidentally hit by Sea Dragon's fire as it was attacking a lava lizard or such. A Reaper may bump into you and push you around, but you won't take any damage. The PRAWN is actually pretty fast once you have the grappling hook upgrade to swing yourself around with, as well as the jet pack upgrade.Ĭyclops with engines off and lights (internal and external) off is completely invisible to all Leviathan class enemies. I would take my Cyclops down deep, but would park it in a place that is safe from any large creatures, and continue to explore with the PRAWN. Personally, I like to navigate the very deep parts of the game with the PRAWN suit instead. Lastly, the sonar upgrade can aid you in pointing out creatures you can't see. The shield generator uses a significant amount power, so be sure to use it only when needed.

You may also want to use a shield generator to temporarily make the Cyclops invulnerable. If a creature is coming at you, you can launch a creature decoy to divert them away from you and allowing you to escape.

Be sure to use your cameras to be aware of your surroundings as well. You can engage silent running mode at any speed setting to further reduce noise (by 50% according to the Wiki), but it consumes power at a faster rate. The faster your speed, the louder you are, which means the further creatures can hear you. The different speeds you can select affects the amount of noise you make.
