Leviathans

Leviathans

The three giant predators of the caldera. Each is dozens of times longer than your sub, and each attacks only what it has noticed.

How a leviathan notices you

Every leviathan has an awareness meter. It fills while the creature can see or hear you, and slowly drains once you are out of sight and quiet. It attacks only when the meter is full.

  • Sight. A leviathan sees almost all the way round, but not behind itself. The closer you are, the faster it notices you.
  • Hearing. A moving sub can be heard from every direction, and loudest at full speed. A stopped sub is silent.
  • Point blank, it notices anything at all.

Can you outrun it?

Everything at one scale, seen from the side. Leviathan lengths are measured from the game’s models; the sub is drawn as a speck because at this scale that is what it is.
