About Marrowbreach

AggressiveWreck interiors

Marrowbreaches are interior-pressure predators that nest inside larger wrecks. They are slow in open water but devastating inside the cramped corridors they call home, where the walls deny most of your dodge options. They actively bite at structural plates, accelerating wreck collapse, so any interior salvage run has a clock attached. Plan the entry route before going in, place a beacon at the breach, and exit the same way you came rather than improvising in unfamiliar tunnels. Killing one inside its nest is doable but rarely fast enough to justify the oxygen and durability cost.

How to handle an encounter

  • · Disengage on first contact. Distance beats damage trade against this species.
  • · Break line of sight. Most aggressive species lose lock within a minute.
  • · Engage only with a clear oxygen budget and a planned exit.
