Marrowbreach quick answer
Marrowbreach is a predator entry most worth checking around Karakorum, Root Canyon. Scan it only when you still have a visible route home, enough oxygen to retreat, and a clear reason to add the creature to your current checklist.

Location and route
Start from the closest safe landmark in Karakorum, Root Canyon, then make one pass to identify sightlines before committing to the scan. If the creature pulls you away from the marked route, cancel the attempt and return with more oxygen, better mobility, or a vehicle-supported path.
Uses and unlock value
Marrowbreach is mainly useful for threat study and deep-route planning. Record the biome, nearby plants, nearby minerals, and the tool loadout that made the scan safe; those notes are more valuable than a one-time sighting during Early Access.
Risk and scan notes
Abort if it forces you off your marked line. The safest scan window is after you stop moving, check oxygen, and confirm no larger threat is closing from behind. In co-op, one player should hold the landmark while another scans so the team does not lose the return line.
