Proxima Shell Guide - Mortal Shell II

Who is Proxima in Mortal Shell II?

Proxima is part of the eight-Shell permanent roster documented by official platform material. Cold Symmetry’s official gameplay reveal identifies Proxima, The Broodseeker as a playable Shell. Mortal Shell II treats Shells as possessed warriors with their own abilities and memories, while weapons, sidearms, Seals, and Tarstones form the wider build around them.

Steam achievement “Arrival” confirms an unlock for Proxima.

How do you unlock Proxima?

Launch guides place Proxima inside the Shattered Beacon, where the Shell can be claimed from the body on the floor.

This route is launch-guide reporting rather than a publisher API response. Use it as a navigation aid, and check the live game if a patch changes an interaction, boss gate, or landmark.

What should you verify before investing in Proxima?

Read the current in-game ability tree before spending progression resources. Exact percentages, costs, cooldown-style timings, resistance values, and balance-sensitive interactions can change after launch and are more useful when tied to a specific game version than copied from an early guide.

For system context, see the all Shells overview and combat guide.
