01

Confirm the mode first

The current Steam listing presents Mortal Shell II as single-player. Do not promise multiplayer because a search query contains ‘co-op’; update this page only with first-party evidence.

02

A supported co-op mode would need rules

If an official mode appears, the useful guide will start with a meeting point, role split, revive rule, shared inventory plan, and team build. Generic ‘play together’ text does not solve a wipe.

03

Separate confirmed and requested features

Keep official features, roadmap notes, and player requests in separate sections so forum speculation cannot become a site promise.

04

The honest co-op answer

If you searched for co-op because you want to play with a friend, the answer currently stops at the platform listing: this site is not going to invent a multiplayer mode from a keyword.

When first-party information changes, the page can become a real team guide—meeting point, role split, revive rule, shared inventory, and boss route. Until then, keep those as requested features, not game facts.
