Multiplayer: the direct answer
No. Honeycomb: The World Beyond is single-player — no co-op, no online modes, no shared world.
That is the whole answer. Everything below exists only to explain why, and to correct the search results that say otherwise.
Why it is single-player
In an older official reply, the developers said multiplayer is not planned: adding it would mean rebuilding the game from the ground up. The design backs that up — the survival loop (scanning, experiments, base research) is authored around one pair of hands. We label this reasoning HISTORICAL until the studio repeats it closer to launch; the single-player status itself is CONFIRMED by every current store page.
Correcting the search results
“Co-op survival on an alien planet”
THE RECORDWrong. Every official store page lists the game as single-player.
“Multiplayer mod confirmed by the community”
THE RECORDNo official mod support of any kind has been announced. Data gap, not a promise.
“The Xbox page lists online features — that means co-op”
THE RECORDStore “online features” refers to cloud saves and store services, not multiplayer modes.
