Lobby & Difficulty Settings
Players create a lobby (single-player, invite-only, or public) and choose Easy or Hard difficulty before starting.
A gameplay video reports the session type (single-player vs. multiplayer) can't be changed after lobby creation, so players who might want company later are advised to start as invite-only or public rather than single-player. The game has no dedicated matchmaking server. The video points players to Discord or the Steam discussion forum to find co-op partners.
