THE QUICK ANSWER

The official 1.0 FAQ says Tetramon is built for NPC opponents and has no near-term multiplayer plans. The Steam listing identifies the game as single-player.

What NPC duels mean

The customer waiting at a play table is an in-game opponent. Personal participation in a tournament is also not the same thing as online competitive matchmaking.

Follow the Tetramon starting guide for the actual 1.0 path to a duel.

Check mod claims separately

Before following a co-op tutorial, identify the exact mod, its original author, supported platform and supported game build. A feature shown in a modified PC installation should not be promised to console players.

This site does not host mod binaries or provide a verified mod compatibility matrix. Back up your saves, follow the author’s installation instructions and do not download a repack from an unrelated mirror.

Cross-save is a different question

The launch FAQ also states that console-to-Steam cross-save is not available. Cloud saving on one platform does not establish cross-platform save support.

Check the developer’s current FAQ before planning a purchase around transferring progress or playing with friends. The answer on this page was source-reviewed on September 16, 2026.

QUICK ANSWERS

Good questions. Clear answers.

Can I duel my friends in the original 1.0 game?

The official FAQ describes NPC duels, not player-versus-player duels.

Does Steam Cloud mean console cross-save?

No. The official 1.0 FAQ separately says console-to-Steam cross-save is unavailable.
