The Epic Games Store listing, checked October 8, advertises Cross Platform multiplayer. That supports advertised cross-play availability; the wiki has not tested every platform pairing, and cross-progression is not established by that label.

October 27: new cross-play toggles

IllFonic’s October 27 Tower Farm Terror post adds PC and console cross-play matchmaking toggles. If a party cannot find a match together after this update, check those toggles first. The post does not say where they sit in the menus or what the defaults are, and Kingy has not tested them.

Quick checks

These are troubleshooting suggestions, not a guaranteed fix:

  1. Check that everyone has the current update and record each displayed version.
  2. Note each player’s platform and storefront.
  3. Identify the failed stage: invitation, party join or transfer into a match.
  4. Keep one party leader and retry the same pairing after a full restart.
  5. Save the exact error and whether the retry changed the result.
  6. Compare the symptom with dated developer-reported fixes before repeating the same attempt.

Patch 1.0.1 party-transfer fix

The September 8 launch notes report a fix for an Early Access cross-play problem that dropped party members during transfer into a matchmade lobby. This is a specific historical repair, not a promise that every current connection failure has the same cause.

What this page cannot promise

A complete tested platform-pairing matrix, cross-progression policy and universal party-failure remedy remain unknown. Storefront feature labels do not establish account requirements or successful joins for a particular group.
