Windows ZIP and Linux x86_64 AppImage. Both players must use this release and the same original disc. Unified cameras and Stacked lifebars are defaults; Split is experimental.
- Fixes the ICE startup handoff behind the host white screen/guest waiting, and preserves complete agreed settings in lobby START messages.
- Fixes Split Mushroom's premature elevator death plane and waits for both visible players at the latch. Destroy overhead panels while ascending: their ceiling crush is authentic.
- Preserves the partner while new room limits initialize.
- Supports offline co-op F7 save/load and F8 rewind with both players' state/resources. Netplay state jumps remain unavailable.
- Diagnostics live in
saves/diagnosticsbeside the executable or AppImage.diagnostics-location.txtidentifies the session. Quit normally and zip the complete session folder with a report. Loaded/rewound offline sessions include their exact replay baseline. - Adds separate default-off Ultimate Armor X code and Black Zero mods, usable together. X still receives armor from a capsule. Hosts choose corresponding shared co-op options.
- Resets private texture registrations/allocations between sessions.
Production checks:21 Windows /20 Linux title tests pass; packaged hidden launchers, complete room offers, netplay profile and execution identity agree across platforms. Native Windows tests cover both rosters, solo codes, warm/cold state loads, rewind, diagnostic replay and two-peer LAN controls. Private development controls are disabled. AppImage requires glibc2.38 or newer; no disc or retail BIOS is bundled.
Full Discord authorization/WAN/NAT and Linux gameplay remain additional playtesting. Exact staircase-floating and brief teleporter reports remain unqualified; intermittent co-op disappearance remains on the backlog.
