Stellar Blade Co-op Mod — Seamless F5

someth1ngood's Stellar Blade co-op is 1.2.0 against Steam 1.4.1. Join bind is F5. Guest saves are not written — only the host disk matters. Nexus mod 4011 is a different listing; do not mix files. ## F5 join and the unused guest slot If F5 does nothing, the hook did not load or the Steam build is not 1.4.1. “My guest lost the boss” almost always means they were looking at their own unused slot. Guest gear from this session is not on disk. This is not Yui Seamless. ## F5 join on Steam 1.4.1

• Two players, own outfit / level / gear each.
• Shared enemies and bosses (~1.5× HP).
• Host owns cutscenes, QTEs and story devices.
• Camps, doors, puzzles and lifts work for both.
• One death does not reset; both down → camp reset.
• F5 menu to host, invite, leave.
• Same game build 1.4.1 and same mod version.
• Steam friends, overlay on, updates locked while you play. someth1ngood early drop (15–20 Oct 2026) for Steam 1.4.1: the friend plays in the host world with their own Eve, then leaves with what they earned. Guest save is not written during the session. ## Host disk writes, guest slot stays empty Then Files → Stellar Blade co-op. Host first; guests press F5. Guest progress is not written.

1. TrainerHub → Files → Stellar Blade Seamless Co-op → Download.
2. Same 1.4.1 build. Steam Properties → Updates → only when I launch.
3. F5 → host / join. Early development — not every quest is tested. ## Not Nexus listing 4011

Enemy HP/count multipliers in v1.2 must be set before hosting. Story can still fork on untested side content.
Same TrainerHub Files zip and the same Stellar Blade build for the whole lobby. Own session. Do not bring a trainer into this co-op. ## Stellar Blade Seamless Co-op on TrainerHub Files, not a third-party mirror
