Tricell Protocol

Resident Evil 4, Resident Evil 5 and Resident Evil 6 in one outbreak.

You play Resident Evil 4. The village you are standing in is hit by a three-front outbreak: the Kijuju Front (Resident Evil 5) and the Lanshiang Front (Resident Evil 6) open in turn, each one bringing its own enemies, its own campaigns and its own music with it. Nothing from those two games is shipped in this mod — it is read out of your own installed copies and used from there.

What a player gets

• Three fronts, one fight. The Village Front (RE4's own enemies, untouched), the Kijuju Front and the Lanshiang Front. The outbreak rotates between them while you play; each front holds for about 75 seconds and lands a wave of its own enemies on its own cadence.
• Every campaign the other two games have on the board. The mod reads their real stage ids and chapter markers out of your installs: RE5's ChapterEnd11 through ChapterEnd63, its stage sectors s100-s804 and its Mercenaries resources; RE6's stage set grouped into Leon & Helena, Chris & Piers, Jake & Sherry and Ada Wong, plus its own extra-mode groups.
• Every enemy family, gated on your own copy. RE5's Majini, Cephalo Majini, Duvaleria and Uroboros bodies, Butcher and BSAA operatives; RE6's J'avo (and the weapon variants RE6 names itself — Axe, Helmet, Bomb), the Rasklapanje-class and the Ustanak. A row only ever fires if your copy of that game really has it.
• Their own music. Each front's opening plays actual music decoded from that game's own audio bank (a_bgm001 and friends from RE5, bgm0100 from RE6).
• The war table. REFramework's menu (Script Generated UI) lists each front, its real folder, how many asset ids were found, every campaign and mission read from your installs, the fighters named in those files, and how many of that game's audio files are present.

Solo only. Offline, single-player.

What you need

• Resident Evil 4 (2023) — the host. This is the game Melty installs into and starts. REFramework is installed automatically by Melty.
• Resident Evil 5 — required. Read from your own install; never copied.
• Resident Evil 6 — required. Read from your own install; never copied.

Textures, models, animations, levels and audio are never bundled with this mod. The mod reads what it needs from the game folders you already have. If one of the other two games is missing, its front simply stays closed.

How it works

1. On the first Play, a small bundled helper (tricell-helper.exe) walks your Resident Evil 5 and Resident Evil 6 folders, records what real content ids they contain, and decodes a few short clips of each game's own music. It writes world.json into RE4's reframework/data/TricellProtocol.
2. A REFramework Lua mod inside RE4 reads that, opens the first front and hooks the game's own enemy spawn registration.
3. When a front lands a wave, the mod flavours one of the level's own spawn points with that enemy's resistance and parasite/revival tells and green-lights it, so the enemy keeps the game's real AI, animation and streaming.
