+## T6 Zombies (Black Ops II)
+
+Choose **Black Ops II (T6)** in Deploy new server. T6 uses `t6_zombie_<slug>_<lobby>`
+IDs, its own saved Plutonium keys, `PLUTAINER_GAME=t6zm`, and
+`configs/dedicated_zm.cfg`. Existing T5 deployments and environment settings
+keep their current paths. API clients can send `game: "t6"`; omitting it selects T5.
+
+Before the first deployment, populate the Docker volume `t6_game_files` on the
+Komodo host with your Black Ops II game files, including the DLC maps you intend
+to host. Set `PLUTAINER_T6_GAMEFILES_VOLUME` to use another volume or an absolute
+host directory. It is mounted read-only at `/home/plutainer/gamefiles`.
+Plutainer supplies its runtime and config seeds, not the base game files.
+Use a Plutonium server key created for **T6 Zombies**.
+
+Server state defaults to `/root/zombies/t6`, or the sibling `t6` directory beside
+`SERVERS_ROOT`; override with `T6_SERVERS_ROOT`. Electric Cherry and the Komodo
+host must see this directory at the same absolute path. The supplied Compose
+mount already covers both games. GSC files go to
+`runtime/plutonium/storage/t6/scripts/zm` (no `raw/`), and game logs use
+`logs/games_zm.log`. Optional overrides are `T6_REL_DEST_SCRIPT` and
+`T6_CONFIG_TARGET_FILE`; a custom config filename needs a promoted baseline or
+a file supplied at that name, since Plutainer seeds `dedicated_zm.cfg`.
+
+The catalog includes the classic maps, Survival, Grief, and Turned selections.
+Rotations use `execgts <ruleset>.cfg map <engine-map>`; Plutainer seeds the required
+`storage/t6/gamesettings` files. Keep seeding enabled, including with a promoted
+baseline. Town, Farm, and Bus Depot share `zm_transit`, so EC keeps their selection
+in `map_slug` through creation, beta, promotion, and drift repair. Map-scoped
+artifacts target the engine map and therefore apply to all its variants.
+Creation health checks verify the engine map reported by RCON; this does not
+independently verify the start location within that map.
+
+Both games share the fleet's port allocator (`SERVER_PORT_MIN`/`SERVER_PORT_MAX`)
+to prevent collisions. EC explicitly sets `PLUTAINER_PORT`, so T6 need not use
+its upstream default of 4976. Forward the allocated UDP ports. Use a current
+Plutainer v2 image: EC relies on `PLUTAINER_RCON_PASSWORD`,
+`PLUTAINER_MAP_ROTATE=false`, and extra arguments loaded after the main config.
+Current Plutainer automatically whitelists the Docker gateway for T5/T6 RCON;
+an admin client on another host needs its address allowed in the server config.
