Arkham Multiverse

Five Batman/DC game worlds on one map. You play in Batman: Arkham Knight; the other four worlds are the ones you own, opened through gates on the map.

| World (plate) | Game | How you get there | |---|---|---| | Gotham City | Batman: Arkham Knight | Host world — this is where you play | | Arkham Island | Batman: Arkham Asylum (GOTY) | gate — launches your Asylum through Steam | | Arkham City | Batman: Arkham City (GOTY) | gate | | Gotham (Origins) | Batman: Arkham Origins | gate | | Metropolis | Suicide Squad: Kill the Justice League | gate |

Install (one click)

Melty installs the mod into your Batman: Arkham Knight folder and starts the game for you. Nothing to unpack by hand.

You need all five games installed — Arkham Knight to play, and the other four because the map and the intel are read out of your copies of them.

How you play it

1. Arkham Knight starts and a Multiverse window opens beside it.
2. Play Gotham normally (AK combat, Batmobile, everything untouched).
3. Press M in Arkham Knight any time to bring the map to the front.
4. On the map: click a world plate, then open the gate — that game launches through Steam and you play its real world, real levels and real enemies. Nothing ever closes a game you have open.
5. The sidebar lists that world's armory (every gadget read from its own files) and its enemy intel.

While you play, Batman's live position is drawn as a gold dot on the Gotham plate.

Honest limits

• One large Multiverse map with gates you travel through — not the five games fused into one seamless 3D landscape. Each world keeps its own engine, map and enemies; that is what makes the travel real.
• Suicide Squad is never modified (online game, EasyAntiCheat): the mod only reads its files, and travel launches it normally.
• Asylum, City and Origins run unmodded; the mod adds the map, the intel and the gates.
• No game files are redistributed — every game fact is read from your own installs at runtime.
