Diablo Splitscreen
Diablo for up to four players on one screen, each with their own controller and inventory.
A DevilutionX fork targeting one to four controllers on a shared screen: independent inventories, spells and merchants that never pause anyone else. Linux, Windows and the Steam Deck.
You need: your own Diablo data file (DIABDAT.MPQ)

Diablo Splitscreen v0.1.0 (test build) preview
2026-10-16 · on GitHub
Test build — the first playable slice of couch co-op. A second controller joins an offline game and plays its own hero on the shared screen while pad 1 keeps every normal control. Pad 1's inventory, character sheet or spellbook never stops the other player.
How to play: start Multi Player → Offline, create a game, press any button on pad 1, then press Start on a second controller. Guest controls: stick/D-pad walk, A attack or pick up, X cast, Y next spell, B drink a potion. Full details and limits: docs/LOCAL-COOP.md.
Known limits of this build: guests are not saved (they play a read-only copy of another saved hero, or a new one), have no inventory or shop yet, follow pad 1 between levels, and the camera follows pad 1. Tested with virtual controllers only — please try it with real pads (and on the Deck) and report what feels wrong.
You need your own DIABDAT.MPQ (or spawn.mpq for shareware); no game data is included. Linux and Steam Deck: unpack the .tar.gz and run diablo-splitscreen/diablo-splitscreen.sh (it starts the bundled AppImage; needs glibc 2.38 or newer, e.g. current SteamOS or Ubuntu 24.04). Windows: unpack the zip and run diablo-splitscreen\devilutionx.exe. This build sends an anonymous report (version, platform, "fatal error"/crash signal — nothing else) if the game fails; set DEVILUTIONX_NO_REPORT=1 to turn that off. No automatic updates yet. Not an official DevilutionX release; based on DevilutionX under its Sustainable Use License.
