The Unrealscript VM is almost feature complete - only arrays and network conditional execution are not implemented yet.

It will attempt to load all level actors and initialize the map.

There’s also OldUnreal which patches up the original Unreal Tournament, but it’s not open source as it uses the original from Epic whereas Surreal Engine is open source under the zlib license.

It’s worth noting that Epic Games don’t support their classic games in any way now, they even entirely removed a whole bunch of them like Unreal Tournament from all storefronts.

Oh and don’t expect Fortnite to run on Linux / Steam Deck any time soon.
