There are also some files that are making calls to Windows libraries. The original Swarm SDK makes it evident that it was written primarily for Windows and a lot of things that Visual Studio would let you get away with become issues with Mac/Linux compilers. I've been taking a stab at shoehorning the Swarm/Reactive Drop SDK into Source 2013 SDK. The most promising solution at this point would be that someone at Valve regains interest after the release of Reactive Drop and decides to do the port. I hope this helps everyone who wants to go down the same rabbit hole. They've been quite helpful towards mod developers who want to release on Steam, but also really secretive about their terms. Basically 1., but binary patching gets replaced with legal risk.Īsk for a custom license. Still, we'd need to reverse engineer our own SDK and that's a ton of work.īackport everything to the leaked Source 2007 code. I have some doubts they're going to be able to run Alien Swarm, but maybe it's worth further investigation.

All that's left now is Portal 2 and Left 4 Dead (2). Anything based on Orange Box is out as well, like explained above. Dota, CS:GO are out because they're Source 2 and something in between 1 and 2. I found this reddit thread speculating how the Source branches developed. Hack together an SDK for one of the more 'recent' Valve releases. We'd have to backport 6 years of engine development and patch the binary. Lacks all the features that were implemented after HL2. We don't just need a game DLL that runs on Linux, but also an engine. I recently looked into doing a community port, but it doesn't look like that's possible.
