Well I tried to launch with umu on Linux but once I noticed it was Unreal Engine I didn’t get my hopes up, it ended up failing to install .NET and VC++ and all the other stupid bullshit UE can’t live without.
I’ll give it another try if you upload a Linux build, I do love me a mech game, and this one looked really lively from the clips I’ve seen you post of it. From personal experience UE Linux builds should “just work”, you just have to wait the fifteen extra years while all of the shaders compile again.
