Recently Renegade X has gone into open beta.

Here is how we are told it can be made to work in Linux:

I have attempted this myself and have it semi-working (the sound and some textures do not work correctly).
Would PlayOnLinux be able to finish the job and include an installer for this?
Ubuntu 16.04 LTS
8GiB RAM | Intel 3.20 Quad Core CPU
GeForce GTX 750 Ti/PCIe/SSE2 | Dual 4.3 (5:4 res) 19" screens
