Warp Frontier is coming to Linux and Mac! I have just now finished testing that they run on those platforms and got the Steam integration hooked up. If you're an owner of Warp Frontier already, or would like to test on those platforms please reach out and I'll get a small group going. If everything goes well I hope to be able to release on those platforms next month!
