Actually that;'s a big if. Developer (Elhoim/Oscar) said:
Hey guys, the thing is quite simple and has nothing to do with either Linux guys asking or not buying the game.
The guys at Torque3D.org are working on a port. They made good progress, but it's not finished still. If they manage to complete it and it's not extremely hard to port the game, we'll definitely do it, no matter if the Linux/Mac guys buy the game beforehand or not.
Now, if you want to continue arguing, I won't restrict your free speech liberty :) [/i]
However, the game works on Linux perfectly, I've had no errors so far (once I've run the winetrick command).
It works on my machine (i5 4670K, Radeon R9 270 X, 8 GB RAM Goodram) and on Lubuntu (using GOG version for that) I only installed Wine + typed the command "winetricks d3dcompiler_43" and it worked like a charm (without that command the game would run to menu but after clicking on a new game there was an error). And FYI I'm a total Linux noob, I use Linux only to make bank transfers, that's the first Windows game I've ever installed on Linux (I've run 1 or 2 games before but never installed one - besides AoD). Another proof that AoD is better than Underrail.
And there's always an option to run the demo and check for yourself.
