Been interested in "Mutated Muter's Invasion", but holding on with your purchase decision because of the game not rendering the Steam Overlay on GNU/Linux (as it's been saying in the Early Access answers on the store page)? Wait no longer! From now, whether you are using Windows or GNU/Linux, the Steam Overlay will work in "Mutated Muter's Invasion" for you, so you can enjoy the same Steam experience independently of the OS.
As a reminder, the GNU/Linux version of "Mutated Muter's Invasion" will work on UPDATED Ubuntu 14.04 LTS (it is required that libstdc++6 be updated on 14.04 LTS) or a newer version of Ubuntu. Please also remember that the GNU/Linux version of the game is 64-bit.
As another reminder, "Mutated Muter's Invasion" works with OpenGL 3.x or higher. If you have OpenGL 2.x, the game may render correctly, but this is not guaranteed.
