Q: Hello, I have a trouble with the Linux version Metro: Last Light. I'm running Debian Sid... the game will not start... black screen.. instantly die.
A: We are very sorry but unfortunately your system doesn't meet the games system requirements. Your Linux OS is not officialy compatible with this game. Metro Last Light requires Ubuntu 12.04/13.04.
upd: Дебиановод продолжает нагнетать и капитанить:
Even though it doesn't specify that it is completely unsupported on other platforms, if you are not running those specific distros, you will get zero support from them whatsoever.
It is not confirmed whether or not they'd provide support if you were running a different video card than the 2 specific ones listed.
Just be aware before you purchase it.
