Windows
Minimum: OS: Windows ME/2000/XP/Vista/7/8 Processor: 850 Mhz Pentium III Memory: 128 MB RAM Graphics: OpenGL compatible video cards Storage: 200 MB available space Sound Card: DirectX compatible sound card Additional Notes: Currently the game doesn't run properly with the default steam shortcut. Instead run the .exe directly. The .exe files are usually in their respective game folders at \Steam\steamapps\common. Combatability problems can be avoided by setting the executable to run in compatibility mode for windows XP.
