The game is really great and fun. The only drawback: The game sometimes crashes and a patch is currently not in sight. For the English. Version There are unofficial patches, which should make the game more stable. The Germans out in the cold. After 10 to 20 min. there are always a crash.
Edit: To use the engl.beta patches of the Graviteam page, you have only its German version to the English. Patching language. There is also a message on the forum.
