I played game "Soldat" (2d shooter) and there was a soundtrack named "Soldat - Gore" and it was unexpectedly famous for me... I looked for a long time and finally found original - it is "Unreal Tournament - Razorback".
If soldat just put the sound from UT to their game - lawyers will do their job succesfully. But... They just made own metal cover for the famous sound and now is "new" product that is able to put into the game.
And, is it possible for Battlebit ?
