The Independence Day VSWAP (not to be confused with the actual Independence Day mod by the same author) is a graphic replacement patch for Wolfenstein 3D released by Officer-Michael John on the Fourth of July 2015.
It's a Wolf 3D supplement. July 4 was the occasion of this supplement. Only VSWAP file in it. Will be required for a Wolf 3D full version.
