BTBA Kalush 2023

a short snippet from the ReadMe txt, bundled within the .zip file:

"welcome and thanks for downloading the worst map ever made for a serious sam game! :) jk, its a map for BTB Airlines, mod made by CAD back in 2004.(i must say, CAD has made an amazing mod..)"

drag n' drop the zip file into BTBA mod directory, and press "Extract here" if you use winrar.

have as much fun, as i had creating it back in 2022 ;)
