Just to re-iterate what is stated in the description — these are the original levels using the original textures from the game. The purpose of this alpha is to rebuild all the levels 1:1 and be able to complete all the objectives necessary to finish the game. There will be many more updates, please stay tuned :)
А то я тоже удивился, какого хрена их версия ничем не отличается от System Shock: Enhanced Edition
