[CUSA08218] Serious Sam Collection Update v1.02 Fully Backported
Base:
Notes: 5.05 Backport! Tested on 5.05! Dont think 6.72+ needs a backport but if it does then use 5.05's, game is built with 5.50. Could not test the splitscreen because i cant press square on the keyboard for remoteplay lol
Enjoy
