While I go through my links.. I lol'ed at BoD.. that's so true bro.. craptastic lmfao
damn graphics sucked ass and we thought they were so awesome at the time...
I have it for my PC as well... play it on my n64 emulator from time to time..
lots of people didn't like Perfect Dark.. but I loved it..
It looked far more realistic and also had the company Rare involved in it..
Oh here we go.. the link
GoldenEye: Source BETA 1.0 (.EXE Installer) for Half-Life 2 Download - Mod DB
and here's the official site:
