Since Valve didn't make anything for 25th anniversary of Half-Life: Opposing Force, I offer you my little treat for this incredible game, which deserves even more than this. Download and install original WON menu and intro to restore the classic look of retail version of the game. Classic WON menu: steamcommunity.com/sharedfiles/f… Original Sierra, Gearbox Software and Valve intro: steamcommunity.com/sharedfiles/f…

Thanks for making this. The WON menu is amazing and I have never forgiven Valve for not including it when they ported it to Steam!
