We've talked about this very topic in our Fancast numerous times and wondered how Valve would divvy up the achievement load and how much Gamerscore the jam packed Orange Box would include. Well, we finally have our answer via our friend DaKing240 who dug up the achievement list for The Orange Box and it looks like it is being treated as one game.
The Orange Box (which includes
Half-Life Half-Life 2, Episodes 1 and 2, Portal and Team Fortress 2) will offer up the traditional 1000 Gamerscore and spread the achievements across all the included games / expansions with an impressive 99 achievement offering. And after doing a quick run through of the achievement list, it looks like the Half-Life franchise will be getting the majority of the unlockable goods with the other games still getting a respectable chunk of the Gamerscore. Go ahead, take a look at The Orange Box's achievements to see if you're up to the challenge of earning all 99 ... we dare you.
