Finished the game Portal last night which comes as part of the Orange Box along with Half-Life 2 and Team Fortress 2. Great stuff..."innovative" as they say. No shooting...at least, you don't do any shooting -- you do get shot at, though. It's more of a puzzler..sort of. Tough to say too much without giving away any spoilers. There's a trailer at the link above. Mellow game, subtle humor with the level of challenge that makes you want to go for just one more level.

Below the fold are mega-spoilers -- video of the final boss fight (Youtube doesn't do justice to the actual look of the graphics, of course) as well as the best end-game reward of any game I've played yet -- instead of a simple final cut-scene and credit roll there's a very catchy song. The guy who wrote it's made quite a phenomenon for himself.

The boss fight:
