Today the Halflife "Orange Box" went on sale. It is available for Windows, Xbox 360, and soon Playstation 3. It retails for $49.95 and can be picked up just about anywhere.
It contains:
Halflife 2 Halflife 2: Episode 1 stand alone (HL2 not required) single player storyline that follows HL2 and improvements to the steam "source engine".
Halflife 2: Episode 2 add-on that picks up gordan freeman's (you) storyline after the events of episode 1.
Portal Stand-alone first person perspective puzzle game where you use a "portal weapon" to travel. (ie firing the weapon on teh floor, and also a wall, then jumping through the portal you made in the floor would make you immediately appear at teh portal in the wall where your momentum of falling would move you in a direction relative to how you entered the first portal). This game sounds pretty neat to me. for a few minutes anyways.
Team Fortress 2 there is a thread regarding this game in the forums. it looks like what could be the most fun FPS to date ( IMHO ).
