The Orange Box represented an amazing deal even at full price, providing Half Life 2, its expansions, Team Fortress 2 and Portal all in one place. Steam are now offering this bumper bundle of awesomeness for a ridiculous £4.25, which represents truly obscene value when you consider the sheer amount of singleplayer and multiplayer content. Portal and Half Life 2 are two of the finest games ever made (and still feel fresh today)- and Team Fortress 2 is nothing short of a multiplayer masterpiece. Remember that Mac owners will be able to get involved too! Thanks to Cuddy at Hot UK Deals.
