Special bundle merges first, second games
As promised yesterday, Valve has launched the Mac version of Left 4 Dead 2, its zombie-themed first-person shooter. To promote the game though the company is now also offering a special discount, pricing the title at $6.79 instead of a standard $20. A free expansion, The Sacrifice, has been made available simultaneously.
Valve is additionally selling the original Left 4 Dead for $6.79, and a bundle of both games for $10.19. These options are featured only in the Windows section of the Steam store however, and the Mac version of L4D1 will only be ready later this month. Buying Windows versions of Steam games entitles people to free Mac downloads, if a Mac version of a game exists.
