Counter-Strike: Global Offensive Arrives for Mac on Steam
Along with Portal 2, this is the second time that Valve has launched a flagship game simultaneously on the Mac and the PC, and the first Counter-Strike release since Steam launched on the Mac in 2010.
Counter-Strike: Global Offensive (CS: GO) will expand upon the team-based action gameplay that it pioneered when it was launched 12 years ago.The Mac version has fairly liberal system requirements, with CS:GO looking for an Intel Core Duo processor with 2GHz or better, 2GB of RAM, and an ATI Radeon HD 2400 or better or a NVidia 8600M or better.
CS: GO features new maps, characters, and weapons and delivers updated versions of the classic CS content (de_dust, etc.). In addition, CS: GO will introduce new gameplay modes, matchmaking, leader boards, and more.
Counter-Strike: Global Offensive is available via Steam for $14.99.
