One of the most revered PC multiplayer shooters is now available for the Mac. The Mac port of Counter-Strike: Source can be purchased exclusively through Steam.
CS:S is a SteamPlay title, so if you purchase the game for the Mac through Steam, you'll be able to play it on the PC (and vice versa). The game also supports cross-platform play so you won't be hurting for opponents. Steam's offering it at a 66% discount ($6.80 instead of $19.99) until Friday.
Additionally, Valve released an update for both versions today. It adds new achievements and stat screens and makes a number of other changes. The patch notes can be found here.
