Valve has today launched cult multiplayer FPS, Counter Strike Source on Mac, along with a significant update that adds new features to the game.
The new patch brings achievements and stats features into play, plus "engine updates and more". Plus Valve has also marked the occasion by temporarily slashing its price by 66% from $19.99 to $6.80, so now's the time to get involved, basically.
CS Source is a 'Steam Play' title, so if you do already own the game on PC, you now also own it on Mac too. Although if you're a PC you won't want one of those Apple things, right?
