Valve’s Mac supported version of Steam is out, and one of their most critically acclaimed titles next to Half-Life, Portal, is being offered completely free until May 24, 2010. This goes for both the PC and Mac versions of the title.
I’ve played it as part of the Orange Box years ago, and although yes, it had it’s good puzzle solving stuff going on, it was a bit short, and too be honest, a bit boring. I mean – no guns… no enemies to use said guns on? Come on!
Still, to get a game of this calibre for free is a good deal, and worth looking into if you need a less violent FPS.
