"Slow news day, eh?" Only in your underpants, loser. For all four of the Mac gamers who read RPS, this is a very, very, very, very, very fast news day. Because one of last year's best games, XCOM: Enemy Unknown, has arrived on their shiny, overpriced, hard to upgrade PCs-with-different-software.
It's available via the Mac App Store or direct from porters Feral Software (they're a bit bitey), though a later Steam release hasn't been quite ruled out.
Firaxis' remake of the olden DOS strategy title is the kind of game that seems rather appropriate for Macs - not too graphically demanding, a reasonably comfortable play on trackpad, and the plot concerns brainwashed people slavishly following the directives of a heartless inhuman overlord, so Apple fans will be on familiar ground.
The DLC to date is included, hence the 'Elite Edition' subtitle, and they want $50 for it. Alternatively, install Boot Camp and buy the PC version for much less, as well as whatever other PC games you're interested in.
