Focus Home Interactive announces an OS X edition of Wargame Red Dragon is now available, offering cross-platform play with the Windows and Linux versions of Eugen Systems' real-time strategy game, as the Linux version was released to little fanfare a few weeks ago. They also announce a weekend sale on Steam. Here's the deal:

Wargame Red Dragon launched a successful worldwide invasion on PCs last April and on computers with Linux just over a week ago, and we are thrilled to announce that the latest episode of the spectacular RTS series created by developers Eugen Systems is now available on Mac!

Players can now therefore download the full Mac versions of Wargame Red Dragon on Steam and from the official store. As multiplayer mode is compatible across all platforms, Mac players will be able to compete against or team up with the many players already on PC and Linux!

Owners of Wargame Red Dragon on PC can also download the Mac and Linux versions of the game free of charge to a compatible machine, and the new Mac/Linux players can also download the PC game!

And there's more good news: Wargame is the Weekend Deal on Steam! From today until Monday, June 16, you can buy Wargame Red Dragon at an amazing 33% discount, while the price of the new Wargame Franchise Pack, which now includes all 3 Wargame games, has been slashed by 40%. AirLand Battle and European Escalation, for their part, are both enjoying a 66% discount.
