Stormregion - best known these days for the likes of Codename: Panzers - has decided to celebrate the time of year by releasing pigs and rabbits into our homes. Which is to say that it's decided to release its old-days RTS S.W.I.N.E. for free.
S.W.I.N.E. is about the fight between pigs and rabbits, and surprisingly enough does involve tanks, artillery and a whole bunch of other modern - not to mention human - instruments of warfare. (Although, in a nod to fantasy, it doesn't involve downloading stuff off the internet and then using it to hoodwink your entire population into believing that the enemy has the ability to zap you from space using magic dragons.)
If you fancy having a go at S.W.I.N.E.'s 30-odd single-player missions, staple skirmishing and farm-tastic multiplayer, you'll need the ability to download files using BitTorrent, and you'll find the requisite download links on the Stormregion website.
