Today's Xbox Live Arcade update brings you Darwinia+, an updated version of the popular indie PC title that won the hearts of quirky strategy gamers back in 2006. The XBLA release also contains an updated version of Multiwinia, its sequel that features an online multiplayer.
You control a bunch of flat digital creatures called Darwinians, whose survival is threatened by an evil virus bent of destroying their world. You have to train them to be combat-savvy, help them repopulate and ultimately destroy the virus.
Darwinia+ will cost you 1200 of your Microsoft Points.
