Ambrosia Software has updated Multiwinia (http://www.ambrosiasw.com/games/multiwinia), a real-time online strategy war game for the Mac, to version 1.3.1. The new version offers some gameplay and interface tweaks and fixes some bugs.

Here's how the game is described: "Multiwinia is a multi-player real time strategy war game unlike any other. A chaotic war is raging in a fantastic fractalized world populated by bloodthirsty little stick men with a mission: follow your orders to annihilate their enemies. They will do your bidding no matter what the cost: order them to take that hill, flank the enemy or run screaming towards the flame turrets. The Multiwinians are bent on destruction, and if a few hundred of them have to be incinerated to get that flag, so be it! Multiwinia is being developed in partnership with Introversion Software, and follows award-winning Darwinia, DEFCON and Uplink."

Multiwinia requires Mac OS X 10.4.11 or later. It's Universal binary so runs natively on both PowerPC and Intel Macs.

Multiwinia costs US$19, though version 1.3.1 is a free update for registered users. A 30-day demo is available for download.
