Ruins of Tarsonis is an allied 4 player map. It is a more balanced version of War Zone, which was removed from the map pool.
The biggest downside of War Zone was that it was nearly impossible for a player to assist their ally if they didn't have a mobile army. However, with the shared choke points on this map, it's now possible to play as any race combination without obvious disadvantages. In the mid/late game, however, there are back-door attack paths leading to a player's second expansion areas, so they should be sure to defend those locations as well.
