Soulstorm is a collaboration of Relic and Titan Quest dev Iron Lore, which includes two new races and a new interplanetary campaign spanning an entire star system. On top of that, existing races are receiving new units - the debut of air units can be seen in one of the shots - and multiplayer is getting boosted.
Look for it in spring 2008.
