Matrix Games announces the release of Armada 2526: Supernova, an expansion for Armada 2526, the sci-fi 4X turn-based strategy/real time tactics game developed by Ntronium Games. The new version adds LAN and PBEM multiplayer support along with new content. Here's a bit:

There are new star and planet types to discover, and more than 30 special features to make each star system distinctive. You may encounter tachyon storms, psychic plants, primitives or find abandoned alien technology that advances your own research. Two new races, with their own ships and special characteristics, await your discovery. Befriend them, play as them, or exterminate them as you wish.
