A new update to the WC Saga site has added pictures of the latest visual effect in the mod: advanced shock waves. The newest member of the game's development team, DaBrain, has been able to implement realistic three dimensional shock waves in the Freespace 2 engine. It looks like they brighten things up quite well. One of the old style waves is pictured in orange. You can find more of their screenshots in the Saga site's media section here.
