Developer Seed Studios has responded to feedback and enhanced Under Siege appropriately.

The update is a response to feedback from the game's release last year — and is undeniably comprehensive. New features include: an enhanced playercount in local and online multiplayer; antialiasing in both 720p and 1080p resolution; better checkpointing and rebalanced difficulty; and general performance improvements.

The update also enhances Under Siege's online netcode, with four new multiplayer maps added to the roster to keep things fresh.
