One of the biggest multiplayer shooters to grace the PC in the last year is Unreal Tournament 2004. Although it is well known as a great first person shooter, the 2004 interation includes varied gametypes including a space borne assault. A larger starship is attacked by fighters, and then the ship's crew ends up defending against boarding parties in a more traditional Unreal setting. Quite a few reviewers have picked up on this mode's similarities to Wing Commander.
GameSpy: Starting in the cold vacuum of outer space, the map comes complete with controllable spaceships offering Descent-style freedom of movement and some Wing Commander-type dogfighting.
IGN: Even more impressive, another map starts with both teams piloting spacecraft for a Wing Commander-style dogfight, the attacking team attempting to board a giant Skaarj mothership. Once the ship is boarded, the action switches on-foot.
IGN: The combination of initial Wing Commander-like dogfights with more traditional troop assault worked very well, and apart from a few control and targeting niggles, it's a smooth transition from flying to running.
ActionTrip: There's a space-based Assault map called Mothership, which thrusts you off into orbit and allows you to challenge other players in classic Wing Commander-style dogfights.
PalmBiscotte: Chars, jeeps, camions, speeders, chasseurs, bombardiers, chasseurs spatiaux pour les bases dans l'espace (et là on dirait du Wing Commander en plus beau), il y a le choix. Ce mode est génial,It seems like there's at least a little Wing Commander nostalgia on the part of the gaming journalism community. If you're both an FPS and space combat fan, this one is a great match. With the associated mod tools already available, Unreal looks ripe for a good Wing Commander mod if you ask me. Here's a few example shots for good measure.
