Intended for those who wanted a multiplayer option in the original X-Wing and TIE Fighter games, but also a downfall.
There is no real story in X-Wing versus TIE Fighter, instead the game focuses on the multiplayer aspect. This is a massive flaw in design, though; since not everyone plays multiplayer and since there is no dedicated server list it can be a hassle to find someone who wants to play. Without multiplayer, you can play against the AI in training exercises, melee, tournament and battle matches but since the scenarios were intended for multiplayer they are not as satisfying against the AI even though it is fairly good.
Mechanics wise, XvT plays exactly like its predecessors. You have to manage your laser, shields, and engine levels depending on your situation, and switch between weapons. Since XvT is fast paced (especially melee) you also have to constantly be watching your back - doubly so now since the AI likes to spam advanced concussion missiles. Still, the great tactical gameplay is as sharp as ever despite the focus on multiplayer.
Graphically XvT isn't too impressive these days; though for its time they were fairly good. 3d models, and detailed textures brought the starships and starfighters in the Star Wars universe to life. The audio is pretty good, the classic Star Wars sounds are present, and there is quite a bit of voice acting including radio chatter that makes your wingmen feel more alive even if they are just AI. The classic John Williams score is constantly playing in the background to help immerse you in the Star Wars setting.
X-Wing versus TIE Fighter is a fair attempt at bringing the classic X-Wing and TIE Fighter gameplay into a multiplayer environment. Unfortunately the focus on multiplayer, and lack of a single player campaign also brings the title down significantly, and this was only slightly fixed in XvT's expansion. Is it worth playing? Sure, it offers more multiplayer options than its successor X-Wing Alliance, but if you're looking for a great single player game give X-Wing versus TIE Fighter a pass.
