Eurofighter Typhoon takes a step away from the direction of ordinary flight sims. You are given the task of taking six different Typhoon pilots and using them to defend the shores of Iceland from the invading Russians. Each pilot has their own skills and tactics, so stacking the deck with pilots who all have the same skills could hurt you later.
Your pilots are your lifeline in this game. If one gets shot down, depending on their survival skills and where they land will determine if they make it back or not. Needless to say, the cold waters off the Icelandic coast are pretty unforgiving. If they are even more unfortunate and land over enemy territory, you can only hope they survive the interrogation long enough for an SAS team to get them out.
Eurofighter Typhoon is completely done in real time. You have to defend the small island while a war rages on around you. This is where the game greatly differs from other flight sims. The campaign system generates missions for your pilots on the fly, in reaction to the events that go on around you. Though the world situation is scripted, the real time missions are not, and letting an invasion force land could determine if you lose the war or not.
The only other mode of play is Multiplayer, which allows up to eight people to take on a handful of missions, both co-op and deathmatch. The Multiplayer mode also doubles as a quick mission mode, as you don't have to have other people playing. Instead, you can take on the missions yourself if you so choose.
