It's not strictly a crossover, but it does take concepts from two anime: GuP and SAO:
In the near future, World of Tanks gets a Virtual Reality version... and one of the tech supports (for reasons that may include obsession to the point of insanity with World War II) traps them, Kayaba-fashion, in a scenario where all players and their tanks are in an uninhabited Europe, starting off more or less in Germany while 'factory sites' in Russia and France are spawning a steady but potentially overwhelming number of NPC tanks to hunt them down. Only by locating and destroying ALL these sites will players 'win' and be allowed to log-out.
Two years later, almost half the players are dead and most of the rest are crammed into a defensive position in the Alps under siege by overwhelming numbers of NPC tanks. On the other side, they're fairly sure only one factory site remains and a scratch brigade made up of anyone not trapped in the Alps is the last hope winning the game. All they have to do is get past the rather formidable army guarding it...
