A leaked version of DICE's upcoming war shooter Battlefield 3 has found its way on to illegal torrent sites, according to MCV.

The 9.96GB download contains the entire single player mode from the PC version of the game.

It's an occurance that is becoming increasingly more common. Leaks of high-profile games ahead of release this year have included Gears Of War 3, Crysis 2 and The Sims 3. And extensive details on Modern Warfare 3, but not the game, were also leaked this year.
