GTA 6 developer Rockstar Games were once working on a zombie survival game set on a Scottish island, which sounds like a mixture of GTA: Vice City and legendary Arma mod DayZ. That's according to former technical director Obbe Vermeij, who joined Rockstar North in 1995 back when it was called DMA Design, and left in 2009 following the release of GTA 4. In the run-up to the GTA 6 trailer reveal next month, he's started blogging about the development of several Rockstar games, from GTA through grotty snuff film simulator Manhunt to cancelled projects such as the zombie title and Cold War stealth fest Agent.
