The ArmA developers imprisoned in Greece on charges of espionage have been granted bail, after spending 128 days in prison.

As reported by Eurogamer, Czech media are reporting that Greek Prime Minister Anthonis Samaras phoned his Czech counterpart this morning with the news.

Ivan Buchta and Martin Pezlar will be allowed to return home to the Czech Republic.

DayZ’s Dean Hall has expressed his relief at the news.

"Without Ivan, DayZ never would have come out; he was the guy that pushed for me to be bought over from New Zealand to work on ArmA 3, which is where I learned some of the engine interior I needed to make DayZ a success,” he said.

“He was the guy who was at the airport to meet me when I arrived, always smiling always cheerful. He was the guy who came to pick me up at the airport when the 'weight' of the success of DayZ had hit me while I was at E3.

"Not having him around, and knowing that he was in prison, has really left a big hole that has been impossible to fill emotionally. If you haven't met Ivan before, you really can't meet a more positive, strong and wonderful person to work with. Martin is also a really wonderful guy to work with, it's going to be very emotional for everyone when they are home."

The bail for each developer has been set at €5000 (AU$6,296).

The pair were arrested last year on suspicion of espionage for taking photographs and film of military installations on the island of Lemnos in Greece.
