World of Warplanes, the much anticipated follow up to World of Tanks, is having its release date pushed back to 12/13 November.
World of Warplanes has been running an open beta since June.
Studio Wargaming was originally intending to release the title next week, but states that it still needs some final polishing before it is given a full release.
World of Warplanes is currently running an open beta and has been since July. The closed part of the beta started a year before in May 2012. Players taking part in the beta will have their experience points reset once the game launches.
'We are committed to releasing a great title and are doing everything to ensure that World of Warplanes gets the final polish that we believe the game needs,'
said World of Warplanes director of global operations Vlaa Belozerov. 'The extra time will allow the development team to apply some last fine-tuning to the game's balance and make sure that every feature is top-notch before launching the product.'
The engine that World of Warplanes uses is the same "BigWorld" engine used by World of Tanks, although some tweaks have been made to adapt the environment for aircraft.
Wargaming's first foray into the free-to-play market, World of Tanks, has proven to be highly successful and the title currently has 60 million registered players worldwide. Last year, the studio announced that it had generated approximately €217.9m in revenue almost exclusively from the game.
An Xbox 360 release of World of Tanks was announced in June this year that will run separately from the Windows version and is currently being developed by Wargaming West. It is currently in closed beta and its original release date was listed as summer 2013.
