Announced a couple of days ago, Counter-Strike Online 2 will be adding this Big City map upon launch in Korea (date not confirmed). Sort of a take on Grand Theft Auto according to developer and publisher Nexon, there will be skyscrapers, vehicles and multiple missions happening simultaneously.
Some might feel that games such as Battlefield and Call of Duty have already done such big maps years ago, but it will certainly be a big step forward for the Counter-Strike franchise. 50 terrorists and 50 counter terrorists on the same map, it is going to be a blast.
