"Counter-Strike Online 2 is fully developed by Nexon Corporation of South Korea with the basic of  Counter-Strike: Source by Valve Corporation. It was stated to run a closed beta test on 16 November 2011 and open beta test on June 2013. The game was successfully ended the beta stage on December 2013 and now running on its own."

When you play CSGO, the whole game mechanism is different. CSO2 was developed before CSGO was released, so Valve wouldn't want Nexon to simply use its recent engine.

UI and gravity mainly that makes it more of a 2010 engine.
