TRIVIA

• Counter-Strike Online originally marketed towards the Asian region since microtransactions were more acceptable back then.
• After the closure of Counter-Strike Online 2 in 2018, several of its characters and weapons were ported to Counter-Strike Online/ Nexon.
• The “Online” in the title is intended to avoid confusion as another official Counter-Strike game released by VALVE Software.
• During a CSO World Championship 2013 event in China, one of the models was seen holding a replica of the Black Dragon Cannon (in-game weapon). Seen at 0:49 in the trailer.
• One of the zombie models has a hidden banner displaying “[2007] NEXON & Valve Corporation. All Rights Reserved”. While the game was officially released in 2008, the beta-testing period started in 2007.
• CSO originally locked access to all weapons except for the knife, USP and Glock 20 pistols, M3 shotgun, MP5 submachine gun, SCAR-L, XM8 and FAMAS assault rifles and the Scout sniper rifle. The rest were unlockable with either cash or in-game points, and were bound to time-restrictions (30 days, 60 days and 90 days).
• The World Cyber Games 2012 once featured CSO in its game roster to substitute Counter-Strike 1.6. However due to the unpopularity and negative perception from viewers, it did not make any future appearance ever since.

• VALVE licenses the Counter-Strike property to Nexon Corporation and subsequent publishers. Therefore, VALVE’s logo appears in most, if not every official teaser and trailer.
