CityBattle: Virtual Earth is a relatively obscure team-based online shooter with science fiction themes, released in 2018. It has never attained major popularity in the West and has a very niche player base, with no publisher or developer of major repute listed. Considering its age (over 5 years), lack of major support, and absence from mainstream coverage, it's likely to have a very low but not zero daily active player base, mostly from dedicated fans.
