V4 is a cross-platform (mobile/PC) open-world MMORPG published by Nexon, originally launched in 2019. While it launched with significant interest, most mobile MMORPGs see sharp declines after the first couple of years unless they maintain strong live ops or expansions. Nexon is a major publisher, which helps its retention, but V4 is now a legacy title, likely only holding a dedicated niche audience, mostly in East Asia. Estimated around 20,000 daily players globally.
