State of Survival

Star Sonata 2 is a small-scale indie MMO released in 2018, best known for its niche, persistent online universe blending RPG and space action. While it maintains a loyal core community, its population is very modest due to indie scale, light publicity, and the passage of time since launch, which is typical for niche online games with few major updates. Its structure fits MMO criteria due to its persistent universe and multiplayer features.

State of Survival is a popular mobile strategy-survival RPG that launched in 2019 and has seen sustained marketing and content updates. These factors, along with a strong presence in app store charts and ongoing partnerships, indicate a healthy daily active player population. However, as a typical mobile strategy title, its DAU is in the low hundreds of thousands several years after launch, given natural attrition and aging in the mobile games market.
