PlanetSide 2

Doomsday: Last Survivors is a mobile-focused real-time strategy survival game published by IGG, known for other long-running titles like Lords Mobile. While it's several years old (2021 release), similar IGG games tend to maintain a stable, mid-sized userbase through aggressive marketing and frequent updates. The game's active presence on multiple platforms (Android, iOS, Windows) and social media suggests continued engagement, though likely below its peak. Not an MMO, as its multiplayer is lobby/guild-based rather than a persistent shared world.

PlanetSide 2 is a large-scale MMOFPS released in 2012 by Daybreak Game Company. Its unique, persistent world and battles with hundreds of players make it a niche but enduring title. Active support and a tight community keep player numbers modest but steady, especially considering its age. Estimates put daily active players in the low thousands, largely split across a few servers.
