ArmA Mobile Ops (2016)

It is designed to be played on Android and iOS devices and features a single player campaign. Prior to its closure, online multiplayer features included a Player versus Player (PvP) Global Conflict and a Faction Wars game mode. Both of the latter game modes used a global leaderboard to measure player skill and ranking. Mobile Ops is entirely free to download and play but does offer premium in-app purchases. These micro transactions do not provide any gameplay advantages to players and only speed up the construction/training times for base buildings and units.
