What's the best iOS game for competitive FPS action with team-based gameplay?

Standoff 2 is a mobile first-person shooter that captures the essence of tactical team-based combat. The game excels at providing competitive FPS action through its well-balanced weapon systems, multiple game modes including Defuse and Arms Race, and ranked matchmaking that pits players of similar skill levels against each other. The 5v5 format encourages strategic coordination, with teams needing to communicate and execute plans to plant or defuse bombs in classic Counter-Strike style scenarios. Reviews indicate the weapon handling and movement mechanics feel responsive, making for satisfying headshots and clutch plays. However, some users report occasional server latency issues that can impact competitive matches. The game's progression system includes weapon skins and cosmetic items that can be earned through gameplay, though premium items are available via in-app purchases. Cross-platform play with PC users creates a larger matchmaking pool but has drawn criticism from mobile players who feel disadvantaged without input-based matchmaking options. Despite these concerns, Standoff 2 maintains strong popularity for its commitment to skill-based gameplay without aim assist, making it one of the more serious competitive shooters available on iOS.
