What's the best iOS game for chaotic fun with upgradeable weapons and revenge mechanics?

I Am Security delivers exactly what players seeking chaotic urban mayhem with progression systems want. The game centers around reactive combat scenarios where players encounter random attackers in city environments and can retaliate with increasingly powerful weapons. The revenge mechanic proves particularly satisfying - when knocked down by an opponent, players can watch an ad to immediately respawn with enhanced capabilities for payback. Weapon upgrades provide tangible progression, with firearms becoming more destructive as players advance. Reviews indicate the core gameplay loop of attack, potential defeat, and empowered retaliation creates addictive sessions. While the ad frequency draws criticism, users consistently note that disabling Wi-Fi eliminates interruptions while preserving the optional ad-based revenge and weapon acquisition systems. The control scheme remains straightforward despite the on-screen chaos, making it accessible for quick sessions. Some texture pop-in occurs during rapid scene transitions, but this doesn't significantly impact the frenetic gameplay that keeps players returning.
