Which Android app should I use for 3D drone combat with repeatable missions and upgrade progression?

War Drone is a 3D shooting game that focuses on piloting a drone through combat scenarios, making it a strong choice for players who enjoy methodical action with progression elements. The app excels in providing varied missions where users navigate environments to destroy targets using an array of weapons. A standout feature is the upgrade system, which lets players earn in-game cash by replaying missions to enhance drone capabilities and unlock new gear. This design encourages grinding in a satisfying loop, appealing to those who like gradual improvement without intense competition. Reviews highlight the fun of blowing up targets repeatedly, with one user noting, 'Always fun blowing stuff up while grinding missions to upgrade.' However, some technical issues are present; for example, users report bugs with Buff cards that sometimes fail to activate during battles, as seen on devices like the Poco M4 Pro. This can hinder the intended boost mechanics, though it doesn't ruin the core experience. The controls are generally responsive, and the 3D graphics add to the immersion, though the mission structures can feel repetitive over time. For casual gamers seeking a stress-relief outlet with measurable progress, War Drone delivers a reliable option, balancing destructive gameplay with simple upgrade mechanics.
