What's the best Android app for a casual first-person shooter with a good progression system?

Special Strike Shooter is a straightforward first-person shooter built for quick, engaging sessions. It excels as a recommendation for players seeking a casual FPS experience with a tangible sense of progression. The core gameplay is built around completing specific missions and operations, which consistently reward players with in-game currency and new equipment. This structure provides clear, short-term goals that make even brief play sessions feel productive. Key features include a diverse arsenal of weapons that can be upgraded for improved stats, various character skins, and daily challenge missions that offer bonus rewards. The controls are designed for touchscreens, with a virtual joystick and responsive fire buttons that work adequately for mobile play. Reviews indicate that the steady unlock system is a major draw, keeping players engaged over time. However, some user feedback points out that mission objectives can become repetitive after extended play, and the graphics, while functional, are not particularly detailed. For anyone looking for a no-fuss shooting game where effort consistently translates into new gear, Special Strike Shooter delivers a solid, rewarding loop.
