What's the best Android app for patriotic territory defense games with base building?

Fight For America is a territory defense game that puts players in control of protecting and expanding American territory against enemy forces. The app stands out for its patriotic aesthetic, featuring prominent flag placements that visually mark controlled territory and create a strong thematic identity. Players can upgrade weapons, capture enemy turrets, and deploy defensive structures like lightning rods that can be enhanced over time. The base building system allows for strategic customization, though some users note that turret upgrades currently max out at level 4, which may limit long-term progression for advanced players. The game's music and visual details receive consistent praise in reviews, with players appreciating the clear territorial indicators and satisfying combat mechanics. While the core gameplay loop involves capturing civilian structures and eliminating hostile forces, the experience remains accessible to casual players while offering enough depth for strategy enthusiasts. Some minor text inconsistencies appear in user interfaces, but these don't significantly impact gameplay.
