Car Defender

Car Defender combines idle merge mechanics with tower defense action. Players manage a circular defense track surrounded by incoming wave targets. By merging two identical level cars on your garage grid, you create higher-tier futuristic battle vehicles equipped with heavy machine guns, plasma blasters, and missile pods to automatically destroy approaching enemy target waves and boss ships.

How to play

Click and drag identical cars onto one another using desktop mouse or touch drag on mobile screens to merge them into upgraded vehicles. Drag merged cars onto defense track parking spots to begin automatic firing. Beginners often leave lower-level cars idling in garage spaces instead of merging them to free up parking slots.

Tips

• **Merge Identical Tiers:** Keep garage grids organized by constantly merging matching car levels to unlock higher DPS turrets.
• **Fill All Track Slots:** Ensure every available defense track spot is filled with your highest-tier battle cars.
• **Activate Speed Boosters:** Click the nitro boost icon during boss waves to double car firing speed for ten seconds.
