The main objectives in Crash of Cars are to collect crowns while destroying other players' cars. Players can also complete various missions to earn rewards and upgrade their vehicles for better performance in the game.

You unlock new cars by collecting enough crowns and leveling up. You can also find cars in chests that you earn through gameplay, allowing you to expand your collection and enhance your gameplay experience.

Power-ups are special items that give you advantages during gameplay, such as increased speed or shields. You can pick them up randomly on the map. Once collected, they automatically activate to help you during battles.

To excel in multiplayer mode, consider these strategies: 1. Choose a well-balanced car that suits your playstyle. 2. Always prioritize collecting crowns. 3. Use power-ups strategically to gain advantage. 4. Pay attention to the map layout to avoid obstacles.
