Key Features
- Persistent power growth: Spending points between runs makes you feel like a god. Your satellites get stronger as you grind.
- Reactive defense field: The planet takes damage if you miss. It is stressful when the screen fills with hot lead.
- Tactical ability management: Special buttons wipe the screen. Use them sparingly because the cooldowns are long.
- Scaling threat levels: The later waves are kind of unfair. You might need a few tries to survive the final rush.
How to Play
Mastering Earth Defense controls
Use your mouse to click the buttons on the left to deploy satellites. These are your primary line of defense. Earth Defense controls are snappy, but don't just spam clicks. You need to manage your energy carefully or you will run dry right when a massive cluster of rocks hits your sector.
Upgrading your Earth Defense fleet
Every enemy you blast nets you experience points. Use these to buff your stats during the round. You also earn currency for permanent upgrades after the game ends. That is how to play Earth Defense effectively. A common mistake is ignoring your special abilities on the right side until it is too late.
