Walkthrough
The level starts with Brown Asteroids and Ship Upgrade Canisters orbiting the planet. These new asteroids are super-tough, and Impulse or Rocket is recommended to break through them. Swarms of Blue Enemy Spaceships will fly in. They are already intense at the beginning of the level. Some Red UFOs will mingle with them. Halfway through the level, Green UFOs will start moving in, and so will a group of fast Green UFOs. Target these first. Soon after, a massive wave of fast Green UFOs will enter. Don't lose your ammo as you target them. A third and smaller group of Green UFOs will swarm in. Destroy them before taking out the remaining enemies.
