The Force Shield is one of the three special items that you need to get from the Knights on the three different planets. Each planet has lots of monsters and obstacles that you need to overcome. You will use the Force Shield to destroy the monster machine on the Ice Planet. You will then have to fight a giant tiger-shaped helicopter that drops snowballs on you. Using the force field, you can bounce the snowballs back at him to damage the helicopter.
How to Get the Force Shield
To your Rocket, head southeast to coordinates 73,83. When you arrive, you will find space sharks guarding the planet. You need to lure them into a trap. Shoot all of them to get them to follow you and then lead them to the black hole located to the north. The coordinates for the black hole are approximately 84,47. When you’re luring them away, keep them close enough to stay on screen or they will go back to guarding the ice planet. Once the space sharks have been dealt with, you can land the ship on the Ice Planet. When you exit the ship, you’ll be standing on a platform above ice water. Move from platform to platform while watching out for the flying robot fish. It’s a little tough to move from platform to platform and you will slide a bit because it’s ice. You should aim for the middle of each platform when jumping so that you don’t slide off when you land. Once you reach the last platform, jump up on the platforms to climb the mountain while avoiding the giant snow balls. Sir Gawain, the blue knight, is standing at the very top of the moountain. Talk to him and he will give you a special force shield.
