Description Level 1
When the first few waves of enemies come rushing at you, choose the straight laser as your weapon to take them out one at a time. Now quickly switch to the round vulcan missiles when the enemy ships encircle you. Dodge between the asteroids, and destroy the ones that shoot at you. To defeat the mid-level boss, avoid his fire and shoot him right in the center. Again, for the next wave of enemies, your best weapon is the straight lasers. This weapon is also effective for blasting through the purple webs in your way. When you reach the giant spider, switch back to the round vulcan and hit him directly in his blue eye. Avoid the bullets and mini-spiders as you fire away.
Description Level 6
You are now approaching the Alien Fortress, so have your trigger finger ready. Start out by flying low to take out the cannon on the bottom of the ship, and then fly around to blast the two on top. Switch to the round vulcan, shooting all of the barriers to make them drop down. Take out the mid-level boss by blasting him right in the eye, while you avoid his two pet drones. Inside the enemy fortress, your best friend is your Needlecracker laser. Have it handy while you zip around the enemy fire, on your way to the final battle with the Alien Emperor. When the Emperor sends out the group of rotating rocks, keep blasting away with the Needlecracker laser while you follow the rocks around in a clockwise motion. It is very important that you keep firing away to the right, hitting the creature directly in the center. When the boss sends the group of Axelay clones at you, move towards the upper left part of the screen and keep firing. The rest of the battle is all a lot of fast dodging, while you keep shooting away the Emperor as he s on the run. Move around top to bottom, and weave in between his lasers as you nail him with the Needlecracker laser. This part sounds much easier than it is, so keep practicing until you destroy the final boss.
