Up Arrow To Accelerate and Arrows To Move Shoot All Asteroids! (And Don't Get Hit By One. :P) Asteroids is a space-themed multidirectional shooter arcade game designed by Lyle Rains, Ed Logg, and Dominic Walsh and released in November 1979 by Atari, Inc. The player controls a single spaceship in an asteroid field which is periodically traversed by flying saucers. (Wikipedia) Brought To Scratch By @FakePotatoTV! The objective of Asteroids is to destroy asteroids and saucers. The player controls a triangular ship that can rotate left and right, fire shots straight forward, and thrust forward. Once the ship begins moving in a direction, it will continue in that direction for a time without player intervention unless the player applies thrust in a different direction. The ship eventually comes to a stop when not thrusting. The player can also send the ship into hyperspace, causing it to disappear and reappear in a random location on the screen, at the risk of self-destructing or appearing on top of an asteroid.
