YARS' REVENGE ATARI 2600

In Yars' Revenge, your objective is to destroy the Qotile laser base, which is located on the right side of the screen behind a shield. You control the fly-like Yar, who can destroy the shield piece by piece by shooting at it or colliding with it. Once the shield is down, you will need to use the Zorlon Cannon to destroy the Qotile. The Zorlon Cannon is located on the left side of the screen and, when fired, can destroy the Qotile with a direct hit.
