Cosmic Avenger  The game was ported to ColecoVision as one of its launch titles in North America when the system was released in August 1982. Versions for other platforms were in development and advertised but neither were officially released. The ColecoVision port proved more successful than the arcade original, garnering mostly positive reception from critics who praised the action, visuals, and sound effects. "Cosmic Avenger" is a horizontally scrolling shoot 'em up game reminiscent of "Scramble", "Super Cobra", and "Vanguard", where players take control of the Avenger space fighter craft with the main objective of earning as many points as possible by fighting against enemy alien forces, while guiding it across a scrolling terrain and dodging obstacles along the way. The joystick accelerates, decelerates, moves up, and moves down the ship, which uses a laser and bomb to destroy defenders, anti-aircraft missiles, tanks and UFOs. The ship is also equipped with a radar that allows to see incoming enemies within its range. In addition to the single-player mode, the game also features a two-player alternating mode, where each player takes their turn after one player has been defeated by enemy fire. The game is divided into three sections, each with a different style of terrain and different obstacles without an intermission between each section, as the game simply scrolls into the new terrain seamlessly. Unlike "Scramble", "Super Cobra" and "Vanguard", the ship does not rely on fuel that constantly depletes and needs to be replenished, allowing players to solely focus on the enemies. The enemies in the game exhibit their own behavior with their patterns and can also act in a stupid manner such as crashing into each other. When progressing further into the game, the difficulty increases with enemies acting more aggressively and firing at a much more faster rate. On occasions, an X station appears and if the players manage to destroy by timing their shot, it can destroys all enemies caught within its blast radius, awarding a high score as a result. In addition of being able to fire against enemies, players can also counterattack enemy fire from tanks. Speed can also affect bombs before dropping them against enemies. If the player's ship is hit by enemy fire, crashes against the terrain, enemies or any explosion radius, a life stock is lost and they will be respawned into the nearest checkpoint reached but once all lives are lost, the game is over unless players insert more credits into the arcade machine to continue playing, which forces to restart from the beginning. "Cosmic Avenger" was first released in arcades by Universal on July 1981 and became one of the first titles with forced horizontal scrolling alongside the earlier "Scramble" by Konami.
