Alien Invaders - Plus!

Alien Invaders - Plus!, known in Europe as Videopac 22 - Space Monster, is a 1980 fixed shooter video game developed by Ed and Linda Averett for the Magnavox Odyssey² also known as the Philips Videopac G7000. Similar to Space Invaders, the object of the game is to destroy all invading aliens while also avoiding enemy fire. It was published by Magnavox and Philips and was later rereleased for the Philips Videopac+ G7400. It reviewed favorably to Space Invaders with some critics considering the starring space monster, The Merciless Monstroth, to be a more interesting adversary. However it was criticized for only having one gameplay mode, contrary to the game's packaging.
