Forgotten Worlds is an arcade game released in 1989 by CapCom. The game was released for most computers and consoles at the time.
In the game, we play as nameless heroes. Your task is to eliminate as many "strangers" as possible. You have a rifle, a jetpack and a cover at your disposal. At the end of each level, you can visit the weapon shop and buy a better weapon for the coins you collect after killing the aliens. The action of the game moves like in many games of this genre - from the right to the left screen.
