Forgotten Worlds

Forgotten Worlds, titled Lost Worlds in Japan, is a side-scrolling shooter by Capcom, originally released as an arcade game in 1988. It is notable for being the first title released by Capcom for their CP System arcade game hardware. Forgotten Worlds consists of nine stages each with its own boss. The player will lose if their vitality gauge runs out, but will be given a chance to continue.

Forgotten Worlds can be played by up to two players simultaneously. The player controls a flying muscle-bound soldier armed with a rifle with unlimited ammo. The Player 1 character is equipped with a long-range automatic rifle, while Player 2 has a short-range wide shot. The controls in the original coin-op version consist of an eight-way joystick for moving the character in the air while flying and a unique rotatable button known as the "roll switch". Rotating the switch left or right allows the player to adjust their character's aim in one of sixteen directions, while pressing it causes the player character to shoot his gun. This allows for the player to move their character anywhere while keeping their aim in one direction. Pressing the switch rapidly will cause the character to perform a "megacrush" attack which will destroy all on-screen enemies, but at the expense of a portion of their vitality gauge.

The player character is accompanied by a satellite module orbiting near him that will provide backup firepower every time the player fires their gun. Like the main character, the satellite can also be rotated with the roll switch. Rotating the character while firing will only rotate the aim of the satellite, while rotating the character without firing will not only rotate the satellite's aim, it will also move its relative position around the player.

The player can obtain blue-colored coins known as Zenny from defeating enemies throughout the game. Zenny is used as currency to obtain new power-up items from shops located at certain points in each stage. When the player enters an item shop, they are given a choice of the items available and a limited time to make any purchase they wish. These items consist primarily of new weapons for the satellite module, but also include a health kit to restore lost vitality, armor that allows the player to sustain additional damage, and even tips on how to defeat the boss awaiting at the end of the current stage.

It was ported to the Sega Genesis in 1989 for Japan, Europe and the United States, and it was ported to the TurboGrafx-CD in 1992 for Japan and North America. In Europe, it was ported to the Amiga, Amstrad CPC, Atari ST, Commodore 64, ZX Spectrum in 1989, and to the Sega Master System in 1991. In North America, it was ported to PC/AT compatibles in 1991. The arcade version was later included in the PlayStation 2 and Xbox software Capcom Classics Collection (2005), as well as the PSP's Capcom Classics Collection Remixed ( 2006 ). The Genesis version was released on the Wii Virtual Console in 2008.
