About Forgotten Worlds

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 consists 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 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 "zennies" from defeating enemies throughout the game. The zennies are 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 consists primarily of new weapons for the satellite module, but also includes a health kit to restore lost vitality, an 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. Forgotten Worlds consists of five stages with a total of eight bosses. The player will lose if their vitality gauge runs out, but will be given a chance to continue.

Prices are per version and are not interchangeable, and neither are the reviews: conversions in this era were often built by a different studio than the original, so a score earned on one machine says nothing about how another plays.

The Sega Master System version

A one-player take on Capcom's arcade shooter, fun but easy, at a price above the typical European cart.

Forgotten Worlds began as Capcom's 1988 horizontally scrolling arcade shooter; the Master System version was developed by Sanritsu and published by Sega, and came out in Europe in July 1991 and in Brazil in 1991. It is a one-player game, and since the standard controller has only two buttons, they are used solely to rotate the character, who shoots automatically.

Mean Machines Sega, revisiting it later, called it still enjoyable but way too easy, and noted that there were not many sideways-scrolling shooters on the Master System.

What the press said at the time

Mean Machines Sega Issue 3December 1992OVERALL 62%
Joypad78%

“Forgotten Worlds is an enjoyable blasting game with plenty of action. However, it has one bad flaw; it's too easy.”

— Mean Machines Sega, July 1993

“Become a hard floating mercenary with a flying gun in Forgotten Worlds and shoot lots of things. Yes, it's a horizontally scrolling shoot 'em up. Sadly, it's spoilt by a fiddly control method and a lack of chal¬ lenge. There are much better shooters than this on the Sega.”

— Mean Machines Sega, December 1992

Undated scores are from the review table in the game's Wikipedia article, limited to reviews of the Sega Master System version.

The Sega Genesis version

An enjoyable but easy Genesis shooter built from Capcom's arcade game, priced a little above the middle among US carts.

This is the Genesis / Mega Drive version of Forgotten Worlds, a horizontally scrolling shooter that began as Capcom's 1988 arcade game. Sega produced the home conversion, which came out in Japan in November 1989, in North America in December 1989 and in the PAL region in 1990.

To mimic the arcade controls, the A and C buttons rotate your character in either direction while B fires. Mean Machines called it a good-looking one- or two-player blast with plenty of action, easy to finish on the easy setting but challenging on the harder one. In a later look back the same magazine found it still fun but said there were loads of better shooters by then.

Before you buy

Among US carts it sits above the median. The European cart usually costs noticeably more than the US one, and the Japanese Mega Drive cart usually costs more than the US one, with a different cartridge shape from a Western console's slot. Sega Retro lists the game as incompatible with the six-button pad, so keep a three-button pad handy. It is a cheap-tier game with no per-game fake concerns; just confirm the cart works before paying.
