Plutos
Atari 7800 · 1987
About this game
Plutos is a long lost unreleased prototype developed by Tynesoft for the Atari 7800, and appears to be a loose port of the ST/Amiga game of the same name.
The existence of Plutos has been known for some time, as a physical prototype has been in hands of a collector for years, but this prototype was known to be unstable and crash frequently.

The source code for Plutos was discovered in 2008 and several 7800 enthusiasts were able to get it compiled and running properly on stock 7800 hardware.
Plutos is a vertically oriented space shooter that features gameplay similar to Raiden.
The game features six different levels, each with its own unique theme and boss.
Only three of these levels are unique graphically--the other three are just color palette changes.
Plutos offers one player as well as two player simultaneous modes, selectable with the left difficulty switch.
Plutos also has features a unique weapons power-up system.
There are three different types of weapons, each of which can be upgraded up to four times, as well as an invincibility power-up.
The three different weapons are: Dual machine guns, spread gun, and energy gun.
A partially compiled version of Plutos was discovered by Curt Vendel, and thanks to the efforts 7800 enthusiasts Robert DeCrescenzo, Mitchell Orman, and Eckhard Stolberg, made playable on 7800 hardware.
It's a shame that Plutos was not released as it was obviously very close to completion and would have been a boost to the 7800 library.
About Atari 7800
The Atari 7800 (1986) was designed as a technical successor to the 2600 with backward compatibility for that console's cartridge library, but it launched years after being developed and struggled against the NES's dominance. Its brief commercial window means a relatively small original-game library, making complete 7800-exclusive titles a niche but approachable part of classic Atari collecting.
Gamevaro tracks Plutos for Atari 7800 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Plutos to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This A7800 release dates back to 1987.

Rarity & condition
No market sales have been tracked yet for Plutos — this could mean it rarely changes hands, or simply that Gamevaro hasn't recorded a sale for it yet. Be the first to add it to your collection.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
