1993 Space Machine is a side scrolling shoot 'em up, originally developed for the Amiga 500 as Shenandoah: Daughter of the Stars back in 1993. The developers had signed a deal with a publisher, got coverage in the popular Amiga magazine Amiga Format, but when the project was nearing completion the team split due to a series of personal conflicts.
21 years later, in 2014, one of the developers found a floppy disk with the source code in a drawer and decided to complete it and port it to PC, and put it up on Steam Greenlight. The game does not feature updated graphics, but is intended to be something of an Amiga time capsule.
The game is a traditional side scrolling shoot 'em up, and as many shoot 'em ups made for home computers of its era, it has some amount of progression. At the onset, there are four different locations to choose from and the player earns money which can be spent on new ships and weapons in-between missions. When starting the game, the player has just enough money to choose between three ships with differences in speed, shield strength and the amount of weapons it can carry. 6 additional ships become available as the player can afford them. The ship's shield strength doubles as its health bar, the shield can only cover part of the ship at any time, but can be rotated to absorb incoming fire, as it takes hits, the area protected gets smaller. The ship can not survive any direct hits onto its hull.
