[2] PROJECT-X (REVISED ED.) is a slightly enhanced version of PROJECT X, and was released by Team 17 at a budget price. Release of this enhanced version was mostly prompted by customer feedback that the difficulty level of the original (particularly level 2) was too high. Enhancements include:

- Inclusion of a rookie mode allowing players making easier to progress to later levels

- Starting the game with a better ship

- Shortened levels

- Removal of some extremely difficult passages of play from game levels

- Reducing the amount of disk swapping by fitting the game on 3 disks instead of the original's 4 disks
