 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
