SpecForces: Instant Adventures was to have been a West End Games RPG supplement, written by Pablo Hidalgo and S. John Ross. In Hidalgo's words:

"The WEG Instant Adventures book proved popular enough to spawn a sequel, a Lords of the Expanse edition of IA. The second sequel would be instant adventures centered around SpecForce type characters. I was in the middle of writing a story about Rebel commandos escorting an influential prince returning to his homeworld, and protecting him from Imperials and traitors."
