1994 Sci-Fi: Star Brigade Pilot v4 (Star Brigade)

Includes: helmet with internal rebreather, handgun, string, weight (2), sonic climbing backpack, missile (2)

Several of the 1994 Star Brigade figures came with unique action pack like accessories. Sci-Fi's "Sonic Backpack" featured a hook at the top for sliding (see below), a flip down gun and a flip down spring-loaded missile launcher complete with two black missiles. Fun stuff!

Sci-Fi came equipped with two black climbing hooks and a loop of string. See sliding instructions on the back of his card, below.

This "design sheet" was also known as a "control sheet" and was created by R&D to guide the sculptors as they molded the figure.
