Vega Prime

From publisher blurb: Vega Prime is the leader of a group of transformming robotic spies designed to infiltrate worlds by imitating the technology of native civilizations and then lay the groundword for an invasion by the Mech Centrality - a space empire of technological lifeforms that view all biological life as a cancer in the universe. Are your heroes up to the challenge of stopping Vega Prime and his squad before he can open a portal to his homeworld and establish a beachhead for an army of merciless mechanized shock troppers? (This pdf also includes art and a write-up for the workhorses of the Centrality military - the Mech Centrality Shock Troopers.)
