Randy Faulk, the main guy at NECA, said they're starting w/ only the Colonial Marines from James Cameron's A L I E N S.
Cpl. Dwayne Hicks & one other marine from the movie will be the first 2 in Series One of NECA Colonial Marines.
NECA is also making 4 new Warrior Aliens from James Cameron's A L I E N S. Clean, Damaged, blue highlights, & brown highlights.
Also, Sigourney Weaver is not included in the license. She has never approved of a Ellen Ripley figure or collectible to date. I believe the Mattel Dana/Zuul & Avatar character are the only 2 figures ever approved w/ Weaver likeness.
