What you do is either buy this figure as is or don't. While HT is notorious for putting out better versions of figures, I think with ALIENS, it's safe to say, the version they put out from each film is all you'll get, they did Grid from AVP but I think that's unique enough, and a horrid repaind of ALIENS, but that wasn't an improved second release, just a repaint, and just the one Alien 3 and AVPR. HT takes one swing of the bat with Aliens and whatever sort of hit they get, they settle for it, they don't step up to the plate again to try and best it. They've had several Alien figures and enough available reference material to have done the best they could with this figure, they even published in their newsletter that they felt it was the best Giger Alien figure you could get, so if they didn't do more with this one than they did, I think it's safe to say that's it, they're not going back and improving this, they had a chance to do it right and didn't.
Thankfully, HT seems to only do the updated versions of figures for new movies where the first one is rushed to be out for film release and they don't have all the reference and facts they need to make a solid figure the first go around. Anything based on older properties, it's one and done with them.
