>>7377487if you get the bonus face and shield edges, pull straight down when removing the currently-attached edges from the chest shield, do NOT wiggle it trying to free it.
If you intend to remove the thigh-covers from Hun-gurr, either sand away some of the peghole on the thigh covers or the peg itself to make removing them easier, just do it in small increments to make sure you don't shave too much off. If you don't, it can prove a bit difficult to remove the thigh covers after applying them.
the handles that fold out from the various parts of the set to repurpose them into weapons have a tendency to pop off, so be careful while doing so because they can and will go flying if they do. I don't bother with this aspect myself.
You have to remove the dragon heads when attaching and detaching whatever limb bots you're using as legs. This isn't really a problem, just it'll SEEM like you can attach them without removing them, but trust me, it's not a good idea.
Sinnertwin is really the only bot that can be used as a leg without any sort of changeups from how Abominus combined without the upgrade kit. With Blot, you can either remove the dragon head or fold Blot's beast head down further, while with Rippersnapper you can't do it without removing the dragon head (but please, don't use Rippersnapper as a leg, his peghole won't survive), meanwhile Cutthroat has the previously mentioned issue but again you don't HAVE to fix that.
I should also mention the instructions are pretty awful, being grayscaled photos, so you might want to keep a youtube video on hand instead.
