These two are pretty much identical aside from the chests and vehicle parts. The arms, legs and internal torso parts are shared. I like the detail of the miner’s lights on the usual g1 design. Articulation is decent but the double jointed elbows and knees are really nice. Bonecrusher’s knee shovels restrict articulation a lot though. Eyes light up with a magnetic LED system. The guns are mostly identical but have different peg and port placements for combined mode. They both have magnets built in to activate the eyes.
Transformations for the two is alright. Relatively simple and logical though some clearance issues arise if certain steps aren’t done in. A specific order. Not bad at all.
Vehicle modes are adequate but oddly flattened and long for the type of vehicle they’re supposed to be. No wheels for rolling but have decent undercarriage storage for guns. These two don't really have a lot of vehicle playability. Bonecrusher is a brick and scavenger’s shovel has decent articulation. Nothing to write home about.
