This is an inclinometer USNC Mammoth Halo Mega Bloks Set that comes with nearly all pieces and parts, and is partially put together. The last step I was on in completing the build was step number 72 on page 35 from the halo mega blocks booklet website downloaded page online which is free to use and can be accessed from a mobile device. Also included is the halo mini figures some with missing parts. Also there are only 4 big wheels. Thank you for looking and happy bidding.
