Start out by gluing the Chaos Terminator legs to the base.

Match up two torso halves, spread some glue along the edges, and press them together.

Attach the torso to the Terminator legs with a small amount of glue.

Glue some spikes to the back of the Terminator torso. Dry fit them first to make sure they fit.

Attach the ammo canister to the Autocannon. Make sure it fits before you glue it.

Glue the arms onto the torso while paying attention to how you pose them.

Lastly, attach the head and the shoulder pads to the Terminator.

Now you're done and have an assembled Chaos Terminator. Rinse and repeat!
