Pick out the bitz you would like to use and cut them from the sprue.

Start out by gluing the legs you've chosen to the base.

Once the legs are firmly attached glue a torso to the legs.

Glue the left and right arms to the torso at the same time to help you position them.

Attach the head you've chosen to the neck of the torso.

Glue a shoulder pad or two on to the top of the arms.

Lastly glue on any extra bit'z such as this bullet belt.
