Assembly (Using the images for reference)

Chest
Press the gray pieces into the corresponding places in the chest, use glue to secure them if necessary.

Armor
Press the Lambda Symbol into the Armor front. Glue Armor Front to Armor left and Armor right, then glue the two part of Armor Back to the back. Small Clamps are very helpful for holding everything in place as the glue sets.
