The utility hut will be able to create, Spears at lvl 1, Cross bows at lvl 2, Parachutes at lvl 3, and birds at lvl 4. When creating these items you add them to the troop making it stronger but more housing space. Spear would be deployed on a barbarian make it do more damage but 2 housing space. Same with cross bow and archer. Parachutes would allow certain troops to glide over walls until landing or being shot down. Birds will have archers as riders so that the archer is now and air unit.
Couldn't find any pictures but wouldn't that be cool.
