During the first day on Unreal Engine, I created my basic castle, landscape, moat, inner keep doors and drawbridge. I then textured these to add detail and allow me to differentiate between the standard grey boxes. I also learnt how to animate the doors and drawbridge to allow them to open when the player enters a specific area.
The player will begin the game outside of the castle walls. They must kill the enemies firing down from the walls before they can proceed. The drawbridge will then drop when approached and the player may continue.
