The document outlines a tower defense game prototype created by DIG - Dreamers Interest Group using the Unity3D game engine. The group includes 8 members who aimed to learn Unity3D and create a basic tower defense game. The game allows the user to build towers along a path from a dock to a town hall to defend against an orc army. Money is earned by killing orcs and over time, which is used to build towers to protect the village and prevent its health from depleting. Future goals include expanding tower placement, adding multiplayer mode, and including more villages to defend.
