Build and Defend (or B&D) can be best described a Survival Strategic Multi-player Rogue-like Sandbox game. The game is mainly played at the 3th person (like Zelda 3). The main goal of the game is to build and organize a fortress in order to survive waves of monsters. To do so, and among other things, you will have to build ramparts, train soldiers, organize food production, resources gathering and crafting of tools. For the larger monsters, you will have to get an equipment and fight yourself. If you are brave enough, and to get the rarest resources, you will also have to explore dungeons, caves, and tombs. B&D can be played alone, cooperatively with several players on the same computer, or though internet. Several experimental mods are available, including a first person PvP, a creative mod, and the castle mod.
This small tutorial shows the basics of the game.
