A base is a very important part of Doomed 2. A good base can help you get to the top and there are some places and items you want for your base. The buildings that are mainly used are walls/spiked walls, doors and turrets. A good place to put your base is in the corner or next to/surrounded by lava. A basic setup is to make a square/rectangle of spiked walls with a door in the middle of 1 or more sides and then put torches in the middle/corners with turrets on the sides. You could take this a step forward and have spiked then regular walls making it twice as hard to break in.
