In one of the ancient castles, a portal appeared from which demons began to come to our world. In the game Demons Down you will have to enter the castle and destroy the portal. Before you on the screen you will see your character, who will be in one of the zils of the castle. Using the control keys, you can tell your hero in which direction he will have to move. Look around carefully. As soon as you notice a demon, engage in battle with him. Using firearms and shooting accurately from them, you will destroy your opponents and get points for it. Explore everything around you. In some places there may be caches in which you can find ammunition and first aid kits.
