"NIGHTMARE BREAK" is a single-player 3D action adventure game that pursues the "fun of swordplay action." Although it consists of only one bleak stage, there are enemies to defeat and fragmented stories to discover. You control a knight wielding a great sword and aim to escape from the nightmare world by clearing the stage. There are no growth elements such as equipment or builds, but you can become stronger by picking up items scattered along the way. Although strong enemies await, there are also checkpoints, so you can enjoy the game with peace of mind. The Nightmare Lore No one knows the lore. The Challenger got two choices. Kill the Nightmare Lord and will be the Lord myself. Or must break this nightmare.
