Featuring procedurally generated levels, the goal of each map is to collect gold and reach the exit with your team of up to four characters. The trick is that all of your units perform the same single action (move up, use a special ability) each turn. This intriguing game mechanic produces a lot of strategic planning and puzzle solving to keep your team alive. Each class has a different special attribute to offer, and items to recover health, abilities, or earn bonuses can be collected. The Nightmare Cooperative offers a challenging, thought-provoking puzzle game with roguelike elements.
