Dr Chaos (USA)

In Dr Chaos, players control Michael Chaos, a brave scientist, as he explores the vast and mysterious mansion of his brother, Dr. Guild Chaos. This mansion has been transformed by an alien entity named Chaos, who is attempting to invade Earth. The game combines two primary perspectives: a top-down map view and a side-scrolling action view.

When in the map view, players can navigate between different rooms in the mansion, each representing a distinct area. This is where you plan your movements and search for "warp" points to enter action zones.

When Michael passes through a warp point, the game switches to a side-scrolling perspective. Here, players will encounter numerous mutated monsters, dangerous traps, and other obstacles. Michael is initially equipped with a knife, but can find and utilize various other weapons such as guns, grenades, and even an energy sword. Effective weapon use is key to survival.

Beyond combat, Dr Chaos also requires players to solve puzzles to progress. This often involves finding crucial items like keys, cards, or special devices to unlock new areas or activate mechanisms. Many secrets are hidden within the mansion, encouraging players to thoroughly explore every nook and cranny.

The ultimate goal is to locate and defeat the Chaos entity, thwarting its invasion plans. The game has light survival elements, as Michael has a health bar and needs to find healing items. With its eerie atmosphere, unique gameplay, and challenging nature, Dr Chaos delivers a memorable action-adventure experience on the NES.
