The Muller-Powell Principle

The Muller-Powell Principle is a sci-fi thriller set in the near future. You play as Harry Herman, a scientist at Delta Laboratories, a company researching interdimensional travel. After a project meant to benefit humanity goes wrong, you must explore surreal worlds, solve puzzles and uncover Delta Labs’ secrets as you try to set things right.

Parallel worlds

You are alone in an off-world Delta Labs research facility in an unknown dimension, where everything seems close to falling apart. Your route back to Earth leads through parallel dimensions filled with puzzles and secrets. As you explore, you uncover connections between the worlds, the dark truth behind Delta Labs and your own connection to the company.

A radio transmitter lets you hear from Eugene and Alex, old acquaintances who appear to offer help. One is friendly; the other believes you made a serious mistake and blames you. Your choices determine whose advice you follow, whom you trust and which side you take. The story has multiple endings, reached through different choices.

Puzzles and environments

You solve physics-based puzzles by exploring and interacting with the environment. Some solutions involve finding a generator and connecting it to power a room; others require a more involved approach. You can use computer terminals to find clues, remove obstacles and carry objects such as boxes. Even a mug may prove useful, and puzzles can have several possible solutions.

The Portable Energy Manipulator

Your Portable Energy Manipulator absorbs energy from sources in the environment and uses its properties to perform different tasks. Heat from fires and radiators can melt glass, light can disable security cameras, and energy from hazardous radiation in toxic puddles can be absorbed. Later, you encounter quantum entanglement energy, which can open rifts between worlds.

The Manipulator also helps you evade the strange, dangerous creatures in parallel universes, which you usually cannot defeat. Force field energy can freeze some enemies in place, while others are sensitive to light and can be blinded. As you progress, finding a way out of traps requires more thought.

Story and lore

Notes, environmental storytelling and conversations reveal the stories of the locations and characters you encounter. Your decisions shape how you pursue the truth: you can try to get to the bottom of what happened or focus on escaping.
