The Muller-Powell Principle is a science-fiction adventure video game developed and published by Three Dots.

About

A science-fiction puzzle thriller taking place in the year 2032. You are Harry Herman, an employee of a science company Delta Laboratories that studies interdimensional traveling. You’ve been participating in a project that supposed to benefit all humanity, but something went wrong, and now you’re stuck far away from home. The words “The Muller-Powell Principle” is all you can remember. You must break The Muller-Powell Principle. You must, or all of this was in vain.

Gameplay

Solve various puzzles and trick enemies using physics interactions and your special tool – the Portable Energy Manipulator.

• Physics Puzzle and Interactive Environment
  • Many objects in the game can be picked up, brought somewhere or manipulated in other ways. Whether it’s a computer terminal, a box that you can carry, or a simple mug on a table. Explore various interactive environments to find clues and return to the riddle with a solution, which in some cases may be several.
• Portable Energy Manipulator
  • The device you carry throughout the game can absorb different energy types from the environment and use them to perform various tasks.
  • Absorb heat from fire and radiators to melt glass, blind security cameras with a beam of light, freeze physical objects in place by draining force fields scattered across Delta’s facilities, remove hazardous radiation from toxic puddles and use it to power generators, and even harvest quantum entanglement energy – the mysterious power capable of opening rifts between worlds. Utilize the device to it’s fullest potential.
  • Apart from solving environmental puzzles, your device can also be used against various creatures you’ll find in parallel dimensions. Most of the time you can’t defeat your enemies, instead you can use the Manipulator to outsmart them. Some enemies can be frozen in place using the force field energy, some are sensitive to light and can be distracted by shooting a beam of it in the distance. Some require more advanced strategies and combining various energy types to outsmart them.

Story

You wake up in one of Delta Labs’ off-world research facilities in an unknown dimension. The words “The Muller-Powell Principle” echo in your brain, you do not remember anything except this. Soon you find a radio, from which a friend from you past, Eugene, tries to connect you. Together with your companion you must travel across different dimensions and find your way back home.

Experience a non-linear story where your choice always matters. Will you uncover everything about the “Principle” and your past or simply try to escape? Which side will you take? And will you finally break the Principle? That depends entirely on you.

Setting

Make your way back to Earth through mysterious parallel dimensions littered with puzzles and secrets to discover, uncover mysterious connections between the worlds you visit and reveal the dark truth behind Delta Labs and your involvement with them.
