|“||Using Nintendo's controller to navigate first-person shooters is going to be an amazingly empowering, freeing experience. We know this because Nintendo demoed a modified version of Metroid Prime 2 Echoes using the new peripheral, and the potential is undeniably jaw-dropping. In the demo, players could move Samus through the environments with the attached analog trigger. The need to lock-on to enemies, however, was been eliminated, thanks to a new level of precision aiming made possible with the pointer. In a level of accuracy rivaled only by a PC mouse configuration, gamers could simply use the device to point and shoot."||„|
The Metroid Prototype was an early prototype of a Wii version of Metroid Prime 2: Echoes. When Nintendo first demoed the "Revolution" remote (later Wii Remote) at the Tokyo Game Show on September 15, 2005, and in America at a New York hotel on December 8, they allowed select press to try eight tech-demos in private. Most demonstrated simple concepts to introduce the capabilities of the new device. In order of showing, the demos were: a block shooting-range, the fishing game that ended up in Wii Play, an electric maze with a baton, air hockey, shooting baskets, a game where a Pokémon had to be found hidden among others, and flying a paper plane in Super Mario Sunshine's Delfino Island.   
The final and most advanced demo was a version of Echoes that had been retooled by Retro Studios to incorporate pointer controls. This demo was the only one to use (and thus introduced) the Nunchuk. The buttons were mapped to: A:Jump, B:Fire, Z1:Switch Visors, Z2:Lock-on/Scan, and Select:Morph Ball. The last three buttons were eventually renamed "C", "Z", and "-", respectively. This was the earliest version of the Wii control scheme that would be used in Metroid Prime 3: Corruption two years later, as well as the New Play Control! and Metroid Prime Trilogy ports of Echoes and Metroid Prime, with some changes. The fire and jump buttons were switched (although they can be swapped in the Options), the - button selects visors and the C button enables Morph Ball. The Z button still allows for Lock-on and scanning.
The demo was put together by the late Mark Haigh-Hutchinson and Andy O'Neil. According to IGN, a Revolution prototype arrived at Retro Studios two months prior to Tokyo Game Show and Haigh-Hutchinson immediately set to work. He had to keep it a secret from the other employees at Retro. It took him two months to complete the demo, but Haigh-Hutchinson enjoyed it and his work left Retro Studios "ecstatic". They saw in it the potential of the Wii controller for Corruption.
