Metronome's distinguishing feature so far -- apart from an admirable art style -- is its focus on sound. The developers intend to let players record any sound they hear. The sounds can then be played back to use as weapons, to affect other characters, or to change and manipulate objects in the world.
Team Tarsier is building Metronome with Artificial Studio's Reality Engine. Take a look at a first batch of screens to see how the game is shaping up.
We expect to hear (ha!) more on Metronome from the show floor next month. Stay tuned (ha!).
[Update: While Team Tarsier has yet to acquire a publisher for Metronome, we have been able to confirm with spokespeople from the company that their little experiment in interactive sound is intended for next-generation consoles.]
