Steam now offers Resonance, a new adventure from indie developer XII Games, offering a 10% discount during its first week of availability (thanks nin). Here's a description of the game:

When a brilliant particle physicist dies unexpectedly, the race is on to secure his terrible new technology before it falls into the wrong hands. The lives of four playable characters become entangled as they fight against the clock to find the dead scientist’s secret vault.

The suspicions they harbor, the memories they guard, the connections they share - all will converge as these four ordinary people work together to prevent a potentially cataclysmic disaster.
