Steam News announces a free week is underway for Cobalt, and the platformer can be played for free through midday Sunday. The pitch for this one asks as many questions as it answers:

Forget everything you’ve learned about combat. Cobalt’s slo-mo mechanic lets you perform moves that other games can’t comprehend. Play through the story and discover answers to mysterious questions including: What happened to the humans? Why am I riding a space hamster? How is my cyborg head so good at deflecting bullets? Multiplayer is a less cryptic, though equally enjoyable affair: face off against friends and enemies in local or online multiplayer, learn the intricacies of over 80 maps and 67 weapons, and dominate the leaderboards.
