Don't know much about this weeks games.

For $1+:
Splice + OST
Fractal + OST
Pulse + OST

For $6+:
Intake + OST
Auditorium + OST

I have Auditorium on the PSN and I can't say it's an amazing game. It's fun, but a tad too fiddly. A quick check tells me that I have Fractal on Steam from a previous bundle. Mixed with the fact that two of this weeks games don't activate on Steam, I think I'm sitting this one out.
