Layers of Fear is Free on Steam. A BUNCH of you already have this, not sure why.
I forgot I had it. I think humble bundle gave it away free a while back. I went to claim the steam link only to find it was already in my library.
FREE! Guns of Icarus - Alliance
Female protagonist sale on Humble!
If you're into Telltale-like games both Life is Strange and Dreamfall Chapters are great (the latter especially if you were into The Longest Journey and/or Dreamfall).
Other highlights: Dishonoured 2, Tomb Raider (and lots of DLC for it), and the PC port of Okami.
Also recommending Bayonetta, Beyond Good and Evil, and Alien:Isolation in that bundle.
This is free til Monday. Mixed reviews but looks like maybe stupid fun for 1-8 people if anyone wants to try it together!
I installed it. I'd be up for trying it with some IC Peeps.
_k and I tried it last night but weren't able to even get in to a game together.
Looks like we need to get enough people together to start our own server game.
All the Borderlands 2 for $6 until June 17.
Along with the announcement of KSP2 today, KSP is $10 until Sept 2.
Poly Bridge is $2 for another 18 hours. Great game.
