Hm, no demo version of this? It's too expensive to buy yet, but I guess many people would try the demo if there was one.
Deadfall runs nice on my i7-2700K with 8 GB ram and a Geforce GTX660Ti. This game obviously uses the Unreal 3 engine and shares the same bugs with Painkiller Hell & Damnation for example. Like long loading times and effy mouse control (fixed by disabling mouse smoothing in game options)
Sadly the link is even more confusing. Games that show me a linux icon like Garry´s Mod are listed by steamDB as showing NO linux icon. So something is definitely wrong there. In addition: There are games like Braid that have really no linux-icon, so steam won´t let me install it - but steamDB says it should work, and through the humble-bundle installer it definitely works on linux.....
So how did you make deadfall adventures install via steam on linux???? Is there a hack?
