Balazs Oszvald has used Blender to model assets for the indy game 'The Incredible Adventures of Van Helsing'.
I just want to inform you, that The incredible adventures of Van Helsing has just been released on Steam.
This is an indie RPG game placed in a gothic-noir world of Borgovia, where the son of the famous Van Helsing is going to save the day.
...and what does it have to do with Blender? Of course it has a lot of Blender-made stuff in it.
I have worked as 3D environment artist and used Blender all last year creating a bunch of assets for the game. For technical enthusiasts: Blender was used for modeling and UV editing, Photoshop and proprietary software for texturing. We used the FBX format as a common medium to communicate between Blender, XSI and the in-house software. Most models use 2 UV sets for extra high texture detail. Nearly everything has diffuse, specular and normal maps on it with nice material shaders.
