Dear ShaDoW,
We use inhouse engine which utilises 2d backgrounds and 3d characters for cutscenes. I'm responsible for all Voice Acting, Steve did all character models and mocap editing and Tim painted/rendered all 2d backgrounds (which were inspired by other games such us Oblivion and RTCW). We've put 10 years of hard work to make this thing happen! I'm glad You all like it.
Best Regards,
Laurence Francis
