GamaSutra - Hitman Absolution director Tore Blystad faces a lot of challenges with the latest game in the franchise. The team has built an entirely new engine, Glacier, to power it.

When your game is about sneaking through a realistic world, the things that aren't realistic stand out just that much more. And as all game designers know, there's another source of tension there -- because what's realistic is not necessarily fun.
