Agent 47 is back, and Hitman is a puzzle game once again. I’ll never quite forget the first time I saw 2012’s Hitman Absolution in action. A few things made that E3 demo particularly memorable. For one, the air conditioning in the box of a presentation room was broken, leaving the 30-minute demo sweltering and uncomfortable. The volume was cranked up hugely perhaps to distract from this fact, and inception-style ‘bwahhh’ horns in the demo practically blew my eardrums. Afterwards IO Interactive staff handed over super-cool business cards etched into metal with edges so sharp it might actually pass as a concealed weapon.
