Awesome things from the review
Your ingame mobile creates radio interference.
Thunder Storms.
The Stooges on the soundtrack.
In some missions you have to decide who lives and dies. ‘more time agonising over one particularly tough choice than we did over harvesting Bioshock’s little sisters’
Headshot drivers who fall on the horn and the accelerator.
In one screenshot, I count 21 cars at a set of traffic lights, and I can’t see behind.
Achievement for assasination missions called ‘Assassin’s Greed’

About the mobile:
‘You start out with Roman’s cast-off mobile, good only for text and calls, but a later upgrade is much more useful. You’re sent photos of assassination targets, can snap photos of your own to check on any police car computer, and can buy new ringtones and themes from your computer‘

Grumbles (pre-final build):
Cover system stumbling in box-filled environments
Slightly over-enthusiastic target lock-on
The occasional pop-up
