[Whoops. It appears City Interactive ran into trouble with the ESRB over the contents of this particular video; we’ve been asked to remove it. Soz.]
It may not be clear from this short video, but the Warsaw-based City Interactive (whose debut title this is) says Sniper: Ghost Warrior all about ‘true realism’; breathing, distance of a shot, fall-off of the bullet’s trajectory, and environmental factors such as wind direction are all factors to be taken into account for the trigger squeeze to result in that satisfying “boom, headshot“.
The game’s out in June.
