Last time Gamespot had a chance to take control of Alex Mercer and run him through an infected present-day New York City, they got a feel for his unique killing abilities. This time around, they were given the option of taking things a little slower and trying out the pseudostealth mechanics available in Prototype.
Warped forward to about halfway through the game, their initial job was to seek out and make contact with Dr. Ragland, an as-yet-unintroduced medical contact, at his lab. With the point marked on our map with a glowing yellow marker, they decided to stay above the fray going on at street level by dashing up buildings and then hurling ourselves off of and gliding to the next structure. Once they got close to their target destination, they descended to mingle with the crowd of citizens while wearing our now well-recognised hooded sweatshirt. Given that their progression with the game hasn't been chronological, it's still unclear what sort of awareness the locals have of Alex's presence or whether they perceive him as a threat.
