Murder Your Maker video emerges.
Prototype 2 looks like a dead cert for a Spike Video Game Awards reveal after flashes of footage of the original game popped up on viral website Murderyourmaker.com.
It is the latest in a series of teasers for the openworld superhero sequel that began with the launch of the Murderyourmaker website last month.
The plot thickened when the third of three zombie-related VGA images found its way onto the internet.
