Sponsored by the makers of the upcoming Will Smith version of "I Am Legend" - the I Am Legend: Survival sim is now up and running.
You can play either an uninfected human or canine, and fight off others who decide to play the infected "vampires" that inhabit New York City.
The build is good...the Orientation is good...the weapons and HUD are provided free of charge...and overall it's a great experience. The interconnected sims seem to lag a bit from time to time...especially for an underpowered, uninfected human armed with only a pistol.
Go check it out.
