*UPDATE 9/6/13 1:33 PM* Angel should be available at $0.00 at midnight PST Sepbember 7. It will remain free Sept 7-9.
I am very sorry to announce that there are technical difficulties preventing Angel (Impossible #1.5) from being priced at $0.00 in time for the publicized period (September 6-8). I am currently doing everything in my power to rectify this. As soon as the price drops, it will remain free for a 3 day period. I will post an update here and on facebook when this is resolved.
