If you've got a relatively modern PC and have somehow missed out on a Prototype game, this is the perfect time to snatch them up. A mere $7.50 gets you both games in the series plus the Radnet DLC for the sequel that went for $10 on its own. The console versions of the original still go for $15-$20 and the sequel will set you back $35-$40, so this is a heck of a value. Prototype 2 is an awesome superhero game since it grants you more real-life superhero powers, only with an M rating so you can just slice and HULK SMASH folks into bits.
