Are you a CoD fan and a PS4 owner? Well then this Friday, August 23rd, you'll be able to participate in the Call of Duty: Modern Warfare open alpha test, which is exclusive to PS4. You don't need to pre-order the game or even have a PlayStation Plus membership. The catch is it's only this weekend, so you'll have to jump on this opportunity while it lasts. You can check out the trailer below.
