SOCOM 4's private beta began yesterday and Zipper Interactive has outlined what people will have to look forward to over the next seven days.
The beta, which is only available to a select few PlayStation Plus members, will go through almost all of the game's features. Every day, there will be something new to check out.
If you want to find out more about all the game's different modes, which include Suppression, Last Defense, Uplink and Bomb Squad, they're all outlined at the PlayStation Blog.
