Let's face it, not every game was made for co-op play. Sometimes the nature of a game just doesn't work well with two or more people at the controls at the same time.

The sweltering summer months make us want to stay indoors and get our game on. Thankfully there's a few titles out there that help break that heat. This month we look at five single player titles including Singularity, Prince of Persia: Forgotten Sands, DarkStar one, Persona 3 Portable and more.
