10 Video Games You Didn't Know Had Multiplayer

10. Grand Theft Auto: San Andreas

Despite Grand Theft Auto: San Andreas being one of the most beloved video games of all time, few who played it were aware that the console versions actually included a hidden two-player mode.

Players need to keep an eye out for strange icons scattered around the map: finding a pair of skulls will allow you to play a co-op rampage mission, while discovering a pair of red figurines will let you play co-op free roam.

In rampages, player two will always appear as a hooker, but in free roam, they can pick from a number of different skins.

On paper it's a fantastic idea, and though it's certainly fun, players also have to cope with the fact that they're forced to share a camera on a single screen, and so can't stray too far from one another.

The fact this mode was basically a multiplayer prototype is likely why Rockstar didn't make much effort to actively advertise it, but it's still a neat addition to an already ludicrously content-rich game.
