The Too Human demo has been doing the rounds on many Xbox 360 consoles, but many gamers were saddened to know that it had only one of five player classes from the full game.

Apparently, it does include the other four classes which are unlocked through a time release code. In fact, the second class – Berserker – became unlocked last Friday, and Commando, the third class, is expected to be unlocked August 12.

However, there is a way to unlock all classes in the game. This includes changing your console’s internal clock, and doing some controller mumbo jumbo. Be sure to check out this post for the nitty gritty details.
