Imagine yourself as a bodyguard working for a huge research lab. One day, the whole lab starts exploding and projecting some weird matter around.

You start panicking, but before you start doing anything, a researcher arrives towards you to give you a weird looking dagger. You don't really understand, but he only tells you one thing : "You look physically fit, you could do the job, just take it outside of the city, as far as possible. Don't ask any question, we don't have time, just run. Oh and don't hesitate to use it, it could serve you right. Now pray for me."

Your mind is completely blown, but you don't hesitate, you respect the order, and you start running.

There you go, you are thrown in a nervous 3D parkour game, with an original mechanic brought by this famous dagger...
