Unrelenting Force (Skyrim)

Unrelenting Force is a Dragon Shout in The Elder Scrolls V: Skyrim and is also the shout featured in the gameplay trailer.

Description
Unrelenting Force is usually the first shout the character will learn. After the Greybeards summon you to High Hrothgar, they will teach you balance and push effects. This is unique, as they will simply give you their knowledge and you do not need additional dragon souls to unlock them. This means you get the full power of the shout for only one dragon soul as opposed to the usual three required.

The first and second words of Unrelenting Force will stagger enemies caught in its wake for a short amount of time. When the third word is used, the target is thrown backward, inflicting additional environmental damage upon impact. Large creatures such as dragons will not be thrown, but will be staggered for a longer period of time. If a dragon breathes fire or frost at the player, and the player uses this shout, the attack will come to a halt.
