Lol, you're telling me to go on YouTube to look for execution animations? Play the game, will you. You can only step on certain kinds of draugr's heads and you can only rip apart certain kinds too. Each enemy only has ONE animation.
How many ways to execute an ogre? A dark elf? A wulver? Just because two kinds of draugr have two animations doesn't mean everyone has them! Play the game before you comment! There's multiple per enemy? Is this a joke? Pfft.
The axe R2 move is an ATTACK. it's not an execution.
Funny you should say that, if you look on my wall you'll see on May 2nd I posted "Just finished God of War... it was beautiful."
