Sorry for this question but I just bought God of War and I'm stucking in the beginning. I killed all the enemies on the ship and now I can't open the door on the bottom. It says I should press R2 and thats what I do, but there isn't anything happening.
Please help me!!!

Tap R2 repeatedly quickly until it opens. If the "R2" simbol is moving up and down then this is what you do every time
