As soon as the scene starts, go backwards (which is left). Knock down the boards with your axe then crawl under the opening. Run to the body and examine it for a health upgrade.

This can be done in a few places, but the one that makes most sense is on Act 2 Scene 8 (Lydia). You will obtain a fire axe on this scene. Once you do, break the lock and kill the first enemy you see. Continue past the other ignoring it. Break the other door down and get the enemy over near the railing. Get on the left side of it and push it until it falls over the railing. 

After getting the axe in Act 1 Scene 4 (Outskirts) you will be able to obtain this. As you are fighting enemies during the game, you will likely get this by chance. Hitting an enemy during a swing (pressing ) that makes contact with it's head will result in a decapitation. This will gain you the achievement. Usually this is best done with groups of enemies and swinging randomly at them.

Knock an enemy over by pressing  to swing your axe. Now get near it and hold  and you will swing your axe down and kill it.

The first chance you will have is in Act 1 Scene 4 (Outskirts). After obtaining the axe, you will fight off enemies in this level at times. Press  twice in a row and you should perform a combo. Your character will swing the axe and then push the enemy with the handle.

This is one of those achievements where you would have obtained it without needing any help. When enemies start grabbing you, the game shows to press  repeatedly to escape. Do this once for the achievement. It can be obtained in the very first level with the enemies.

This achievement means to avoid damage, not death. That means if you are too high up, you will not fall into a roll and will die. The first spot to obtain this is listed below. As you are falling, you must hold  to roll once you hit the ground. It is very easy, you just need to find a spot to do it.

This can be obtained in the first level. There will be a point when you find yourself outside and have to climb up ladders. Once at the top, you will have to make your way down the other side. There is a ladder that leads down. Instead of going down the ladder, press  on the railing to hang on it. Press  to let yourself drop. Hold the to roll and gain the achievement.

You will later be taught how to do this, and likely get the achievement there if you had not gotten it yet.
