How to unlock the Fallen Sentinel achievement in X-Men Origins: Wolverine - Definitive Guide
The first stage it will try to stomp Wolverine or grab him and laser him. There are metal panels on the ground with eclectic current in them. Get the sentinel to stomp or punch them to stun him. Then attack his hands or feet (blue in feral vision) to damage him. Eventually his hands will explode and then with more damage so will his feet.
Once that is done, it will take off, with Wolverine hitching a ride. You will regain control when wolverine is in free fall towards the sentinel. Use feral vision to easily see the red debris. Dodge the debris and Wolverine will automatically take out the engine when he lands. Fall off and repeat for the 2nd engine. When you land for the 3rd time mash the B button to rip open it's chest and kill it.
Side note: Keep an eye out after you destroy the first engine for an O ring, fly through it for an achievement.

This is earned near the end of Chapter 3, Level 10 - Sentinel Mark I.
A protracted battle, first with Wolverine squaring off against the Sentinel on a roof. Here you will need to damage his feet and hands, by using the destructible shock pads on scattered around. Once you have sufficiently damaged him, an aerial section will ensue, which is basically a QTE. Once finally brought crashing down to earth, the trophy will unlock.
If you are struggling with this Boss Fight, please refer to WickedNite's Supplemental Enemy/Boss Strategy Guide for tips.
Note that Threading the Needle can be earned during the aerial section of this battle.
