Well that's forty-five down...

Finished off Enslaved today, and the ending puts an interesting level of depth to the story.

In the last levels Trip, Monkey, and Pigsy steal a giant mech monster and use it to storm the slaver's pyramid base. After a huge boss fight Pigsy sacrifices himself by blowing up the mech to destroy the remaining defense, and that touching moment is ruined with the "smokey bacon" achievement popping up...

Then it's revealed that what the "slaver" is doing to all the people is plugging them into a mass Matrix like simulation of the early 21st century New York (which Monkey sees glimpses of in the masks he picks up). This way he is giving the people a escape from the hostile dangerous wasteland of the real world, but by force. Monkey is even drawn into this simulation but then Trip kills the controller and ends the simulation for all the slaves. So in the end thousands of people are freed from a content illusion and now have to face a harsh reality, and the game dosen't say if this was good or not or even what happens next.

I may go back at some point and pick up the rest of the achievements, but for now it's on to Allan Wake.
