Chrysalis

The Chrysalis is the final boss of Resistance: Retribution.

The Chrysalis is actually Raine Bouchard, whom of which had completely transformed into a Hag, but the end result was actually an entirely different being. Due to the experiments that her father took upon her, the mutation ended up horribly. The Chrysalis is now invulnerable to normal bullets, is able to maintain Raine's mind, and is remarkably similar to Daedalus.

After a long, furious fight between James Grayson and The Chrysalis, Raine manages to take control enough to say how Carriers everywhere are dying, but now Spinners are taking there place. She mentions how the Chimera are too advanced and will keep evolving just before she becomes completely infected. James pulls out a pistol, apologizes to Raine, and shoots her in the head, feeling the same as when he ad to shoot his brother.

Combat
The only way to puncture through The Chrysalis' shield is to activate one of the towers found throughout the stage. Only one will be active at a time, so the player must be careful, as The Chrysalis' attacks are not the only threat. 5-8 Hunter Drones will also appear.

Once a tower has activated, it will fire a laser that breaks its shield. The player is now free to fire away. After a certain amount of time, it will retreat to a location from which it cannot be fought. More drones will appear. Only after they are defeated will The Chrysalis re-appear. Repeat the process. When half of its health is drained, two armored Titans will appear instead of drones. The same rules apply, so defeat them for the boss to return. Repeat this process until The Chrysalis is finally defeated.
