Oddworld: Stranger's Wrath HD

Story-related. Cannot be missed.
Packrat is protected by a shield powered by four generators, all of which have conveniently placed Zappfly switches. Hide behind one of the mesh fences near Packrat’s platform to avoid being hit by his missiles and shoot out three of the generators. Save your game!

Shoot a few Fuzzles on the ground at the base of the platform and then shoot the fourth generator. The shield will be down, so quickly fire a Boombat behind Packrat to try and knock him off the platform. As soon as he falls to the ground, he will head for one of the doors to head back up. As soon as you see Packrat falling to the ground, run towards him. The Fuzzles that you fired earlier will attack him, preventing him from heading to one of the doors. Immediately fire your charged Zappflies and Thudslugs until Packrat is knocked out and then bounty him as normal.

If you fail to stop Packrat from going through one of the doors and back on the platform, re-load the save you made before you started firing Fuzzles. Once Packrat heads back to the platform, he will reactivate the shield generator and Outlaws and flame turrets will join the fight. This makes bountying Packrat much harder.
