This Seeking Tech tutorial will show you how to acquire The Pain Hornets’ Nest in Metal Gear Solid Delta: Snake Eater.
Before fighting The Pain, make sure you have a regular Hornets’ Nest in your inventory. The last opportunity to get one before facing off against The Pain is during the Ocelot boss fight.
Once you get the regular Hornets’ Nest, throw it on the same platform where The Pain is standing. Make sure it doesn’t fall off into the water. If it does, restart the fight.
When the nest successfully lands on the same platform as the boss, finish the fight. Afterwards, make your way to the aforementioned platform to acquire The Pain Hornets’ Nest.
