After completing ManBearPig, wait for a few minutes until Al Gore spams your mailbox. This mission will start automatically. Prepare for battle and talk to him inside his storage shed.
For the first turn, block the effects Al Gore's boring presentation, otherwise you'll get inflicted with sleep and screwed ailments. Also, don't waste any special moves or items.
Al Gore will call in reinforcements shortly after. You'll have to rely on status ailments, particularly Bleeding, Burning and Grossed Out. Don't use shock attacks against these enemies. The specialists' rifles are almost unblockable but they have low HP so you can get rid of them quickly. The secret service agent can use a stun grenade which is blockable and can deliver devastating combos as well.
Al Gore can use a skill to make himself regenerate and he also has a considerably high HP and armor rating so save him for last. You can use a Speed Potion to allow you to move twice.
This really helped 😀
