Al Gore is one of the many Side Quests in South Park: The Stick of Truth. After completing the ManBearPig by placing the three ManBearPig sensors around town and the "defilibrator" in the sewers, you can find him in his storage unit at U-Stor-it-Facility.
It turns out that Al Gore is very annoying as he keep spamming and flood your Facebook account after you complete the ManBearPig side quest for him.
Make your way to his hideout and confront him about this issue. He will initiate a boss battle against Mr. Gore.
Note that Al Gore is a tough fight, because he constantly heals himself. His attacks are fairly standard.
He comes out strong with his Global Warming presentation attack. Spam A (to counter like you would in a regular attack in order to counter Al Gore’s presentation and keep yourself from falling asleep) or prepare to fall asleep.
Then he will summon 3 secret service agents, armed with guns and billyclubs to protect him. At this point he is immune to Stun , you need to take out these guys straight away.
Once you have taken out all secret service agents now you can start fighting him again. Keep attacking him and block any of his attach.
Also you will need to unfriend him on Facebook to stop him from spamming your account.
Once defeated loot his body and grab the key to his secret room. Head left in his hideout you will find a door. Use the key to unlock the door and loot the place including a ManBearPig specific weapon that is very helpful in a later boss fight.
