General Leadbottom

 is the boss of Tanks for Nothing, Part 2.

Attacks
A ranged boss, General Leadbottom attacks by spraying the target with his Thompson SMG. The target is, of course, you. He is also supported by a large troop of Commandos, who pose a larger challenge than him, actually.

Strategy
Standard procedure: Dodge incoming fire, hit back. Lather, rinse, repeat.

Note that after killing him, you will have access to a teleporter on the rear walkway. Use it to reach a secret room and gain experience.
