This page has videos for each of the four two-head fights, each using a different weapon, on medium security. Shotgun with regular ammo, shotgun with explosive ammo, and the handcannon.
Reminder to use the light attack to advance him to phase 2. If you use the heavy attack, you’ll just stay in phase 1.
SHOTGUN NOTE: One explosive shot = 4 shotgun shells, so using explosive ammo kills him faster and you get to dodge less, but you end up using more ammo in the process. So it’s a trade off. If you don’t have enough shells to use explosive ammo, you’ll have to dodge more, but you’ll use less ammo.
