Big Bertha

Big Bertha is the first boss from Metal Slug: 2nd Mission. It is fought at the end of Mission 1 (The Front Line).

Boss Strategy

Big Bertha is a stationary cannon that constantly shoots on the same spot. The explosion produces residue, and it is able to hurt the heroes. Various Rebel soldiers show up to defend the cannon. Big Bertha is destroyed by firing at the train's cabin on the right.

Trivia

Big Bertha appears on the background at the Shoe & Karn fight in Metal Slug: Super Vehicle-001.
