There's always a fallback plan. And it usually involves ramming something.

Thief can't pick the lock on the dungeon door? The fighters ram it with their bodies.

Security in the military complex you need to infiltrate to uncover evidence of a government cover-up of alien visitors is too tight? Ram the place with heavy construction equipment. (Preferably dropped from a zeppelin.)

Smarmy bad guy successfully sets himself up as the innocent victim while painting you as a crazed conspiracy theorist, resulting in the police dragging you away as you try to bust his lavish cocktail party to accuse him of being The Green Demon and plotting to destroy the city? Ram his face with your fist!
