Indy punches Mac in the nose just as he promised.
The opening scene of the movie involves a group of Russians dressed like Americans killing a group of American soldiers all of it is offscreen, but the next scene shows their dead bodies.
A group of Russian Soldiers kill Ancient Temple Guards (offscreen, but the bodies are shown)
Lots of punching and kicking literally....some characters are shown bloody after a fight (but survive just fine).
Several scenes with knife and gun-play (but without almost any blood as a result of gun shots).
Some ancient dead bodies are shown, one man was well preserved and when the wrapping comes off he disintegrates onscreen.
Lots of jokes about dead bodies. In one scene Indy says "hold this" and throws a mummified corpse at his friend; a close up of the dead face is shown. This scene can be shocking in a 'jumpy' kind of way.
Indy kills a man by forcing a blow dart back into his mouth. This is sudden, and rather disturbing.
Mac is shot in the foot.
