Extended ending:
—————-
Successfully complete the game and wait for the credits to end. An extended
sequence featuring the game’s true ending will begin.
Fall through floor:
——————-
Play the rooftop level just before the intermission of Max blowing up the
satellite tower under the normal difficulty setting. At the start of the
level, run and collect the items in the wall. Do not sneak up on the first
man; he must turn and see you. Walk behind him when he stops. Wait until he
turns around, then press Y to flip him. This will cause you to fall underneath
the floor and bypass all the guards. Run to the end of the level where the final
locked gate is located. Run into it to complete the level without running out of
time or being seen by the guards.
