In one cutscene, a soldier who gets eaten by a monster was replaced by a van.
The variety of hostages was reduced (e.g., no soldiers anymore) and they don't scream for help.
A few dialogues were changed.
The look of the first boss was changed and most graphical effects during the fight were removed.
In the second level, a sequence involving an electric chair was removed.
During the final boss fight, the whole second phase was removed - the reason is a Hitler reference.
