Another thing that was changed for the title screen is that the North American and Japanese versions had blood dripping effects from the title to the blood pool, but in the European version, the title screen just faded in through pixailated text and had no blue water dripping effect. The zombies were changed from pink to green to make them less gruesome. In the European version, Eric's spear does not impale him after he dies. There was a rearrangement of enemy placement as well, making the difficulty either easier or harder depending on where in the game the player is. Also, only some sub-bosses use the life bar meter to show damage, whereas others don't.
Despite Australia being part of the PAL region, Sega Australia, the distributor of Konami's products on the Mega Drive used an uncensored version of The New Generation, with almost everything intact to be as close as possible to the Japanese version.
