The game's US version was completely uncensored, while the PAL-version of the game lacks a lot of gore/violence. Even though you can use a cheat to unlock the "Goremode", you still can't undo the censorship (missing splatter). The "Goremode" is also available in the US version; all it does is make the MDF-units and heavily damaged looters bleed. Still, you should probably buy the US version which (just as Wave Race 64) runs faster than the European version.
