Resident Evil: The Mercenaries 3D - on sale this week - won't let players delete any saved data. The 3DS survival shooter doesn't offer secondary save slots either, meaning there's not a chance for other players to start their own games.

Japan first experienced the issue when the game launched earlier in the month and it's present in both the NTSC and PAL editions of the game. This may have been done to reduce the value of trading the game in at retailers. The Mercenaries 3D launches on Tuesday in the US and Friday in Europe.
