Double Exp, also known as Double XP, was a process back in the day where Zorg rewarded the whole game with double experience from all fights for one whole weekend if, in the previous month, Legacy had been voted into the top 10 in the top game sites.

However, after observing that people were taking advantage of it (by saving up all their credits and spending it all on Hunting during Double EXP), Zorg permanently removed Double EXP from the game.

Zorg gave Double Exp as a gift to the whole game on Legacy's 2nd and 3rd birthdays. Scott awarded double EXP for Legacy's 7th birthday.
