After eight Invasions Mode seasons, the team over at Netherrealm has decided to start recycling content. As a result, most of the Season 9 Klues in Mortal Kombat 1 are the same as the ones found in Season 1, although there are one or two major differences that players should be aware of. The most obvious of these is that there are now only six Klues as opposed to the twelve that players were treated to when Invasions Mode first launched, but that's not all.
