The seasonal kontent that’s on offer in Mortal Kombat 1 can be incredibly repetitive, with each season requiring players to battle their way through six of the same seven or eight Mesas and then take down a final boss. Thankfully, Invasions Mode Klues do at least provide something a little different, requiring players to use both their brains and a wide variety of kombatants and kameo fighters in order to get the job done.
