Mortal Kombat 1 in my opinion has been off to a rocky start. The game had problems at launch and still has some lingering issues. NetherRealm have released a few patches to fix things but it's still got a long ways to go. However, to their credit, one of the things I was thrilled to see updated with some much needed quality of life fixes was Invasions mode and they came just in time for Season 2 to begin.
Season 2 of Invasions titled "Season of Blood" is underway and this seasons Invasion boss will be Nitara. Updates to invasions includes and a new Mesa or new map in called "Rampart." Other updates will include new bosses, new map layouts, a new seasonal progression tower and all new skins and gear for various characters in the game which can be earned via the seasonal store and can be bought with seasonal credits.
The Season of Blood is underway now and will run until December 11th.
