UPDATEIt has now been confirmed by user Tyaren here on Resetera who has the game updated with the day 1 patch, that The Krypt and Towers of Time are indeed unavailable when you are offline. So the tweet by the developer was true and the day 1 patch did not fix this like some had speculated.So according to the Mortal Kombat Reddit , a dev from Neterrealm posted a tweet confirming that the game will require a online connection to earn gear and play the Towers of Time mode and access the Krypt. He has since deleted the tweet for unknown reasons (maybe fear of negative backlash?)As someone who don't play online only games I find this extremely disappointing. The gear unlocks and Towers of Time/Krypt are the main parts of the game that gives it's incredible longevity.Injustice 2 let you do 95% of what the game offered while offline, including the Towers of Time like mode, Multiverse.And the gear doesn't offer any gameplay advantages either, it's purely cosmetic, unlike in Injustice 2 where it actually did affect gameplay.I wish Neterrealm would have been more upfront about this from the beginning as I would not have pre-ordered the game had I known.Gonna be tough for the Switch version when you're out using it in handheld mode without a internet connection.
