The huge new Mortal Kombat 1 Khaos Reigns update is out now on PS5, Xbox Series X|S, PC and Nintendo Switch. Weighing in at a whopping 72GB on PS5, version 1.007.001 introduces a wealth of new features to the game, from new characters and story content, to various balance fixes, costumes and even finishing moves in the form of Animalities. As you can see from the patch notes below, the reason this particular update is so large is because NetherRealm has implemented a new file compression feature to reduce game size for future patch releases. Unfortunately, however, this isn't much help now, because this particular update is absolutely huge, and takes the overall install space for MK1 to beyond 200GB. On the plus side, it's great to see Animalities make a return, alongside even more new Brutalities for fans to discover. Check out the full list of MK1 patch notes below for more information.

If you want to pick up the Khaos Reigns expansion for less than the official £40 asking price, then you can purchase a £40 PlayStation Store card for just £35.99 from CD Keys.
