During the development of a game, to better test their products and access certain functions quickly, developers implement debugging tools. Well, it seems that the guys from Housemarque forgot to disable those from Returnal!
Thanks to this forgetfulness, it is possible take advantage of the same cheats employed by the developers during the production of the roguelike. How? Simply by connecting a keyboard and using precise combinations of keys. For example, by holding Shift, Control, Alt and a number from 1 to 0 you can drop weapons at their current level and choose the preferred one in case of death. With Shift, Control and 4 you are teleported to the ship without losing energy, money, keys, artifacts, adrenaline levels and weapon effectiveness, with the ability to access the shop. See for yourself in the video at the opening of the news, whose author advises not to use the 3 or 7 keys as they generate freezes. Further details can be found in a Reddit specific topic.
I cheat code they work from version 1.00 to version 1.03 of Returnal. These are almost certainly non-public features, so it is highly likely that they will be removed in one of the next updates. Meanwhile, debates continue over the limitations of Returnal’s bailouts.
