Bonus Episode 1 stars Moria, she is with a 'mysterious old man', apparently. She has a slightly different costume in this episode than her main costume, wearing gloves, a scarf, etc. Apparently, in this episode/game mode, it's all about survival. You need to hunt animals (rabbits, birds, snakes, rats) to get rations, and if you have no rations when you die, you get a game over and have to start all over. Says you can only quit when you get to a checkpoint, if you quit when not at a checkpoint you have to start all over. Some new game mechanics, seems to be a lot more punishing and describes itself as 'a test of survival skills".
The second bonus episode stars Natalia, apparently in this she's looking for a friend of hers, and for some reason in this game mode you work with another Natalia, who looks a lot like Natalia but has different hair, a necklace, and wears a black dress, but who's name is also Natalia. This game mode and episode looks absolutely weird in the texture shots for it, it shows the island like it's super psychedelic or something, with purple and pink fog everywhere. In this game mode. the White Natalia must absolutely not be spotted by enemies, if she gets spotted, it's game over. However, the Black Natalia cannot be sensed by enemies at all, and can walk freely, but cannot interact with anything in the world. Have a big open sandbox level, and apparently need to find letters and photos with clues of where your friend may be.
