I played CoD 4 on the DS back in the day as well! Agreed the double tap iron sights were terrible, but I was surprised at how much they preserved the setpieces of the game.
Have you played Metroid Prime Hunters? Thats probably my favorite shooter from the DS area. The single player campaign can be backtrack-heavy with no real plot, but the shooting is fun and the multilayer mode with bots is a really good time!
Try the Submersed mod, it adds full motion controls!
Im working my way up to Xeno 3! But yeah I love Reyn, such a fun character
Pathologic 2 is a game that makes you feel like the entire world is against you. From the moment you start the game you're presented with a scenario in which you've already failed to stop the deadly plague infecting the city, and you get a chance to do it all over.
You are Artemy Burakh, a surgeon coming back home to his home in the Russian Steppe at the request of his late father. From the moment you arrive in town, things are off. You are quickly branded as a criminal and must hide away or risk being attacked by citizens. Slowly but surely, you keep encountering strange things in the town: an impossible spire stretching into the heavens, a building where an infection has seemingly taken over the walls, a band of children who have broken away to form their own gamg, and the plague itself speaks to you - warning you about the devastation to come.
The game is brutally tough. It has difficulty settings if you struggle too much - but the intended difficulty is meant to crush your will to continue. While fighting off the plague you must manage your own hunger, thirst, and health. Which becomes increasingly harder to do as the plague grows in strength. In addition - at the end of every day the game randomly rolls who in the town gets infected with the plague and for those already infected they could possibly die. Everyone, including you, and I mean everyone in the town has the potential to die. You are tasked with keeping them alive.
On top of that the game is an excellent journey into the psychology of those you meet, and comments on the blend between the supernatural culture of the steppe and the growing industrialization of the city. There's so much stuff there in the game (mind you there is some jank), and its the kind of game I think about all of the time. Also the soundtrack is beautiful and haunting, with the perfect emotion for each scene.
I just had my therapy session yesterday and she was so cool, said she's been involved with the trans community since the 90s. She was so supportive of me coming out to her
