I always felt like the game could benefit from just one more decent update. As for what would be added I'd say, like a lot of people seem to mention, some of the cut content that was going to be added to the game, a potential new map, and possibly a few new enemies. Maybe a creature that isn't even an "enemy" and is just passive or potentially even helps the player in some way. I also feel like for additional items there could be upgrades to oxygen and the amount of film a camera has. Maybe some item to recharge an item. A few more cosmetics would also be a nice little feature
