I'm not really liking sandbox (or at least access to the cheats in sandbox) being locked behind the story mode right now in the current game state. I'm someone who's really interested in the more tame parts of the game and want to save the story for later when I get the hang of the mechanics better. I am playing in infinite mode right now. I was trying to get the key card from the bunker and moved it accidentally. I didn't get an error notification that some people talked about online, but it was out of view in my main save file. Unfortunately, my game saved and I couldn't access a previous save. I would have really liked to just spawn in the item and moved on, but since I haven't unlocked it through story, I wasn't able to. This gave me about a full real life day worth of frustration on googling and figuring out how to get a key card to myself, which I ended up using the mailbox from a new save. It didn't feel worth it in the end and once I got the key card, I was just exhausted and closed the game for the day. Possibly in the future these cheat commands can be toggle and not hard locked behind achievements because not everyone wants to play the story right off the bat.

I was also initially salty about it, too, but I soon came to see that sandbox has it's reasoning to be locked behind at least a certain point of the story. This is an atmospheric simulator horror game, and sandbox I feel gives far too much freedom to the player to just be unlocked right off the bat.
There is a level of discovery in the game that I feel instantly having sandbox unlocked would potentially discredit. Normally by the time you unlock sandbox, you have likely experienced enough of the game and it's story content that you are "worthy" of having access to the ability to mess around with it. But if sandbox was instantly unlocked, rather than experiencing an discovering everything in the game naturally over time, a new player could just go through it all at once with cheats.
Additionally, sandbox doesn't let you move items outside of sandbox saves without exploits, so you wouldn't have been able to do anything with the spawned keycard anyway. Unrestricted cheat access outside of sandbox does exist as one of the Patreon supporter rewards.
