Alemismun: Today I had a discussion with my friend, he was talking about CP77 so I decided to hop in and ask him if the story would adapt to the players actions, such as killing an NPC.
He answer with "there are multiple endings" but that didnt seem like much of a response to me.

I mean, in that sense, so does GTA 4 and thats quite a liniar game.
Theres a specific mission where you can choose to save or kill some guy and then the story changes depending on that action. But thats rather cheap, I meant it in a fallout kind of way, as in, you can kill any character at all at any point and the story will just go on with it.

This question makes me quite curious because CP77 seems to be trying hint at every corner that player agency is very important to the game, yet I have not seen any actual... proof.
In the 40 minute demo, most actions were rather standard and expected... What would have happened if you shot the girl in the tub? can you kill your companion? what about just going on a murder rage and killing every NPC, what happens then?

TL;DR I wanna know to what degree the player is given freedom to interact with the story, is it an immersive sim? or is it like GTA were any drastic move results in a GAME OVER screen?

DarklordGriffen: Currently unknown if you can just randomly start shooting important NPC's but they have said if you fuck a quest up the game won't give you a game over and you will have to push forward with the consequences.
Like for example if you do an escort quest and whoever you are escorting dies, the game will not give you a game over screen, the game will try to react to the fact that you let said person die
