For context, I don’t have access to a controller right now, but I’ve been wanting to play this game for a while. I’ve already beaten Dark Souls 1, Dark Souls 3, and Elden Ring using mouse and keyboard, so I’m used to playing games that aren’t really designed for this setup.

Hi, I just finished Metal Gear: Rising Revengeance and want to play the DLCs. I bought them on the store, but apparently my physical copy of the game is a US version and I can't get the DLCs to work now I've purchased them since my region is Europe.
I thought about making an American Account to gameshare to myself but i don't know if that will even work as when I attempt to make an account it tells me I timed out from the server.
What do i do?

We all know how it ended when raiden got ahold of the Murasama (arguably the best weapon when maxed out) but let's think back a bit. How long (gameplay wise and/or lore wise) would it take? I know raiden dealt barely any damage with his fists against Armstrong, dealing (i think) either 00.1 dmg per hit or per few hits (might even have the wrong damage amount)? AND Armstrong can heal thus making the fist fight last way longer.. and he throws debris at raiden at a certain amount of hp (i think) so would he have to punch it apart or dodge? Either way my question still stands: how long does it take?
