Me and my friend discovered that we could reload the weapons on the third mission because the game doesn't explain and have it on the same button as the action and close combat. Just that was enough for the game to prove how bad it was, but not satisfied, the game crashed right before we complete and it didn't saved, so we will need to play from the start of the chapter

Also, the sensibility on the configs is basically just a bar with numbers because it doesn't change shit
