Applied a gravity force to the player

hi, i want to recreate the system in this video but i don’t know how, like it’s said in the comments:“The player is rotated. Instead of using the engines gravity, a force is applied to the players down vector”, so i have to attach a force to the playerhttps://youtube.com/watch?v=6uxzkcQsf_Y

but also i need an input to rotate the player, i wanted to make a similar system to the inspection system, you can rotate the object from all direction but here i would be the player
