Setup First Person

Hello , I am going to create a First Person game , and I am having difficulty setting up my first person. I can do the arms thing with the First person , but I want No hands First person like in vanishing of Ethan Carter. I want to have a dot in the center of the screen, which will be able to pick things up.

Any help will be highly appreciated!
Ps, this will be my first planned game.

Thank you

Got it! .
Thank you
