Multiplayer Co op game? Listen Server?

I am making a very simple multiplayer game up to 4 players.
I would like to be able to play with friends over the internet, and not just LAN Mode.

Would I need to use “Online Subsystems” such as Steam, Xbox…etc. Or can it be done without any Online Subsystems?
I dont really have the option for a Dedicated Server. So think I need to use a “Listen Server”.
Where a Client will also be Hosting as the Server.

I would like to know if it would be possible to Host a very simply multiplayer game over the internet (not LAN mode)
without using a dedicated server or online subsystems?

Thank you for any help

You can just join another game via IP. There should be plenty of information floating about online.
