Can you make a fully multiplayer game with unreal 4? How much do you estimate it will cost to make it multiplayer compatible? (cheapest possible)
Cost as in $$$ or as in TIME?
To answer your first question, if you’re not trolling, YES you may make a fully multiplayer game in UE4
Docs to start off: Networking and Multiplayer | Unreal Engine Documentation
Multiplayer Shootout | Unreal Engine Documentation
Videos: - YouTube
To answer your second question, seeing how you wrote cheapest, that is entirely up to you and your team (if you have one). It can be from FREE all the way up to $999,999,999,999,999,999.99 If you are so inclined.
Thanks for the help.
