I used C2 a lot and could just open multiple tabs to test out MP, tab 1 is player 1, tab 2 is player 2 for example. But with C3 it just refreshes the first tab.
I tried opening 2 different projects, but still it just refreshes unless I get one to have a popup window. But when I do this, the tabbed preview won't connect to the MP server.
Does anyone have some advice on how to test MP games? I know how to build them, like I said I used to play around with it a lot on C2, but now I don't know how to actually test 2 different players logging in.
