Custom games?

Does Halo 5 have custom games? Or are we still limited to everyone having the same traits? I really hope they have leader traits for juggernaut and stuff maybe like slenderman. Did they add in infection without the weird -Yoink- flood things that they did in halo 4 where we can actually edit player traits? Or is it just forge for competitive gaming solely?

We have custom games but they took huge steps back words thanks to the lack of settings and gametypes
