Well I was actually pleasantly surprised by the netcode on PSN.
In this video it was the second time I played DOA5U on PSN and I had a great 5 bars connection both times I played it on.
I thought you mean the PSN is the underworld lol, well it depends really on the connection. With any noticable lag you cant either punish kasumis 1pp as example. Compare to Vanilla DOA5 is the netcode far better!
That's how I called DOA5U online the first time I played it. I was dropping combos, not reacting to certain moves, couldn't punish stuff...almost got used to it now.
