Is there anyway to play Soul Calibur 2 online? kinda like the halo 1 gamespy online trick? All I really want is to play someone who might give me a challenge, I have yet to face a challenge for about 6 months now, and at the last arcade cabinet I played at my character was #1 in every game mode and had the most wins. about 500 more then 2nd place.
Not as far as I'm aware. The reason that they were able to do that with Halo was because it was LAN-compatible. It's a trick called "tunnelling". What you do is you hook your XBox up to a comp and trick the console's modem into thinking it's in LAN mode with another console. You then use your comp to hook up with others over the net. It's basically treated like a "long-distance LAN" connection.
SC2 is not LAN-capable, as far as I'm aware, simply because there's no need for it. You can't play with more than two players at once, and it plays full-screen two-player, so what would the purpose of a LAN be? Unless the XBox or PS2 versions are already online-capable (I wouldn't know, I only own the GCN version), then no, you're stuck playing it face-to-face.
