So for the past week now, whenever I try to go online with Killzone 2 I either get the error code 10002 or -10.  It's a shame because Killzone's multiplayer is amazing, but, I cannot play it. It is not my connection, because every other game on my PS3 works fine online, and it is only this game that's acting stupid. I have no idea what to do and this whole experience is turning me way off from Killzone. I'm so pissed I don't even want to play the single player campaign. Is this happening to anyone else?

Not happening to me.

That sucks, it's working for me fine, hopefully it's just a problem with your internet that will be worked out on it's own.

"Killzone 2's online Multiplayer has been flawless for me so far. It must be a problem on your end. Perhaps you could provide some more details (like ISP, kind of connection, list of games you have that DO work, etc.)?"

i have no problem what so ever. i find the ps3 wireless connection to be unreliable, so i've been using my long ass ethernet cable, and have not experience any problem ever since.

I would say maybe try using an ethernet cable rather than Wi-Fi and see if that doesn't help at all. Otherwise go to killzone.com and check the forums there

It is probably your router. I had similar problems with Resistance 2 where it was only that game I could never connect to. I traced it down to my router setting up a firewall that blocked out the Resistance servers. Just in your case it is blocking out the Killzone servers. You should try contacting your router's services and figure out how to configure your firewall so that it will except the Killzone servers.
