CVG has the disappointing news, originally reported in the pages of EGM, that online co-op play will not be available when Halo 3 launches this September. In the game the second player would play the part of the Arbiter character, but fans will only be able to complete the campaign cooperatively via LAN or split-screen. Bungie stated the possibility still exists online co-op could be patched in at a later date, but significant hurdles stand in the way of the feature: "'We're not dumb,' says Bungie's Frank O'Conner. 'We know that people want it and we're trying to make it happen. I think the biggest problem for us for online co-op is that we have a situation where you can be in a Warthog with five troops, almost a mile away from the other player. That's a significant challenge. And there's lots of design things you could do to prevent that from happening, but they would make it not feel like Halo anymore. If we can make it happen in a way that works well, we will - and if it works badly, we won't.'"
