That it would, assuming you can get the lobby screen to appear. Or having it glitch up and bringing you back to the main menu. Repeat the log-in screen and try to get a lobby screen again only to have it freeze up and no buttons work, with the only way out via exiting to the dashboard. Worse would be when it glitches in the online menu and just freezes the 360. Then if you can connect to a host room. Then if you don't get dc'ed once everyone readies up and the game loads up. Or after it loads and you choose a character and it moves on to the map screen. Or simply getting dc'ed some odd minutes after joining and playing through a level.
Yeah, and might wanna becareful with the Alien Hominid character and the pitchfork, unless you want to rid of his gun forever or like restting stats you've built up with him.
