'im on fire' - dangerous screenshot?
Last night, we got a message from a pretty trustworthy Halo 3 player, discussing an incident that occurred in a game played a few minutes earlier. Before the veto countdown had finished, the opposite team sent messages to all players, and one of the recipients opened the image file included in the message - that player's 360 froze, removing them from the game (and leaving the other team with a 4-3 advantage). The file being blamed as the culprit is on Bungie.net - but is not viewable online. The thread associated with the file suggests that others have had the same trouble, or have used the file to CAUSE the same trouble - and this morning, the warning showed up on our forum, as well. I'm sure Bungie is looking into the issue - but in the meantime, I'd recommend that you not open screenshots sent to you by unknowns while you're on your 360. (Louis Wu 17:01:16 UTC)
