QuoteThere are those of you doing things you shouldn't be in Halo 3. Some of you have gotten a little too famous for your own good. This ain't a church and there is no redemption or salvation once you have been judged. Apologies are now officially too late to save you.

    The storm approaches.

    Love, Bungie

If youre a cheater or an online trouble-maker in Halo 3, Bungie has it in for you. Last Friday they posted a message—more of a threat, really—saying that they know who you are, and theyre not happy.

Lots and lots of people stats padding etc online at the moment and quite a few found some ways to glitch

Its the network glitches that get me tbh, sudden lag then all dead.

a glitch or a DDoS tho?

Both I think, Ive only ever had it happen to me a couple of times.
Im thinking more glitch though, as most computers are pretty robust against DDoS I think, what with routers etc.
