I'm talking first about this guy, featured in this match in BLOPS2 using invincibility/invisibility.
if you Google the Gamertag, you can see complaints dating back to mid-April. This account is still active, the guy played Halo 4 and BLOPS2 last night. If you check the stats on Elite or Waypoint, they are ridiculous.
The NEW culprit is also on both BLOPS2 and HALO 4

I wonder how long it'll take before these people are dealt with. Meanwhile, with each day that passes, more people are quitting the game and saying, "Screw Halo/BLOPS2, it's loaded with cheaters. I'm not coming back to this."
