Operation: Clean Sweep

 Operation: Clean Sweep is Eggman's latest plan. It is started when Eggman inserted a Chaos Emerald in the EggDome's central reactor, powering it up and launching the new Death Egg. When Sonic and Sally infiltrated the Death Egg, they were stalled by Silver Sonic III. Once Sally realized they were being stalled, she went ahead and got shot multiple times by a gun that came out of the wall. Eggman then fired the now charged weapon, which erased everybody's memories and altering time and space, officially starting Operation: Clean Sweep.(ASB, StH: #224, #225)
