YOU CHEEKY BASTARDS

DICE, if I'm right about this theory, you're the most player friendly developer around right now. You see, data miners found a gun called the Perino MG in the game files for an upcoming update. Now, that happens all the time around DLC time, but if the Perino is coming in as part of the Russian DLC, then why has it not been added to the CTE where people can test its balance? Speculation is that it's a new elite class, but that doesn't hold much water as it would be no different from the Sentry. So I believe I have cracked the secret: the secret additional reward for completing the three summer community missions, in addition to the known rewards that are the dogtags, XP boosts, and the Arditi Dagger, is none other than the Perino MG! I have come to this conclusion for three simple reasons:

1. If it were a regular DLC weapon it would be in the CTE for testing and we'd know how to unlock it.
2. We already know we are getting a melee weapon for the missions, so we'd be completely underwhelmed by a "secret surprise" of anything short of either another exclusive melee weapon or an actual exclusive gun.
3. Both the Perino MG and the Arditi Daggers follow an Italian weapon theme. Maybe a coincidence, maybe not.

If I'm wrong, then my firm second guess is that they'll give us an exclusive legendary skin that can't be earned in battlepacks, which I know some players would be even more excited about, but I'd bet money on the secret reward being a weapon and this is the most likely candidate judging by the evidence. Hope you enjoyed my conspiracy, let's see if it comes true.
