No need to apologize

Ok, lets get this started!
0:10 - first peek at CaC Primary has up to three attachments. Secondary has up to two - one of them is a knife. Looks like up to two of each color perk, and up to two lethal and tac grenades/equipment. And three slots on the bottom, not sure what they are.
Select fire is set on burst - nice!
Looks like he has semtex equipped. Shock nades too!
0:22 - some sort of sonar/xray scope that can see through walls, but pulses like a heartbeat sensor. Seems like he has a flash/stun equipped. Also, a stock on the SMG is optional. Has no blue perk, but two yellow perks...very cool.
0:32 LSAT (an LMG) with a hybrid scope. Also seems like a bouncing betty/mine equipped. Some sort of bullet attachment, with 100/400 bullets, maybe its extra ammo? Also, yellow sight probably means sight customization is back. Then he puts down some sort of turret thats like a heat wave, and he gets a guardian suppress. Maybe like nova gas when youre on the receiving end?
0:43 This time he has an SMG with a grip. One of the mystery slots is filled with what looks like a soldier on a headset. (wtf?) Seems like a rocket launcher as secondary?
0:54 The quadrotors are called dragonfires, and they look fully player controlled.
0:59 This dude has an AN-94 with a sight and grip, and two tomahawks. His secondary looks like some sort of radio or explosive. A scope which paints red diamonds around targets...very cool.
1:15 Now we've got a guy with a secondary revolver called a raging judge, 6 (!) perks, and three mystery slots. wtf are these things?
1:19 Now he's running around with a knife - I think its cause he's literally out of ammo, having shot his last 3.
1:25 This guy is going in with two primaries, two attachments on each, and only 2 perks...no equipment. Two mystery slots...and some sort of battery powered sniper scope, with a satellite icon on it?
1:30 Bolt action sniper rifle....with iron sights. Called a ballista, and he fires through FOUR people at once!
1:40 Shotty and some kind of C4 that needed to be armed first?
1:45 Looks like our new RC-XD is a kamikaze UAV.....
No idea how to explain the ending.....
But yeah, I definitely want to know what those mystery slots were. Looked like soliders in various poses most of the time. If not perks, then what?
No reference at all to cod points either...I wonder if thats still the progression.
