I blame the sounds on Host-A.net as there is no reason it didn't work, but 2.0 should have them.
As for the picture, it only features the pistol, shotgun, and SMG based weapons with the exception of one rifle based weapon on the side of the picture (the green one).
Color Key for the new set of weapons for those who may have missed it:
Red - Pistol (Con deagle por favor)
Orange - SMG (New chasis ftw)
Yellow - Shotgun (Yes, the thing with the barrel is, infact, a shotgun.
Green - Rifle (Based on absolutely nothing in particular)
Teal - Demolitions (Shoop da fukin whoop)
Blue - Snipers (yes I realise they are technically rifles but you will notice a significant differance between this and the green ones)
Purple - Misc (The return of everyones favorite Proto-16 along with a new nifty overpowered peice of kick-ass)
