So far it looks like all the gun upgrades are unlocked by completing challenges and all the guns are unlocked through story missions. Is this the only way or can I get them through Guerilla mode the way R6 Vegas lets you unlock guns through ranks in Terrorist Hunt? --- "We, Jaina, are the New Jedi Order... and this is OUR war." -Kyp Durron
far as i've seen geurilla mode you only get weapons dropped in crates and you just pick from whats available there. Then the campaign weapons are unlocked by doing campaign, and adversarial stuff is unlocked by doing adversarial. --- XBL GAMERTAG: xXxDSMer Live Free or Die Hard.
There is 2 mby 3 weapons unlocked by doing guerilla mode though. kard pistol and saiga shotgun come to mind. unlocking those by playing guerilla mode makes 'em available in the campaign --- XBL GAMERTAG: xXxDSMer Live Free or Die Hard.
Skorpion SMG by finishing a stealth wave with no alerts, I think. Easy to get in the office level, just lay prone and use your silenced rifle. --- The Official Yuna of the Dissidia 012 Duodecim boards :D PSN: XWintersHowlX
