DMZ rules: Gunsmith unlocks at DMZ Level 10. Extract a Weapon Manual to unlock buying that base weapon (it also pays 5,000 DMZ Cash). Base weapons start with no attachments: buy up to five attachment slots, each costing more than the last, plus the attachments themselves. The Apex slot opens after leveling the weapon. Looted Hajin weapons can carry up to eight. Fail to exfil and the weapon is lost.
