Sub Quests

Sub quests are optional side jobs from Zac. They don't block story progression, but they are the fastest source of extra Money, XP, and rare rewards like Attachment Boxes in the early-to-mid game.

All sub quests are accepted and turned in at Zac in the Hideout. See the Task system page for submission point rules.

Sub Quest List

Quest	Map / Location	Objective Summary	Reward
Scavenger For Supplies	Any map (Warehouse recommended)	Loot 15 boxes/crates	Money + XP
Stock Up	Delivery	Hand in a set of consumables	Money + XP
Viper's Last Shot	Crossroads (Bunker 04)	Kill Viper	Attachment Box

Tips

• Scavenger For Supplies stacks with everything else — if you're running Warehouse or Crossroads, do it in parallel with Main quests.
• Viper's Last Shot pays the best per-attempt reward: the Attachment Box is worth far more than individual attachments in trade-ins.
• Sub quests can be stacked in a single raid as long as the objectives are in the same area. Always check your active quest list before deploying.
