How Research Works
The Research Process: Your bunker staff automatically conducts research when you’re online or offline. Progress continues passively, but you must assign staff to research rather than manufacturing (in bunker settings).
Optimizing Research Speed:
- Equipment Upgrade: -40% time reduction ($1,155,000)
- Staff Upgrade: -25% time reduction ($598,500)
- Combined: Research completes in ~3.5 hours per project
The Random Factor: Projects unlock randomly—you cannot choose specific items. This means getting desired items like Oppressor missiles might require completing 20+ other projects first.
Fast-Track vs. Patient Grinding
Patient Approach (Recommended for Budget Players):
- Dedicate staff fully to research
- Complete one project every 3.5-5 hours
- Run supply missions or purchase supplies ($75,000)
- Total cost: ~$3.8 million in supplies
Fast-Track Method (For Wealthy Players):
- Instantly complete projects for ~$225,000 each
- Total investment: $11.5 million
- Time saved: 200+ hours
- Best used selectively for must-have items

Step 3: Keep bunker supplied (buy supplies for $75K every 2.5 hours)
Step 4: Fast-track only critical unlocks when they appear
Step 5: Let remaining research complete passively while doing other activities

FAQs
Q: Can I choose which research project to unlock next?
A: No, bunker research projects unlock in random order—you cannot select specific items, which frustrates players seeking particular upgrades.
Q: Does research continue when I’m offline in GTA Online?
A: No, research only progresses while you’re actively playing GTA Online, though you can do other activities while research runs passively.
