Bunker

Setup, step by step

1. 1Buy a bunker from Maze Bank Foreclosures — Chumash or Farmhouse keep sell missions close to the city.
2. 2Register as CEO, VIP or MC President, then set up the business from the bunker laptop.
3. 3Assign all staff to manufacturing once you have finished research; split to research first if you still want Mk II weapons.
4. 4Buy supplies rather than stealing them — a full $375,000 of supplies produces about $1,050,000 of stock when upgraded.
5. 5Sell before you pass 26 units if you want a guaranteed single-vehicle solo delivery.

Worth knowing
