Boring Machine: Tunnel Into the Vault on Aggressive
The Boring Machine is the alternative Aggressive entry. Instead of crashing through the casino front doors, you tunnel up from the sewer system beneath the building. You spend less time fighting through the upper floors, but the prep itself is intense — escort an oversized drilling machine across the city while every police unit in Los Santos chases you.

- Drive the flatbedThis is the hard part. The flatbed is slow, the route is long, and Merryweather convoys ambush you at multiple checkpoints along the way.
- Defend during ambushesStop the flatbed, get out, eliminate the ambush, get back in. A teammate on a Buzzard makes this far easier.
- Reach the ArcadeOnce at the Arcade entrance, the prep registers automatically.
Tips & Strategy
- Duo run is much easier — one drives, one provides air support.
- The flatbed is durable but slow. Do not try to outrun ambushes, fight through them.
- Skip the Boring Machine if you prefer the front-door Aggressive run. The default Aggressive entry works fine.
