Strategies that genuinely change the route
Deluxos–Akula–IAA base
- When
- After Paramedic Equipment, Deluxos and Akula plus their setups are complete.
- Plan
- Intercept data with the Deluxos, enter the Server Farm with the Akula, then clear the IAA base and defend the War Room in the finale.
- Trade-off
- Vehicles speed their setups, but the finale crew must slow down in corridors and maintain one defence line.
Plan for the selected team: DUO

- Missing equipment or vehicle blocks its paired setup and breaks act order.
- Correction
- Return to the incomplete pair on the board and finish its prep before relaunching the setup.
Split Server Farm
- Consequence
- An alarm or split traps the operator among patrols and delays later terminals.
- Correction
- Return to the last shared entrance, remove the nearest guard pair and resume with the operator in the middle.
Open War Room flank
- Consequence
- An unguarded door lets a wave interrupt defence and overwhelm the objective player.
- Correction
- Close the nearest door with fire, revive behind the console and rebuild the defence ring from the centre.
Pre-launch checklist
All three prep–setup pairs are complete on the Facility screen.
The data operator and War Room defenders have separate assignments.
On the Facility screen complete Paramedic–Dead Courier, Deluxos–Signal Intercepts and Akula–Server Farm as pairs.
The Akula drops the crew at one point and the data operator moves between two cover players.
Assign entrances and do not chase enemies beyond sight of the active station.

Expanded informational overview
Guide scopeThis section organizes the complete cycle: requirements, phases, figures and dependencies. The detailed operation flow is in the walkthrough above.
04
How the full cycle works
This section complements the walkthrough with full-cycle dependencies: unlock, preparations, finale, settlement and the next available attempt.
Unlock
Base requirement: Facility. Minimum entry cost is kept separate from the setup fee.
Plan configuration
Available approach, target, difficulty and team choices determine later costs and payout distribution.
Preparations
The model's full time includes required preparation; optional items trade extra time for a safer run.
Finale
The result depends on target or pool value, participant count, possible losses and bonus conditions.
Settlement and replay
After deductions, the pool is distributed using the payout model. Group heists have a 48 min wait after the finale.
05
What affects the result
The min–typical–max range accounts for a variable target, loot or difficulty where applicable.
The setup fee is deducted before the net result is calculated.
Player count and NPC crew fees can change the host and each partner's payout.
The model compares 1 hr 15 min / 1 hr 45 min / 2 hrs 40 min, not the finale alone.
Main strengths
- High payout per completed cycle.
- Clear split between preparation, finale and settlement.
Constraints
- Entry and setup costs reduce the first return.
- The result depends on team size, cuts and cooldown.
