This strategy is for quickly gaining loads of money in Brigador, to unlock everything.

The strategy needs the following to be unlocked:
Precursor James (pilot) $100,000,000
Varlet (a corvid tank) $20,000,000
Black Hand (small size weapon) $500,000
Audio Kinetic Pulse (special weapon) $5,000,000
JOY BUS / HELL RIDE (map) $5,000,000

In total, this will cost you $130,500,000
To get this much, just play through the campaign and you'll have enough by the end of it.

To summarise the strategy:
1) Start JOY BUS / HELL RIDE with the above equipment
2) Hope you spawn on the right side, if you spawn on the left then hit restart
3) Start moving, turn to towards the tank
4) Open fire with the audio kinetic pulse and both black hands on the tank
5) Continue to turn and run into the escape wall
6) Hurry through when the wall drops as the tank dies, the mortar from the tank should take out the first torpedo
7) Repeat as needed

Reasons for the equipment choice:
Precursor James multiplies payout by 5x. The varlet multiplies it by 10x. The map choice is because the only objective is right next to the spawn and an exit. The black hand and AK pulse can attack immediately through walls, so you can kill the objective within moments of spawning.
