Road Fury (EP)

The difficulty of the game increases with each boss killed, and at first it will be difficult to kill 5 bosses in one life without upgrading your car.
The game starts with a simple zero level and only one blue car is available. For the first blue car, you need to save up $30,000 for maximum upgrade of armor, main and additional machine guns. This will take at least 2 hours. The game starts from level zero and only at this level you need to save money. The main thing is not to kill the first boss of the game! When a boss appears on the road, just pull up to the side of the road and let him shoot you.
After death, you will receive $220 - $280. The bonus is based on the distance traveled and the number of cars blown up. Always try to shoot the blue cash-in-transit vehicles, as you can pick up $20.
When farming money, upgrade only the main machine guns and armor of your vehicle. If you start upgrading additional machine guns, you may accidentally destroy the first boss. Upgrade additional machine guns to the maximum with one purchase. Copy your game save to the PS+ cloud or USB when you have fully upgraded your armor, main and secondary machine guns. Now, your goal is to kill 5 bosses in one life. If it doesn't work, close the game, load a backup save and try again.

PS You can stick to farming money, save up another $10,000 and buy the maximum upgrade for the laser. In any case, you will need to purchase all upgrades for the trophy.

I'll probably fix it on a blue car. Because the green car opens at level 8, and the blue car is available from the very beginning.
