Just Cause 4

I also didn’t have it pop right away. Properly backed out to main menu, closed the game, reopened it, then quickly completed a rampage by letting the time run out. Popped after that.

Excellent tip from Tenreth. I had the chopper from the Danger Rising DLC and used that on all of the Rampage courses, made them trivial. However you will still need to use daredevil cars for Runs and Survival Runs.

For an easier time with twisted alley. S rank Run : Nightbridge first and Get a Fully upgraded Sol Velocista Supply dropped before the start of the race.
It’s much better than the one sitting at the race start.

Just an addition to the copter tip: You don't need to grab another vehicle once your heli runs out of ammo, just dive out of it and press B when it prompts to and you'll find yourself in a new heli with full ammo again.

Just incase anyone else didn't realise flags build multiplier in the runs I thought I'd mention it.

Use either the siege helicopter, or your favorite S rank car supply drop, depending on the event type, to make this go smooth. Twisted Alley is only event you'll cut it close on with supply drop assists. This was my favorite DLC of the bunch.

Yes Mobius Evalon has stated. Using the Sol Velocita fully upgraded is a superb choice. I had no problem getting rank S on all races. Thanks a million.

I just held down the fire button on the front facing weapon the entire time I was driving the course and S ranked the runs by accident.

The fully upgraded Sol Velocita seems to be the best candidate. All the way at the northeast corner of the map, just south of Islas Kaupyes, is the Nightbridge event. S rank that one first. Use that car in every run and survival run, holding down LB the entire time you're driving and tapping RB every time the rear grenade launcher refills. If you run out of ammo, bail the car and use B to respawn with a new one.

I got this using the Brawler Mech for every course. First try every time. It’s extremely easy to destroy everything in your path and the mech is pretty fast and agile. You can dash upwards and diagonally etc plus with jump you can really get around. Just keep punching away nonstop!
