Just Cause 3

First do the Boat Invaders challenge and try to get 5 gears on in order to fully upgrade the eDEN Spark.

As for the challenge, here are the scores:

- Transport Boat : 500
- Corvette : 1000
- Heavy Patrol Boat : 2000
- Light Patrol Boat : 3000
- Helicopter : 8000 (!) (as soon as they spawn, give priority to these)

I wasn't able to get the full 5 gears the first round.
But with a few gears obtained the first round and the MODs set to active, it became easier to get 5 gears on this challenge.

EDIT: as pointed out by The SCHWARTZ 00, you don't need a fully upgraded eDEN Spark to get the achievement.
I personally felt it made things easier.

Then, I headed to Ponere to re-oppress the city as it was already liberated.
But in fact, any settlement where you can gather enough enemies together, will do.

You have to kill at least 10 enemies with a single eDEN Spark Strike (by holding ).
You can direct the spark strike with , and still move around with

I personally chose a police station since a couple of enemies come to the open area once a few things are blown up, and as soon as a few are killed, some more spawn through the door as shown in the vid I made.

EDIT: another appearantly good spot to get this achievement on, brought by SiegfriedX, would be Guardia Val De Mar V.

Again, any settlement will do as long as you can have 10 enemies to kill within 12 seconds (duration of the Spark Strike)

Any suggestions to improve this guide are welcome.

Thanks for voting thumbs up if the guide was helpful.

Good luck!

The EASIEST PLACE to do this is during the penultimate story mission The Shatterer of Worlds, Act 3 Mission 7. It's far easier than any town or base, so if you haven't yet done that mission, bring along your eDEN Spark.

During the second phase of the mission you are told to hack or destroy two SAMs which protect the air space above an open field that is absolutely littered with soldiers and armored vehicles. There are about 15 soldiers all lined up, not even counting the ones in vehicles. You can easily lay them all to waste in one go.

As for upgrading the eDEN Spark, of course it makes sense to upgrade it as far as you can, but this spot is so perfect even the vanilla weapon will do. What will help the most is reaching the 3rd gear in the Boat Invaders challenge to earn Power Up, which extends the spark duration to 12 seconds.
