Far Cry 5

I found a reliable endgame spot for this for anyone who has trouble finding enemy vehicles after having liberated everything.

All you have to do is go to Rye & Sons Aviation, it's in the far south of the map. There you should encounter a quad bike with one or two enemys heading for you from the road on the south side right next to the hangers. When you die they instantly come back for you so you can try this over and over again to get the five kills. If for any reason they don't show up for you try fast traveling there a couple of times. It was night time for me when I encountered this so maybe it will affect their spawns.

What you have to do is first of all have the perk "Saboteur" unlocked. It costs 7 points. After that go up to the front of the quad and hold . Then quickly run away from the bike in the opposite direction. That way the enemys usually take cover behind it. It may take you a couple of tries and the achievement sometimes wont make any progress eventhough it worked but keep trying and the achievement will be yours.

There's an achievement/trophy for getting five kills by sabotaging a vehicle, and having it blow up and kill an enemy. The game is a bit finicky when it comes to counting these kills — it didn't work with an ATV in another spot, for instance — but I found a foolproof place to grind these out.

First, make sure you have the sabotage perk and make sure you have the difficulty set to easy. I'd also recommend crafting the homeopathic for incurring less damage, but that's up to you.

In Faith's region, go to the trailer park to get Sharky, the flamethrower-wielding Gun for Hire. Talking to him starts a mission called "Burn, Baby, Burn", where he lures cultist Angels in by playing the song "Disco Inferno". You're then tasked with clearing out the Angels.

You can try the trick during the first wave, when it's just a few angels here and there, but I found it worked best when Sharky gets overwhelmed and you're required to shut off the speakers in four different parts of the trailer park. At this point, swarms of the Angels come out and keep spawning until you switch off the last speaker.

Directly across from Sharky's perch is a vehicle spawning station. Once the Angels start to swarm, make a beeline for the vehicle spawn and request a vehicle. I just happened to choose a tractor, which worked out great because it's larger and will help shield you from the Angels. Go to the front/hood of the vehicle, hit to sabotage, and then run in a circle around the vehicle while the Angels are swarming. You might be able to get multiple with one explosion, but the Angels have weird hitboxes — the amount of damage to kill one may not be the same amount to kill another. Luckily, you can just repeat this method to get your five kills, shut off the speakers, and complete the mission.

I tried for this after the end game and I found that if I traveled to Joseph's Island A boat would spawn always by the Docks, So i threw an explosive to lure enemies towards me and then sabotage the boat. It was also pretty useful as you can push the boat towards enemies,

i just unlocked this during the campaign in faith's region while helping guy marvel with his movie set side mission. eden's gate will drive in speaker trucks that will awake the angels and guy asks you to destroy them. i ran up to one and sabotaged it (after unlocking the perk), then ran around the truck waiting for it to explode while the angels chased me. i was knocked down but simply used a medpack then waited for the next truck to arrive. rinse and repeat. you get 3 trucks to attempt this; i got 5 total in with 2 trucks. i also used an ultimate survivor syringe to be able to withstand the angels attacks while i ran around waiting for the truck to explode.
if you die i think it still counts your kills.
hope this helps someone else!

Another endgame area I found that works really well for this achievement is the US Auto Outpost, located just northwest of Fall's End. There is a truck with a bunch of speakers in the bed that will always be in the outpost. The way I did it was to run in, Sabotage this truck, take cover and let it explode, usually killing 1-2 enemies, then fast travel to Hilgard Electric Power Station just southeast of the outpost which resets the outpost and then rinse and repeat. This method worked really well for me, I hope it does for you too!

I tried most of the solutions above, but to no avail. If your like me, you did almost everything before you finished the game. After running around the board for hours looking for cultists, I finally had to click on the Outpost Master in the options menu. It reset all the outposts to hostile, and I finally got it throught that. Good luck.

- The best way I found was to approach a cultist vehicle on the road and run up to the hood and Hold to sabotage the vehicle (you can heal with at the same time to stay alive).

- Once they jump out keep one close to the truck, I let him punch me they I just kept him between me and the truck until it blew up

*Buy the "Saboteur" perk from the skill tree early in the Campaign, then just sabotage vehicles throughout game-play in order to unlock this naturally*

The easiest vehicles to guarantee a kill seem to be those with mounted machine gun turrets. The driver/passenger will jump out of the vehicle buy the guy stood on top with the MG never seems to run off when you have sabotaged the vehicle, just make sure none of your guns for hire take him out

Go to Johns Region-Holland Valley. Along the right border there is a blue pin called Hope Valley Clinic. Go there, look down the hill. Right when you spawn two guys will drive up the hill in an atv. Sabotage it, as long as you stand next to the atv the enemies will stand there as well. Fast travel somewhere else then back to hope valley clinic and they respawn. 3 times of this should finish it off.

I traveled to The Grill Streak in Jacob's region. straight across the river are 2 trucks where some Peggies are shooting at a bear. walking straight for them crouched, I was able to sabotage both trucks, fast travel back to the Grill Streak, and did it again. 5-10mins

Something I never saw any of the other solutions mention is that the enemies need to be engaged in combat with you/aware of your presence for it to count. I got about 8 or 9 kills total but a few of them weren't attacking me/aware of my presence when they died.

Nonetheless, if this is, say, the last achievement you're doing and you're struggling to find any enemies, fast travel to the Dock at Joseph's compound. Circle around to the front of the base without being detected and enter through a hole in the northeast corner. There should be a truck by the front gates with an enemy pacing nearby. Sabotage the truck, and a few seconds before the bomb goes off, shoot a couple rounds at him. Back up as he engages you and he should get blown away. Rinse and repeat 4 more times.

I found a repeatable location with enemies to get these three achievements:

Squash and Run
Opportunity Knocks
Explosive Surprise

In John’s region / Holland Valley, towards the top left of his region (middle left of the overall map), there is person that will give a story mission named Merle Briggs. He is located at the fast travel location called Silver Lake Trailer Park
He is being held captive with 4 guards, close to a vehicle, all within a close vicinity of each other.
Because he needs to be freed, you can attempt anything you need and then fast travel back to the location with the enemies reset.
I find this MUCH easier than attacking an outpost

Explosive Suprise:
You can sabotage the truck (you might have to have the enemy come closer to it) without being seen.
If you fail, you can just fast travel back to the same location and try again

Opportunity knocks:
I recommend highlighting the enemies with your binoculars first - it never seemed to work for me when I didn't.
You can only get 1-4 per try, but distract one enemy at the starting point (from fast traveling) and then the enemy on the far left. After those two, you can try to distract the other 2 "middle" enemies.
I does not seem to count the same enemy twice, so after a max of 4 enemies distracted, if you fail, or if nothing registers, you can just fast travel back to the same location and try again.


Squash and run:
Grab a vehicle and drive up to the location, or grab the truck and run over the 4 enemies.
Once they are all dead, or if you fail, you can just fast travel back to the same location and try again
