Deadfall Adventures

The quickest way - Pyramid map.
8 Duru in 4 minutes.
They can be killed when they are located on the wall , wrapped by lianas, and it is important to find the correct angle for shooting.
Tactics: First, you need to kill two of them in left and right pass, then two which are the most distant. After that there will be four remain on the one wall.
In the second wave, after killing four, perk with machine-gun will be opened - kill the rest (others) by it.
You can get ammo in boxes, one person will get full ammo. In the break between the first and the second wave you need to get full ammo.
If you play alone - there is no boss in the second wave.
This achievement takes more than 12 hours.
Good luck.

I recorded a video based on Andrey7234i's description.

(Edit: Only public survival matches count for killing the Daru. If you are playing with other players , killling a daru will only count for the player who killed it.)




And a Big thanks to Koenigstefan91, who showed me how to kill the Daru in this way.
I hope that helps

I tried the other maps in survivor and personally preferred mayan tombs over the others.

Only using regular guns, this is how many daru you can kill on each map
(didnt try the two perk guns, they might be able to get around the bad hit markers)

You can kill all 9 daru on mayan tombs.
8 can be killed on Pyramid. 1 cannot.
Only 5 can be killed on Ice Temple, the other 4 cannot.
Only 5 can be killed on Mayan Jungle, the other 4 cannot
Only 5 can be killed on Mayan Temple, the other 4 cannot.
*(One of the kills on Mayan Temple is only doable using the devestator perk machine gun, so using only normal guns, only 4 kills are achievable)

Why cant you get all kills on other maps?
You cannot get the correct shot angle for some of the daru on other maps, they just will not register any hits from any angle.

Mayan tombs has a nice open map and it's pretty easy to run around, you can't really get lost.
After playing a lot of first rounds again and again, there is nearly always the last mummy getting stuck on one of the large vases on the right side of the map allowing you to casually run around killing all the daru's on the walls.
*You will see the mummies stuck behind the said large vase in my game clip, near the end, (3minutes 23 on video).
**If he doesn't get stuck, you can always entice him to get stuck, have him follow you, turn around and shine your torch on him to slow him down(Not to turn him yellow, just slow him down by blinding his vision) then run past said vase and run round the corner to the left quickly, he will most of the time follow and get stuck behind the vase, allowing you to casually kill the daru in peace.**
***If he doesn't get stuck behind the vase, run back past him and the vase and then 180 turn and try again, keep trying until he is stuck, sometimes it's annoying***
(Once he is stuck, do not approach him by walking down the stairs or come up behind him from the other side as he will unstuck himself and come after you)

My run through times started at about 6 minutes, then as i slowly started getting used to the map, like, where the ammo dropped, which route was quicker to run for example, i started to get some times as quick as 3-4 mins (My quickest was about 2 mins 40)
when you're running low on ammo, You're secretly hoping the ammo drops are perfectly placed right when you need it (A lot of luck involved)
Took me 4hrs 40 mins to get 505 daru kills.


Time Line for video
16 sec - Killing first daru
37/38 sec - killing second daru
1.12 - ammo drop location for two of the ammo drops
(Both ammo drops are in this area, only a few meters apart)
1.50 - killing third daru
2.06 - third ammo drop location
2.11 - killing fourth daru
2.35 - killing fifth daru
2.58 - Devestator perk activated
3.01 - Killing sixth daru
3.03 - killing seventh daru
3.11 - killing eighth daru
3.18 - killing ninth daru
3.23 - Vase where mummies get stuck behind. Always works
3.38 - showing you what happens if you come up behind them, they get unstuck
