Question regarding the "open mind" achievement

[KaraKhitaï]

Hello fellow zombies slayers!

After a long break from the game i decided to try to get these new achievements and started with a shot at the "open mind" one. It says that you have to avoid building walls, gates or towers but does it mean no attack tower (like ballistas) or only the ones where you can put soldiers?

Since i was a bit confused i tried no towers at all, only troops and traps but i i died during the final horde :(

Its been changed many times since it came out so a ton of misinfo out there on it.

Most recently I seen is you can use bastiles, excu and shock towers with any troops or traps. But at some points bastiles, excu and shocks where not allowed so unless a mod comes in here and confirms it since it seams every patch one of these achivs get changed in some way that adds more missinfo I would avoid using them.

The best way to get the limited type achivs for no walls or no of any troop type is traps. Traps don't count adverse any of the achivs least so far. This allows you to mass them and just kite units over there all game. With enough traps + snipers behind you can do the no wall + only x unit achiv all in one run. Can do ranger + traps if you pref kiting. Sniper + trap is more dps or soilder + trap is more tankyness so they act as walls.

If going just for the no wall achiv thou jsut use rangers+traps as you fast tech to titans than mass them for a ez win. Titans not onyl act as walls they do massive dps.

Alright, thank you for your answer!

I will try again no walls no towers at all just to make sure i get the achievement. I know it's doable because i almost made it despite being rusty^^

If i didnt do a stupid mistake (i didnt notice a one tile opening on my western flank) i believe i could have held the final horde.

I just get the achievement today
I took a picture of my base in final wave

its just use Lucifer to burn fast the runners and snipers to kill the others before them get close to Lucifer, and if want can use Tharnatus to help Lucifer to clear,

So I used Titans to go across the map very fast and I got around 68 iron income to upgrade very fast the traps and build titans at same time
I got around 26000 gold in end, was with 5100+ income

Units Lost in total 12

Score Factor 100%

112 days win
population (challenge mode)

the trick:
you cant do that in
The Pearceful lowland either the The Desolated Wasteland
The end of map is too much open and
would not have enough time to fill the ends with your troopers
So the best way to do is in:
The Frozen Highlands

The map is way more closed, and have too much spots to you put them all together to burn all with AREA DAMAGE

PS: USED
33 Lucifer
15 Tharnatus
27 Titans
213 snipers
8 rangers
34 soldiers
732 traps (on iron upgrade)

Lost only 2 units

It's been a little while since i got this achievement but you can do this on any map without problem, i did it on the second one defending mainly with soldiers and snipers with a lot of traps on every opening. I remember i had like 4/5 lucifers in total for the narrowest chokes but to be honest they werent really needed.

Generally map 3 is the "best" map for achievements simply due to the better chokes and winding paths making it take longer for mobs to get to your giving more time to thin them down while lower noise sensitivity so you dont overpull as easy allowing for weaker balls of eg only rangers to work better. While map 3 gives a higher map % allowing for you to use one lower pop setting making the game all the easier.

It is possible on any map when its not bugging out thou more as a fyi for anyone that pops by.
