Overhead mountain tiles....ok all the opinions get me confused

[Wish Granter]

Sooooooooooooooooo, people tell that you NEED 15 Dark green tiles for infestations to spawn, other say you dont, others say you do, others say only if you piss in bottles you even can get infestations.

So anyone in here that KNOWS how it works, and does NOT guess how it works, just 3 short questions for 1.3 as I have gotten infestations with only 2-3 dark green tiles.

1. Do you need 15 Overhead moutain tiles DIRECTLY NEXT TO EACH other for infestations to spawn, or is is enough if there are 15 " " tiles in your base in a , lets say, 50x50 radius.
2. if there is not a single overhead mountain tile ANYWHERE next or near my base, and I only dig up about 8 of dark green tiles, no infestations will spawn, or will they?
3. Does the -17 Degree thing still work? That would make me shift my freezer to that spot as I have not much space on my tropical Island and I got 100 mods that want to fit on my map too.

Maybe a tad outdated. It may have changed a little over the course but i found this guide quite helpful.

Ill take a look at it and check if its quite to date I fear its not. But thanks! Ill watch it.

Infestation can spawn with one overhead mountain tile on the map. It has nothing to do with the proximity to your base.

Freezing works but is not viable. The best way to deal with bugs is to give them another more comfy place to spawn in. So dig out a room away from your base and build a fire trap that can deal with the bugs.

There is actually an overlay in dev mode that shows you the exact probabilities for an infestation on your map.

uhh that dev option sounds interesting I have no problem using dev mod on Ironmen if necessary or for information.
Can you give me a short hickup on what option that is.
There 2 two "circles" on the toolbar up there, what circle should I press and what option should I then search in the window?

ONE tile on the map is enough? Damn see I thought its at least 10-15. For a VANILLA infestation to spawn.
Yeah the freezer thing has the problem since its s TROPICAL Island that one heat wave is enough and (knowing randy on hardcore or merciless), the second it will fall over -17 Degree im gonne get a infestation XD.

But as long as I can hold it at -17 its all fine. If it falls over -17 I guess I have to run in and wall off my freezer ;D

F.e during EMP mission.

You activate dev mode -> open inspector (magnifying glass) -> visibility -> draw infestation chance

As far as I know it has never been that way.

That is simply not feasible. The amount of ressources for coolers and electricity is much too high for the benefit. Workspeed of pawns decreases and they will always "sleep in the cold" if you freeze it. Makes absolutely no sense.

Just light everything up, smooth or build floors. Then dig out somewhere else on the map so bugs spawn there.

Nah im not building in the mountains XD. I have given up on that long ago, since raiders just dig easly trough 30% of the whole map to get trough you, making mountains 100% useless other then for stone.

The freezer and power is no problem with 100+ mods and rimatomics later. Its just that one EMP is enough to make it possible to spawn ♥♥♥♥.
Ill try the debug options thanks!

(I currently play on tropic Island, so there are only a few spots on with Green tiles, and I can then use those for freezers or cooling chambers for the weapons and PCMS.

One mountain tile is enough for the game to see a bug-spawn event is viable. Though, bugs can't spawn inside rock/obstructions, so there needs to be space for them around that tile to spawn as well. That space does not have to be a mountain tile. ie: The engine sees one suitable mountain tile, determines a bug spawn is warranted, spawns bugs within a radius of that mountain tile whether or not those tiles are also mountain tiles. This is how you can get bug-spawn events "outside" after mining the outside edge of a mountain or spawns in supposedly undesirable rooms inside a base.

2. if there is not a single overhead mountain tile ANYWHERE next or near my base, and I only dig up about 8 of dark green tiles, no infestations will spawn, or will they?

I don't know what a "dark green tile" is. However, if there is no suitable open mountain tiles within range of your home zone, no bugs will spawn.

Note: (Clarifying) Overhead Mountain Tiles are "Heavy Roof" tiles. There are also "Light Roof" mountain tiles. Only Heavy Roof Mountain tiles matter for the bug event roof type. The Roof type can be seen in the lower left-hand mouse-hover description box.

3. Does the -17 Degree thing still work? That would make me shift my freezer to that spot as I have not much space on my tropical Island and I got 100 mods that want to fit on my map too.

Temperature control to prevent bug-spawn is not reliable. It can work, but it working relies on an unstable game mechanic. Temperature control is something the player has to constantly juggle as part of the game, so it's going to eventually fail and require you to act. (All sorts of power/electronics events as well as breakdowns - You do not want a pawn running out to fix that cooler. It can work, but when it doesn't is what you're really concerned about. :))

As 123 pointed out, your best bet is to prepare an area that is very likely to host a bug spawn event. There is no fool-proof method here as there's a small bit of RNG when there are multiple suitable locations. But, you can very nearly guarantee that if you do get a bug spawn event, it will occur in the place that you prepared. Prepare that area to contain a decent sized spawn, dump a bunch of chairs in there and maybe a few piles of wood, make a controlled entrance, get ready to chuck Molotavs and close the door. (An airlock can help protect the molotav hucker as they retreat.)

these two screenshots get me confused with that "1 Tile is enough therorie".
The blue tiles are (and thats not a guess, that what debug mode says is viable) viable spawn places everything else it not.
When building deeper in mountains then it gets viable, but with only a few "dark green tiles" (or Heavy roofing) there is no viable spawn option following the game.

So if one tile is enough I dont understand why debug mode tells me that there is no viable option to spawn.
Correct me if you only meant that QUEST Infestations can spawn on 1 tile.

Or the debug options lies to me, because the 10 tile in my freezer are no viable spawn neither, even if oer -8 degree, after which point it doesnt matter.

The blue tiles in the debug mode show the likeliness of bugs spawning in that specific area. Things can be a valid infestation spawn point but not show up in noticeable blue because there is a much better spawn location somewhere else on the map. From what I have seen they heavily prefer to spawn "inside" these days, so that small enclosed area is a darker blue while those exposed caves are probably normally valid but essentially a 0% chance currently because of the better spawn location. If you were to fill in those dark blue tiles with walls then you would likely see other tiles turn blue. Things like light level also adjust the chances, and I think temperature does as well so while -8C wont prevent a spawn it will reduce the chances in a specific room if there are other valid locations on the map.

I just use the better infestations mod and switch off infestations. Illogical problem gone.


If you want a good infestation strategy. Find a corner of the map you dont care about. Then carve out a good 10x10 room. Place a chair/bed in there. It will be the most likely place an infestation will appear. Be sure to set it up properly with considerations of insects swarming the map. Smoothed/tiled rock is slightly less likely to have an infestation occur. Though the risk does not ever go away. Leaving rough flooring after mining has the highest chance and the furniture (mainly beds) tricks the game into believing that area is your base. A lot of the attacking events are directed towards beds for the ai.

yeah I know about the strategies, but I rather dont have them at all, they are just annoying. So I search for perfect knowlegde about theire spawning chances to see how much I can do with what less I have space on the islands

Interesting thanks I dig deeper down a bit with tests. Right now I just try to use as much as I possible can to get most space out of the island. I love the idea of that challange, being on single islands and having to build brigdes, having to use best what I have as space

Download better infestations and turn off the spawn then. Problem gone

turning off a challange doesnt work with my Ego XD
