Wall & Turret Question

[JohnJohn]

Hello friends, i just have a question, i started playing Factorio recently and after some hours i was attack by "locals" fiercely, luckelly i was able to stop the attack before major damage was done, i just didn't see they attacking me, so...

But to my questions, i forgot to set defence but know i want to build walls and turrets around my factories, can i put the turrets inside the wall, or i need to put them outside so they can fire the locals? It's a silly question, but anyway. Thank you.

You can put inside wall , also with a good supply line to ammo delivery, you could automatically refill the turrets

Thank you, appreciate your help, i will set up the walls and turrets and if i can an ammo supply line.

I lost one of my Steam Engines, almost got out of power, never again, i will have my revenge.

I recommend fire turrets when you can get them and if you have enough oil.

Laser turrets is all you need :)

double thick wall with laser turrets two rows deep and nothing gets through.... nothing.

Remember to leave a 1-tile gap between walls & turrets, as the biters can chomp slighly further than a single tile. [Plus it gives you a nice player access route].

You need a wall if you're playing with biters enabled. If you're really mindful of pollution you can get away without building one for a long time but eventually the biters will encroach on your factory even if you're not polluting any nests and it will become easier to wall it off rather than keep clearing out new nests.

Nearly everyone will tell you your wall should be 2 tiles thick because big and behemoth biters can attack over a 1 tile wall and hit whatever is behind it. Beyond that it's really up to you.

Gun turrets have the best single-target damage and don't require electricity, but they're not very tanky, have a short range, and keeping them supplied is a major logistics operation.

Laser turrets are tanky, have long range, and only require electricity to operate. Their major downsides are their immense power draw (both when firing and in standby just from the sheer numbers of them) and poor damage scaling compared to gun turrets.

Flamethrower turrets have the longest range and are the only turrets that do AoE damage They're best at dealing with large, frequent waves. Their logistics requirements are similar to gun turrets. Their main downsides are that they generate pollution, have a minimum range and narrow firing cone, must be supported with gun and/or laser turrets, and can set your own stuff on fire if you don't place them smartly.

From what I've seen on the forums and such there's two main strategies to wall defense - a defense based on guns and flamethrowers (max DPS and no risk of a blackout/brownout if you are attacked at multiple points at once) or a defense based on laser turrets (easy to set up and maintain). They're not mutually exclusive of course.

Wow, i appreciate everyone's help, i was setting up my walls, i guess i will do another tile of wall and put one tile away my turrets.

There are some really great weapon and enemy mods out there that make the game way more interesting from a defense standpoint. Enemies that have special attacks, waaaay more HP, etc. Sniper turrets, rocket turrets, gatling guns, howitzers. Very cool!

[teravisor]

Sometimes best defense is offense.
Biters only attack when pollution cloud reaches them and attack power depends on amount of pollution that spawners absorb, so you can kill off all spawners close by to reduce their count (all non-concrete and non-stone tiles absorb little of pollution, also trees consume some of it, so far away spawners will produce less biters to attack).
Or you can go eco power and efficiency modules to drastically reduce amount of pollution(=biters) produced.

[JohnJohn]

So far no biters, i just rebuilt my walls (now 2 tiles thick) with turrets one tile away from the wall, i was just wondering how many turrets is enough, i guess i will find soon enough about that, again thanks for everyone's help.

[Killcreek2]

"How many turrets" is a tricky question: it depends on which turret types you are using, ammo type, biter evolution levels, your level of military research, & also the terrain to some extent.
Here are my general benchmarks:

Early game: a line of gun turrets with AP ammo, spaced out so their range marker overlaps with the next turret [so each can cover its neighbours].
Mid game [evo 0.4-0.7]: double up the guns / use a solid line of lasers / mix a few flamers in. Add a double-thick wall. [Varies a lot depending on location / terrain / resupply points].
Late game [evo 0.8+]: usually double wall, solid line of lasers, with 4 guns & 1 flamer per every 10-12 lasers. Or double lasers & a thick wall. Or flamers & dragons teeth. Lots of options at this point.

Just have a play with a few different turret / wall layouts & you will soon find a setup that suits you.

If you want to "field test" the designs, go round up a large-as-you-dare pack of biters & spitters, then lead them directly at your wall ... For Science![i.imgur.com]

Some advanced players clear out all biter nests within their pollution cloud, and THEN build a defensive wall OUSIDE their pollution cloud. Like, really really far away from their base. That way the biters never expand into the cloud, and never send units to attack.

This requires a lot of planning and resources, but is an extremely effective long-term strategy. Biters primarily evolve through absorbing pollution and having their bases destroyed, and after you get the wall set up, those two influences stop.

I use blocks of 16 laser turrets without walls. Fully upgraded everything dies.
