Factorio

Adds more powerful late and endgame combat capability to keep up with powerful enemies and huge biter bases.

A turret that can use any kind of ammo

Wave defense with infinite scaling and lots of settings. Tower defense! Available in freeplay mode and as scenario.

A laser defense turret viable for behemoth biters and spitters.

An early game water thrower that does minimal damage but slows down the enemies. You can use steam for extra damage.

Adds 8 (15 counting variations) new turrets for dealing with alien menace, as well as other military-related items. Good compliment to mods that add new biter types, like Rampant or Natural Evolution.

Humanity has made many great advances, but still looks to nature for inspiration. Thanks to users ThaPear, ratchetfreak, and Klonan for help on module healing. Thanks to fishycat for updating to 0.15. Thanks to ThaPear and TheBrain0110 for upgradable wall HP. Great work!

Adds a new roboport that automatically deploys combat robots.

Adds more turrets and shells.

Lightweight scripted shields with power consumption for all turrets (configurable or researchable)

This Mod change the turrets, vehicle and weapons ammunition system.

"Sniper and shotgun Turrets, Uranium shotgun ammo, a Sniper Gun, and more to come …" Sometimes, less is more! This mod adds options to "Combat by Samuel" that enable you to reduce range, damage modifier, maximum health, and resistances of sniper and shotgun turrets. This mod now includes the (updated) code from "Combat by Samuel" so you can continue playing with sniper turrets etc. in Factorio 0.18. I will revert this change once "Combat by Samuel" has been updated!

Provides cannon shells that pass through friendly forces.

Adds a second tier Flamethrower

Adds an advanced cannon turret.

Explodes when destroyed. NEW, you can change the damage now

Provides research to unlock a mid tier turret between basic gun turrets and lasers: Longer range and greater durability, but at the cost of much slower traverse speed and fire rate.

Adds barbed-wire, which can be placed down and hurts and slows down any enemy that walks on it. They can be upgraded to: Reinforced (more health and damage) Slowing (slows down more) Poison (deals extra damage) or any combination of the three.

Hardened pipes are expensive, and it requires some know-how to make them. However, they come with strong resistances and are ideal for use at the front-line. If biters or spitters always destroy the pipes that supply your flamethrower or water turrets, you should consider replacing them with hardened pipes!

Provides a rocket launcher with minimum range to reduce likelihood of accidentally nuking yourself!
