Base Defense Guide

Abiotic Factor is a survival crafting experience, and survival only gets easier if you have a safe place to call 'home'. Throughout your playthrough, you will find many things that want you dead and your things gone. Whether you lead a monster back to your bed (or sofa, we don't discriminate) or you happen to be experiencing a Portal Storm. This section will help you set up a defense to keep those nasty baddies at bay!

Several portal worlds (especially The World in the Mirror and the third floor of the Furniture Store) appear to be designed as safe base locations that do not need defense. Many portal worlds do not spawn enemies that will attack bases, and bases in these worlds are just as easy to reach as bases in the normal facilities if you use the Personal Teleporter.

Enemies can only attack your base if the player is nearby: if the player were to spend the night very far away from the base (ideally in a portal world), it would prevent sieges. Ideally, you want all players to be far enough away that they have passed a loading sequence, indicating the base has been unloaded and, therefore, cannot spawn enemies.

Portal Storms

First, no matter how good your perimeter defense might be, it won't do you any good if your enemies appear within the perimeter! You can find out more about Portal Storms here. To defend the core of your base, you will need to upgrade your Crafting Bench, specifically with the "PORTAL SUPPRESSION FIELD" upgrade.

Barricades

Makeshift Barricades in game

Barricades are the most rudimentary form of base defense, keeping hostile entities from entering it in the first place. The most basic form of barricade is any furniture you can find. Make sure you have a Screwdriver or equivalent and start packaging desks, fridges, or anything sturdy enough!

However, basic furniture won't last you long, and this is where the crafting part of "survival crafting" comes in. Below is a table of craftable barricades, which are sturdier and have additional uses, such as ramps and shelves leading you to out-of-reach areas!

Traps

So, keeping baddies out is all well and good, but your barricades won't last forever, and eventually, the enemies will break through. That's where traps come in! While they're trying to figure out a way to get in, traps will damage and hopefully kill any intruders before they can do too much damage. A clever scientist can easily use traps offensively, just as well as defensively! Some require power, some reloading, but they're all quite deadly.
Below is a table of craftable traps.
