Galactic War Difficulty and Adding More Maps


Galactic War. Galactic War never changes. Except for when it does! Galactic War is a roguelite campaign for Planetary Annihilation, starting with only a small amount of tech, you battle your away across the galaxy to uncover more, fighting increasingly tough and numerous opponents until you defeat the three enemy factions. Defeat bosses in certain systems and you’ll unlock new starting loadouts which you can use in new campaigns.

This guide will help you pick the right difficulty, explain the factions and unlocks, and also guide you through adding more maps.


The higher you set the AI difficulty the greater its eco modifier, economy handling and general intelligence will be. Normal uses a different set of maps from the other difficulty levels, with far less multi-planet systems.

By choosing a colour in the lobby you are choosing a faction. The faction you select will not appear in your war. The only difference between the factions are their boss systems, so choose a faction whose boss you wish to avoid.


Your starting loadout determines what units you have access to from the start of the war. You start with one loadout unlocked: the Vehicle Commander. Seven loadouts remain locked. You will unlock them by defeating particular faction bosses.

Each faction has multiple possible bosses. At the start of a war one boss is selected for each faction. You may not always encounter a boss tied to a locked loadout.

Adding More Maps

Once you’ve played a lot of Galactic War you will have seen all the built-in systems more than once. You might fancy a change, have particular systems you’d like to see, or just want more multi-planet than you get out-of-the-box. To achieve this we will use Shared Systems for Galactic War, a mod which lets you load in TITANS systems, your systems, and systems out of any map pack you lay your hands on.


Go into Community Mods from the main menu. Click the Available tab and search for “gw”. Select Shared Systems for Galactic War and choose to install it.

Using the Mod

When you go into Galactic War you’ll notice something different.

Galactic War with Shared Systems for Galactic War mod installed

In bottom left you now choose what systems to load into Galactic War. By default it has selected the Uber category, which are the 26 skirmish and multiplayer systems that ship with TITANS. Below that is My Systems, which would load any systems you have created or imported. Default Systems and onwards are categories on the Shared Systems server. These are areas which anyone can upload to (default systems) or are restricted to specific individuals (everything else). I recommend against using these categories for two reasons:

  1. Many of the systems are old and out-of-date
  2. The Shared Systems server is often offline, or when online is slow to load the systems
Loading systems from the cloud

In the screenshot above we see a 0 next to Default Systems and the go to war button is greyed out. This is because the systems from Default Systems have not completed loading. Given the count of 0 I would assume the server is offline, but even if it were online you wouldn’t be able to play until hundreds of random systems had been loaded.

So how do we add more systems? Simple. Map packs.

Adding Map Packs

Return to Community Mods on the main menu and this time search for “map”. Select the ones you want and click install for each.

Checking the Contents

If you haven’t used these map packs before you might want to check out what you just installed. The easiest way to do this is to go into the System Editor from the main menu.

Viewing installed systems

Each map pack consists of one or more categories which are displayed as tabs. In addition you will see My Systems, which are ones you’ve created or imported, and Uber, which are the systems that come with the game. Shared should be ignored.

If you want to get an idea of what you’ve added just browse through the select here and click on a system to get an overview. You’ll be able to see number of planets, number of starting locations, planet size, etc. You can always load them in the editor if you want to go in-depth, but this overview should give you an idea of which categories you want to add into your war.

Adding Your Maps to Galactic War

Now everything is loaded all you have to do is pick which ones to use. On the Galactic War screen you’ll see that it’s not a list of map packs, rather it’s a list of the categories you saw in System Editor.

Loading map packs in Galactic War

Each category displays a system count, in addition once you select a category the number of multi-planet systems in that category will appear in brackets.

You are free to mix and match the system categories as you wish to get whatever Galactic War experience you want. The important thing is that you should now have a wide variety of exciting systems to play on.
