This mod is a total overhaul of the AI designed to smooth out the difficulty curve, providing more humanlike challenges that are both easier and harder than the vanilla AI. It features complete support for the Legion Expansion.

Please ensure that if you use this work you credit Quitch's Queller AI.

Want to make your own AI? I've written a guide to get you started.

RECOMMENDED DIFFICULTY

Below are recommendations for the difficulty you may wish to start on based on what you set the vanilla AI to or your ladder ranking.

When you need to increase the challenge, but don't want to increase the difficulty, give the AI an eco boost rather than adding more AIs. Not only will this be better for the sim, it'll stop the problem of there being less resources to go around for the AI which in turn makes it easier to beat.

| Vanilla    | Queller |
| ---------- | ------- |
| Normal     | Casual  |
| Hard       | Silver  |
| Relentless | Gold    |
| Absurd     | Gold    |

| League   | Placement | Difficulty | Eco |
| -------- | --------- | ---------- | --- |
| Bronze   | Low       | Bronze     | 1.0 |
| Bronze   | High      | Silver     | 1.0 |
| Silver   | Low       | Gold       | 1.0 |
| Silver   | Mid       | Platinum   | 1.0 |
| Silver   | High      | Uber       | 1.0 |
| Gold     | Low       | Uber       | 1.3 |
| Gold     | High      | Uber       | 1.5 |
| Platinum | Any       | Uber       | 1.7 |
| Uber     | Any       | Uber       | 2.0 |

SUBPERSONALITIES

By default, Queller at Uber level will adapt its play to try and suit the system and the opposition it faces. You can use subpersonalities to customise Queller's game to your liking, or help it play better where it's making poor strategy choices.

  • Aggressive
    • More willing to engage in battle
  • Air
    • Unrestricted air usage
  • Bot
    • Doesn't build vehicle factories
  • Free For All
    • More cautious about engaging in battle
    • Will get T2 as soon as it can afford it
  • Naval
    • Attempts to build a naval factory first
    • Unrestricted naval usage
  • Orbital
    • Will get orbital as soon as possible on multi-planet systems
  • Rush
    • Favours bots
    • Techs late
  • Tank
    • Doesn't build bot factories

MAP NOTES

The spawn the AI starts in and the profile used can make a big difference, even for symmetrical 1v1s. If you find the AI too easy on a map, try a different spawn point for it. And don't use Bedlam, the AI's forces can't pathfind on this map.

Be sure to follow the recommended number of players for any map.

I was recently made aware of an issue with the Queller AI and the Play From Here feature in Chronocam. This is a button that allows you to rewind the game to specific point in time and resume play. Unfortunately, for some reason this causes Queller to exhibit odd behaviours, such as failing to expand and failing to attack.

For the time being I would advise not using the Play From Here button in conjunction with the Queller AI.

The AI can only drop where spawns are available. If the AI isn't offered an offworld spawn, then it won't spawn offworld even if you tell it to.

Pls, make the ai comander capable of leaving a planet in those sistems were planets crush naturally pls, because now you can just leave the planet at the begining of a game and just wait and you will win.

Something strange happened to me in Styx sistem: an ai that was alone in the lava planet from the half of the match was very low developed, and wasn't even building orbital. It had nukes but didn't use them, and in a point tha ai just stopped expanding (just for info).

What difficulty? I believe v4.38.0 should fix this.

Just for info: in Demon's Den System, in the Little Friend planet the ai troops get stucked against a wall (there is a little entrance, but his troops don't use it).

In the late game the pathfinding system can get overwhelmed by the number of troops which can cause issues on systems with fiddling navigation.

Is not un the late gane, its at
the begining/mid game, the ai doesn't arrive to the late game, because I can atack him because his troops don't move from there, justo try to cross a mountain XD
