File Description

This is an updated version of the oustanding mod for skirmish AIs in supreme commander,

It includes 6 selectable ais. All are hard, 3 normal ones plus their cheating versions. Personally I love the Sorian Rush AI on land maps, you get constantly harassed by a varying stream of units that probe your defences looking for weak points. The Jaws AI is a must for any water map. As I'm sure you've found, the in-game ais aren't great at water maps.

One really cool feature is the chat. If your allied with one of the ais, they will send you messages letting you know, who they're concentrating their fire on, so you can help them in a big push.

Check out all the new additions in the readme below

If like me, you want more of a challenge from an offline skirmish give it a go. You won't be dissapointed!

Sorian/Jaws2002 AI Pack version 2.5f

This file includes 6 AIs; The default Sorian AI (Kind of like the balanced), Sorian-rush AI, and Jaws2002-water AI. You can either choose an AI or choose the "SJ Chooser" to have it choose the best Sorian/Jaws AI for the map.

The other 3 Ais are cheater versions of the default, rush, and water AIs.

This AI uses a lot of custom behaviors to make the AI play smarter, play as a better ally with both humans and AIs, and communicate with its allies.

This version will only affect the behavior of AIs in our AI pack.

See this post for more information.

How to install

Simply place 01_sorian_ai.scd into your THQ\Gas Powered Games\Supreme Commander\gamedata folder. When you start your next game the new Ai's will be available from the dropdown list. You do not have to choose this mod from the in-game mod menu, it will be active automatically.

How to uninstall

Simply remove the 01_sorian_ai.scd from your THQ\Gas Powered Games\Supreme Commander\gamedata folder.

Known Bugs

Because of the way this mod is installed you cannot have more than one AI mod installed at once. If you want to use more than one AI (such as this one and Thirlad's AIs) you will have to merge the AI packages. See the following post for information on how to do that.

The AI does not like the 250 unit cap limit, it seems to get stuck.

The AI will not work on custom maps that do not have the appropriate map markers. See Aralez's post about map markers for more info:

Some maps have quirks. There was a map guide at one point, but because of the changes in 1.6 I have removed it for now. Hopefully the changes will help alleviate some of the map problems.

Units will still get stuck along walls. It seems to have a real problem with semi-circles.

Naval units still get stuck at times, especially if there are a lot of them.

The AI does not like it when the civilians on the map are hostile.


Q. While playing a game other people cannot hear my chat messages.
A. If you have the AI installed (even if it isn't being used) and others in your game do not have it installed it can cause communication issues. Either; a)make sure all players have the AI installed, or b)move the AI mod's .scd file out of the /gamedata directory, or c)change the AI mod's file extension to something like .bak or .dontuse.

Q. Why wont any of the AI commanders move?
A. Make sure you are running the most up to date version of SC. As of this readme the newest version is 3254.

Q. Why doesn't your AI show up in the Mods menu?
A. This mod wont show up in the mods menu. After following the install instructions the AIs will show up in the dropdown menu

Q. Why wont your AI show up in the dropdown menu?
A. Make sure you do not have any other mods installed. Some other mods can conflict with this mod, especially other AIs.

Q. Is your AI really any harder than the default AIs?
A. I think so, and so do many other users. You would really have to see for yourself. If you see some room for improvement please feel free to leave feedback here:

Q. After installing your mod all of my replays desynch, why?
A. Desynchs will occur if you watch a replay that was recorded with any of the following: 1) A different version of SC. 2) With any mod that you do not have installed. 3) With a different version of a mod than you have installed.

Q. I wish your AI would <insert nifty idea here>.
A. If you have a neat idea for the AI, even if you don't think it can be done, please post a reply letting us know. Many of the ideas that make this AI great came from user replies. If it is a good idea and it can be done, we will do our best to implement it.

Q. How do I know what version of the AI I have installed.
A. Starting with version 1.4 or 1.5 (can't recall) the version number will show up in-game next to the AI's name. It will also be in the drop-down menu in the game lobby.

Q. How do I modify how much the AI cheats?
A. In each cheating AI there is a function called AIResourceCheat. In that function you will find 2 lines that contain '* 15'. Change the 15 to whatever you want the resource multiplier to be.

Q. Which AI do I use for what map?
A. Here is a breakdown:
Sorian AI (or C version): Mostly for 20x20 or larger with a land bridge if the map has water.

Sorian Rush AI (or C version): 10x10 or smaller with a land bridge if the map has water. Does well without a land bridge if Aeon.

Jaws2002 Water AI (or C version): Any water map with no land bridges.
