Aggressive Crisis Engine 3.7-3.10

Legacy version for Stellaris 3.10, 3.9, 3.8 and 3.7 (but should work on 3.6, 3.5, 3.4 and 3.3 too). Current version here: https://steamproxy.net/sharedfiles/filedetails/?id=2268189539
Documentation for modders is included in main mod folder.

NOTE for users playing on older game patches:

If you are running pre 3.3 ACE (ie. 3.2 and not this one) with Merger of Rules but without Gigastructures simply delete \common\scripted_triggers\!!!_acemod_sfex_debug_scripted_triggers.txt in the ACE workshop folder or use Irony to prioritise Merger. This fixes unusable jump drive.

Aggressive Crisis Engine (ACE, ACEMOD) is a collaborative Stellaris mod with new crisis AI and a great amount of crisis improvements.

Vanilla AI is off for main crises and all fleet movements are mod scripted, this includes military fleets, constructors, army transports, swarm infestors and colossi.

Dimensional Anchors are visible on galactic map.

- Full support for Contingency, Prethoryn Scourge, Unbidden, Aberrant and Vehement. Optional for Gray Tempest, Katzenartig Imperium (Gigastructural Engineering), Overgrowth (Fatal Foundations Story Pack) and other custom crises.
- New custom pathfinding accounting for wormholes and gateways
- Fleets are relentless and always seek targets.
- Defensive fleet recall for Contingency worlds (optional).
- Crisis Manager (optional).
- Galactic empires receive initial massive damage penalty against crisis factions so new technologies need to be obtained in order to mitigate this (optional).
- Crisis colossi (optional).
- Dynamic Mod Menu support with menu access permission management for multiplayer.
- Various fixes related to crises.
List of features is subject to change.

The mod is load order independent as it uses LIOS/FIOS overwrite methods where needed, but preferably at the bottom. Aggressive Crisis Engine overwrites very little but what is does is crucial for it to work.

ACEMOD configuration menu opens on game start. In order to access menu after start of the game you can use one or more of the following mods:
- Dynamic Mod Menu (3.0.*) by Erdnuss (SLEX).
- Mod Menu by had.
- Dynamic Mod Menu by mario0244.
- Infinite Stellaris Framework by 小傘INFINI7E.
You can also fire mod menu with an event acemod_menu.1 console command.

ACEMOD is flexible and modular. Users are able to switch individual components on and off on game start.

Modders can use ACEMOD AI for their own custom country_types and exclude individual fleets from ACEMOD AI for their own events. Current list of effects for modders to use is inside acemod_fleet_events.txt. See AI framework documentation (modders) for details.





This mod is highly compatible but requires disabling vanilla crisis AI. For this reason make sure ACEMOD overwrites any mods which change crises (this includes Starnet AI and Glavius AI).

See AI framework documentation (modders) if you want to get technical.



Overnight test run of ACEMOD AI crisis on Stellaris 2.7.2. Default settings but technology cost on x0.25. All empires were on repeatables. Crisis on x1 strength was squashed, this is a x5 Scourge.

When merging mods for personal use by Irony Mod Manager[bcssov.github.io], WinMerge[winmerge.org] or some other way, please make sure ai = { } block has enabled = no. Otherwise ACEMOD AI will be overwritten by vanilla AI and won't work properly. For list of overwrites see AI framework documentation (modders).

Fiiral, OldEnt and Rodahtnov hope you will enjoy this mod.

Thank you to 150 players who decided to try the mod in beta stage.
