Notes

Most recent history will appear here, otherwise complete history available on github, this site has a 10,000 character limit.

0.16.26+ requires the experimental version of the game.

There will be a pause the first time and on every upgrade that Rampant loads.
This is due to indexing all the chunks that have been generated.

MP should be working
If experiencing desyncs, after an update, please do the following:

let me know
Load save with Rampant enabled
Save the map after Rampant has been updated
Load save in step 3

Configure Options not in game menu:

Ramp up to max biter wave size

Features

New Enemy Factions - Neutral, Acid, Fast, Physical, Electric, Inferno, Suicide, Fire, Nuclear, Laser, Troll, Wasp, Spawner
Swarming - Units will smoothly slide by one another allowing for streamlined attacking
Difficulty Scaling - A mod option to control how quickly the ai can perform actions like making attack waves.
Nocturnal Mode - A mod option to force biters to only attack at night. Does not yet affect vanilla attacks. Best use with daynight extender mod
Recycling Biters - When large groups of biters form on the game map and aren't assigned to a unit group or near a base will be periodically removed and refunded to the ai causing attack waves proportional to the number of units removed.
Breaching - When biters are destroying structures nearby unit groups will come to join them
Frenzy squads - When a unit group gets close to a player or start combat they switch to attacking everything in there path for a set radius or until there is nothing left
Rabid squads - Is in a permanent frenzied state as soon as the group is formed
Tactical Retreats - These will take place when a unit group is in a chunk that has reached a death threshold
Unit Group Forming - Any chunks with spawners in it that is covered by a pollution or player clouds will form groups based on the evolution factor
Probing Behavior Against Defenses - unit groups will attempt to avoid chunks that are soaked in death
Player Hunting - Unit groups will track the player based on there emitted pheromone cloud
Rallying Death Cry - When a unit is killed on a chunk that is past the retreat threshold, the unit will attempt to summon reinforcements to help them
Counterattacks - When the player is in combat near nests they will send reinforcements to unit groups
Reinforcements - Nests will send assistance to nearby nests under attack by the player
No Homing Projectiles - All projectiles are fired at locations and no longer track the player
Pathfinding - Unit groups will use potential fields to perform only single step pathfinding allowing for efficient and dynamic pathing
Peace mode - If something sets peace mode, Rampant will respect it
Ion Cannon Reaction - Firing the Ion Cannon will cause nests around the blast site to form into an attack wave and agitate all biters
Rocket Reaction - Firing the rocket from the rocket silo will cause the biters to form extra attack waves
Blockable Projectiles - Some of the biters projectiles can now be blocked by walls and trees
Raiding AI state - The AI will periodically send attack waves based on building proximity and not just pollution
Migration AI State - Where the ai looks for resources patches to setup new bases
Sieging AI state - Where the ai does a migration event but also builds towards the player and their base
Onslaught AI state - Where the ai gains 2x credits per logic cycle that can be used on units and buildings
Vanilla AI Replacement - The default expansion and attack waves can be completely turned off and allow Rampant to work its magic
