Patch 5.0 notes mention them and they are even showed on the anniversary trailer but i can't manage to find them, only thing i know is that they are supposed to be located on Triggers
- StarCraft II now supports formation movement, which can be turned on/off for each player via triggers.
- Unit can move and attack in a square formation with predefined separation distance between them.
- Currently, this formation movement won’t force all units in formation to maintain the same movement speed, which is different from the War3 version.
- Modders can tweak this data to customize the behavior.
The only thing i have found on Triggers so far are these two section about UnitPathabletoUnit/Point, i am pretty sure that's not what i am looking for but that's as far as i can go for now... Did anyone found the magical WC3 Formations location? If so i would love to know it aswell, thanks in advance for the eventual help
