Want some tips on how to design good campaigns with satisfying battles? I wrote an article about doing just that[sinisterdesign.net] for the original Telepath Tactics, and most of my advice from back then still applies!

(One big thing that's different in TTL: you don't need to use OnCharAttacked triggers to remove Passive status from enemy units anymore! You can just assign group of enemies to an AggroGroup, slap Pursue tags on them, and everyone in the group will lose their Passive status the moment they attack or are attacked.)
