You do not have to turn on every feature. Here is a "Balanced Trainer" loadout for Build 091 that reduces grind but keeps tension: You do not have to turn on every feature
Before diving into the specifics of the Build 091 trainer, let’s define the tool. Unlike a mod (which changes game assets) or a cheat code (which is hardcoded by developers), a trainer is a third-party executable that runs alongside your game. It scans your system’s RAM for specific values (like your mercenary’s health or money) and allows you to lock or alter them in real-time.
For Jagged Alliance: Back in Action, a trainer is not about "losing." It is about scenario manipulation. Perhaps you want to test a late-game weapon mod without grinding for 10 hours. Maybe you want to simulate a "god-like" mercenary platoon. Or, you just hit a difficulty spike on the treacherous island of Metavira and need a quick health boost.
