As with all things Iron Harvest, Operation Eagle will take you on an expansive story arc where morality is neither black or white. Will Usonia be conquer or oppressor?

Info: Changelog 22

Thanks to players feedback, we’ve implemented a ton of changes to improve the game experience when playing against A.I.

  • We’ve reworked how the A.I. chooses which units are most effective for the current task or for destroying certain units
  • The A.I. is more responsive when they detect hostile forces and groups start building combat strategies immediately
  • We’ve revamped the A.I. at all difficulty levels to make them more distinct from each other. In particularly, Easy and Insane are affected the most, with Easy no longer idling for extended durations, while Insane will put up much more of a fight throughout the entire duration of a match
  • We’ve tweaked A.I. at all difficulties to use unit abilities where available and applicable
  • The A.I. now features an improved decision making in combat situations, resulting in better strategies when to push or to retreat
  • Unit A.I. is now prevented from relentlessly chasing retreating enemy units. They will break off pursuit after a brief period if they can't kill their target
  • Increased the chance that the A.I. will use small unit groups to quickly conquer objectives
  • A.I. now deals with barbwire more intelligently, either cutting or navigating around it
  • Reduced the chances that A.I. will all-in rush your base at the start of the game

As a result of all these improvements we’ve had to adjust the main campaign maps to restore their original spirit. This increased the general campaign difficulty which we then reduced again through other means while still keeping the smarter A.I. and enemy behaviours. Therefore, many old campaign maps are now more responsive, dynamic and fun than ever before!


General Changes:

  • Fixed a bug so that Gunter can no longer target allies, and himself, with his punch ability
  • Fixed an exploit that allowed building multiple HQs in team games
  • Tons of smaller fixes and improvements

These changes and improvements regrettably, but unavoidably, mean that in-mission saved games files from before this update are invalidated. We apologize for this inconvience but campaign progression is unaffected.


Balance Changes:

For skirmish/multiplayer, Usonia changes everything. Everyone will be experimenting with them to figure out what works best. As the chaos on the battlefield unfolds, we will be monitoring the game closely, collecting game data and making assessments. It will require time for the dust to settle, but no doubt we will have to modify the games balance once an accurate picture emerges.
