First of all, a massive thanks to Mitch for the awesome feedback! We immediately got to work on those last details you mentioned and took care of all of them in this update. Here is what's new:
Mortar Buffed: You were right Mitch, it was a bit underwhelming. Instead of just buffing its raw damage, we increased its hit count and AoE size so it truly makes an impact on the battlefield. It's much more viable now!
Contract Trophy Fix: Fixed a bug where fully completed contracts would still continue to give out trophies.
Decrypt 5 Achievement: Fixed an issue where this achievement wouldn't pop even if the conditions were met.
Tactical Formations: Zombies won't just spawn randomly anymore. Depending on their type, they will now attack in much more organized ways using over 10 different military formations like Shield Walls, Pincer Movements, and more.
Performance & Bug Fixes:
The issue where hundreds of Damage Texts caused FPS drops has been completely resolved with a brand new code architecture. Performance is now buttery smooth, no matter how many numbers are flying around on the screen.
Fixed a bug where Bear and Riot zombie levels wouldn't properly reset after doing a Hard Reset on the save file.
Fixed the bug where enemies moving out of the Leader Zombie's range would keep their speed buff forever. Also fixed Force Shield zombies granting armor to unarmored units (Phantom Armor issue).
