The Council Apocalypse campaign came with lots of new bosses and spectacular attacks that were dragging down some systems' framerates. Many of these optimizations happen quite deep in the engine code so it has taken the QA team longer than usual to test.

GAME LOGIC IMPROVEMENTS 

- Parallelized collision detection code.
- Overall memory usage reduction.
- Code optimizations for some FX transformations (scaling and material swaps).
- Parallelized sphere hit detection code.
- Reduced the amount of hit colliders in some common objects (shields, parrots and airships).
- Created lighter versions for the enemy prop ships flying in the background on some missions. 

AI IMPROVEMENTS 

- Implemented smart time limits for decision makers.
- Parallelized task assignment code.
- Removed some redundant events in enemy animations.
- Implemented variable caching for the enemy horde manager. 

GAMEPLAY 

Along with the many tech changes, some new "under the hood" gameplay systems have been implemented. We now have more power to tune mission difficulty server-side. In this first iteration, our focus is on low MMR matches. Low MMR matches sometimes have a very slow pace, with too few enemies around. We are increasing enemy spawn rates and lowering AI skill a little bit to bring the game a bit more action and, hopefully, not modify the difficulty curve too much in the process. Veteran players will notice these changes mostly on mentor matches. 

- Increased enemy spawn rate at low difficulty levels.
- AI behaves more permissively at low difficulty levels.
- Decreased enemy damage at low difficulty levels. 

MISSIONS
