Intensified importance of hills in defense. Some positions like Cemetery Hill and Culp's hill will feel like fortresses now.

Better visual representation of pseudo 3D terrain. You will be able to perceive hill obstructions more accurately as unit formation bend and scale on terrain.

AI overhaul. AI should attack and defend much more efficiently with all personalities.

Some scene fixes including big error in "What if Buford had not held McPherson ridge" which resulted in a broken scenario.

Various fixes and balances for MP battles that were unbalanced.
- CSA in "Pickett's charge" has now also Pettigrew and 3 other brigades at their disposal making things really challenging for the Union which get a few more artillery for compensation.
- In "Union on the Offensive", CSA have 2 more brigades, and Union has less artillery.

- In "Devil's Den" reinforcement times for Union have been balanced.

Altered the arrival time of 1st day/1st battle units to fit more the historical facts.

Fixed occasional super damage bug when units were in melee that destabilised combat balance.

Fixed many overpowered artillery batteries for both sides.

Fixed several bugs that made AI to fight at disadvantage since almost always its altitude parameters were lower than the player's and there were also other multiple issues. Now the AI will fight to its full potential, as never seen before.

This update has been shaped up thanks to the valuable feedback of many volunteer testers. We would like to honor the most active and helpful during this test phase by mentioning them below:

OLee O'Hara (Demanding General who took detailed notes of AI failures that helped to make it better)
JamesL (Veteran General who was only getting pleased when the AI was able to inflict more casualties than him)
YueJin (Methodical General who always gives unquestionable advices for a better gameplay)
