Almost all units have been redesigned and rebalanced.
A lot has been redone and a lot of new ones have been added.

Secret protocols have been completely rethought:
Allies have a choice of 4 destructive styles and rely much on them
The Empire chooses the path of progress and improves in it
The Union is free to receive powerful tools if it can "pay" for them

The production system has been significantly changed
now there are 4 common types:
ground
water
tactical support
experimental vehicles

The construction of the base has also changed:
Allies allies choose and combine from 3 directions.
bio laboratories, intelligence and technologies of the alliance countries.
The Empire is extremely dependent on energy and relies on large groups of repair robots for defense
The Union provides basic energy needs at the expense of Ore Refinery
and uses mobile Salvage Crane for expansion

Damage calculation is also updated
The table of damage multipliers can be seen in the main menu and (?) tooltip.

Ore mining was fully automated.
also, the mines are depleted faster,
but depleted mines work at half the normal efficiency.

Added 3 options for AI combining technologies of different fractions.
Changed the difficulty. Determines the size and quality of the army, not the economy.
