Special for its time.
Today, it is a hilarious story, that might pinch some nerves.
Pathfinding might have been good for its time, but while they get there, Units constantly block each other.
Economy is easy to do, its just 1 Resource, oil. Balance is more on Survivor side.
Evolved can basecreep to oil deposits easier, because they have 1 extra building.
However, that 1 extra building splits their building que into two, meaning you cannot tech up to make economy oiltankers, and have good combat units at the same time.
Unit statwise, consult the *enclosed instructionbook* (PDF)
Infantry wise, just like with vehicles, most units are the same for both sides, with minor stat differences.
Cannonfodder, besides specialists. Most vehicles, past the first 2, can drive over infantry, meaning only mass can safe them, and even then.
10 Survivor Infantry cost 500, and a Vehicles that can squish costs around 500 in Turn.
Vehicles wise, beasts from Evolved Faction work just like Vehicles.
From 250 cost Scouting Bikes and Scouting Wargriders, to Technicals and Bikes with Sidecar, the early stage has what a Mad Max fan would like to see.
Just as early, these are obsolete. Only big maps with little terrain blockage, allow these units to shine. With hit and run tactics. Any decent player however, would protect his tankers, since they won't need to take far away oil deposits in the so called early game anyway.
After that, drills that allow oil deposits to be used, and the first squish vehicles. An ATV for the Survivors, and a Giant Scorpion for the Evolved.
C&C is better.
