3rd Invasion - Zombies vs. Steel

In this game Strategy is the key to Survival.
You need a awesome Grand Strategy to win this war,
A RTS action game with an Cool Base Building feature.

Build your base to helping you to fight a war against Armies of Zombies, Aliens and a Plant-based intelligence.
Normal RTS like CNC, you just need a simple Strategy, but this game has another layer to it,
You need to make plans for a Grand Strategy, setting this Single player RTS apart.

You might win one battle, but the enemies can attack another spot, just like in a real war of Survival.
-
These are the units under your command.

Use Base Building to protect your army, as you plan your next raid into the enemy area.
When the fighting begins, and your army rolls into Action, You alone have the Strategy to win.

The Enemies:
Zombies just attack, with no real Strategy. Their Base Building is simple, with little defenses.
The Plants, also lacks any Strategy, but they are good at Base Building, and hard to kill.
The Aliens have a Grand Strategy, and advanced base building, with strong Defenses..

The map:
This RTS war game, has 30 maps; Some give you new weapons, others more money.
The wrong Strategy will get you fighting in some lost desert, will the Zombies and Aliens kill of the large cities... draining you for money.

This game was build looking at Command and Conquer.
But where CnC is build on straight forward battle, where if you win one battle, you get to the next stage.
This is more like real world strategy, where one battle won, might mean the enemy got in behind your forces, and took a high value land from you.
Think Risk, but with CNC battle's.
