There will be different types of armor in the game (they are still in, but not used yet).
So there will be lets say 6 great classes of units:
- Fighters/Bombers
- Corvettes/Frigates
- Destroyers
- Battleships/superbattleships
- ODS
- Buildings
after the next update, there will be different damagevalues from one class to another one. For example:
Fighters will be good in hunting Battleships, but are weak against Buildings or Frigates/Corvetes.
Corvetes will own Fighters but if u fight with them against Destroyers, that will be a short fight

So the perfect player will have a fleet of nearly all classes or only the counterclasses of his enemy.
To prevent flaming: it will not make the big ships very weak against smaller ones... they are still very strong, but if one player only builds Battleships and the other one only fighters with the same metal, the one with the fighters should win.
I will put ig descriptions on all the units, so that u will know, for what this unit is used best.
