I am designing a medieval themed RTS game and want a unit that performs better than a regular unit would when outnumbered or against better units making them slightly resistant to good enemy tactics.
I am planning on having a attack bonus if your soldiers have outflanked the enemy and a simple armour mechanic. But most of the tactics to be simply that a larger force will take fewer losses to a smaller one.
I am not committed to any combat mechanic so answers can suggest any idea.
So far I have only been able to imagine: extra armour against units they are not targeting, if outnumbered the additional soldiers can do less damage. poison, they will lose the fight but the enemy will lose more health overall. Immune to outflanking.
