Agressive Multiplaying
In case you want to win a game and are sure the other player will not stop playing you, if you win fast consider this:
In pretty much all multiplayer strategy games attacking as fast as possible is the easiest way to win. This is especially true in KaM, as 1 militia can end other players game if he doesnt have any units. Thats of course not overly fun thing to do, so be reasonable. But bumping out milita as soon as possible is usually a good thing to do, because the opponent might be doing this aswell, and you need your units or towers.
* in order to flee with your melee troups, make the opponent your ally for a moment. This way your troops can run away from melee fights or right through the opponents town. Otherwise the units would get stuck with hand-to-hand fighting.
