In a multiplayer game very often you see at least 1 person taking huns. Huns are a hot favourite in 1v1 combat. While playing with Huns the only strategy that comes in mind is flush of which the 22 pop flush is most popular. They don’t have much of an advantage in the imperial age,so try to finish the game at the earliest preferably in feudal itself.Attacking variations in feudal age include two archery range +1 barrack flush, 1 archery range+ 1 stable +1 barrack flush. Of these I wish to point out one strategy in particular.Start with a scout rush so
that the opponent makes spearman. Meanwhile make archers to take his spearman by surprise.
Protecting your base is also important.One of the disadvantages of Huns is that they cannot make a house wall.So you need to either protect them with pallaside or with army buildings.
Knights are the most effective unit in castle age.For Huns they can be used in conjunction with the cavalry archers.So while advancing to castle age make 3 stables.If you have your feudal age army intact then I would advise upgrading them.In castle age try to raid as much as possible with cavalry archers and knights(keep them protected from pikemen).
