This is a real time strategy game. You are sending an army and supporting by archery. There are 5 stages, each stage has different 3 mode so that means there are 15 stages you can finish. Your kingdom is attacked so you have to defend it, but you also have to fight back. Maybe you could send your army in all lanes and get the victory or you defend early with towers to deposit your gold and fight back when it is enough. Something like that.
