Your mission in Soulkeep is simple in its title but it is hard in its work as you have to defend the gate against fiends and those fiends are huge in numbers and to start your mission as a beginner in soulkeep, you have to know somethings about the gate and about the hearts and also waves.
I will consider this as beginners guide and if you get benefit from it so you could comment and I will continue with this series as some need a simple explanation about what they would play and I have found that it is not about towers and spells but you have to know somethings about the map and how things work in this game.
As I remember in level 2 while I was defending the way very will and kept my hearts safe I have a new surprise when I have found that fiends are coming from a dead tree behind my towers and went to the gate and its was a surprise that costs me my hearts in this battle and I replay the whole battle for this mistake.
First you have a specific number of hearts you have to keep them from the beginning of the battle till the end otherwise you would be defeated and this is the allowed number of fiends to enter the gate which is a magic gate to your world and you are defending against those fierce fiends.
Second thing to keep in mind is the map and the ways that fiends came from and you have to keep ways safe as the distance that friends will walk to your gate is the available time to attack them and get them down so you have to follow the arrows that appears before the way to see what they would go.
