You will have to help the knight protect his land from the many mean people who want to take it from him in Sentry Knight 2.
As the orcs, demons, or other attackers show up, you will use arrows or magic spells to kill them. To get through all the levels, you need to defend yourself against these attacks as much as possible. To aim and shoot, use the mouse. The 1–5 button keys will let you switch between spells.
To stay as far away from your enemies as possible, pick spells from the ice, fire, or evil tree. Use all of your spells and special attacks, and don't forget to improve your tower. Then you can go across three countries full of enemies like goblins and skeletons.
Have fun and good luck!
