Elona Shooter tasks you with defending your castle from wave after wave of creatures. The Duck Hunt element comes in with the way you have to manually aim by guiding the crosshair over your targets with the mouse. It gets quite tricky with the swifter variety of creatures.
To help in the defence, you can upgrade your castle walls, recruit henchmen to increase your firepower and hire various workmen to repair the castle, or add bonuses to your experience or loot collected. You can also level up your character, bringing in new skills, and shop for a wealth of new weapons and modifications.
There's a Hardcore mode that autosaves to ensure you only ever get one chance, in true Roguelike style.
It all adds up to a surprisingly complex, rewarding and compulsive game.
