World 1
The Graveyard
Where the dead won't rest
A lonely isle at the edge of the kingdom, where an old crypt won't stay shut. Night after night, skeletons climb out of it and march the winding road to the crystal keep.
The crystal's light is all that holds the dark back. Should it fall, the dead would walk on, over the water and into the kingdom.
They don't come alone. A Monstrosity leads them, pitchfork in hand; a Necromancer raises the fallen; a Golem of bones pulls itself back together; and a Black Knight, once sworn to guard this keep, now marches against it.
Build along the road, hold the line and keep the crystal shining.
Siege
Thirty waves over three stages, saved at the start of every wave. Each stage ends in a boss wave and the next brings tougher enemies. Stage 2 also opens a fourth skill slot and lets towers and skills reach level 5.
- Casual
- Weaker foes, fewer elites
- Normal
- The intended challenge
- Extreme
