A causeway stands

Hollowgate

Creeps march the stone path toward the hollow gate. Place towers on the earth, spend gold from every kill, and hold twenty lives through ten waves.

• Choose Ballista, Mortar, or Rime Spire — each has its own range and cost.
• Select a tower to upgrade damage or fire rate, or sell it back.
• 1 / 2 / 3 to build · Space to call the next wave · Esc to pause.
