Playtest Now Live – Chthonian TD
For the next few days you can jump in and experience the core gameplay loop: fight enemy waves as a Rune Sprite while building defensive towers to survive increasingly difficult encounters.
The game blends action combat with tower defense mechanics and short roguelite runs. Each run offers card-based upgrades, resource gathering through mining, and different ways to scale your defenses.
An optional Endless Mode lets you push your build even further after the main encounter.
Feedback during the playtest is very welcome and helps shape the Early Access release.
