About this game

Chthonian TD

is a fast-paced co-op blend of action roguelite and tower defense for 1–4 players.

Each run lasts 10–15 minutes. You fight off escalating enemy waves on the upper platform while farming resources in a crystal mine below. Spend from a shared wallet, build and upgrade towers on the fly, defeat the boss on Wave 7, and push your limits in Endless Mode, where enemies scale without end.

Action first, towers included

This is not idle tower defense.

You run, shoot, slam, revive teammates and reposition constantly while your defenses do the heavy lifting. Towers, traps and barricades shape the battlefield, but staying alive is always an active job.

Four classes, one shared economy

Each player fills a clear role:

  • Fighter – frontline control and clutch saves

  • Miner – fuels the economy from the mine below

  • Engineer – repairs, stabilizes lanes and boosts towers

  • Medic – heals, revives and keeps the team standing

All players share XP progression, but choose individual level-up perks, creating different builds every run.

Build smart, adapt fast

  • Crossbows for single targets

  • Cannons for crowd control

  • Traps & barricades to delay and redirect enemies

Structures use Crystal or Void resources, unlocking elemental effects, drops and synergies. Towers level up during the run, growing stronger without slowing the pace.

Enemies come in different categories, so mixing damage types and positioning matters.

What’s in Early Access

  • 1–4 player online co-op

  • Two map types: Dungeon (tight chokepoints) and Open (wide layouts)

  • Six waves + boss, with optional Endless Mode afterward

  • Shared-wallet economy with permanent meta progression

  • Stylized low-poly dark fantasy visuals

  • No friendly fire — teamwork over griefing

Balance is tuned primarily for 1–2 players; larger teams are supported and intentionally more chaotic.

Vision

Chthonian TD is a focused Early Access build centered on its core loop:
constant action, meaningful decisions, and replayable co-op runs.

If players enjoy it, the plan is to expand with more enemies, towers, maps and progression systems. For now, the goal is simple:

Fight above. Mine below. Survive together.

Chthonian TD
