Chthonian TD
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

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.

Co-op action roguelite × tower defense. Run and shoot as 1–4 players swap between combat and mining layers, build towers, survive 7 waves including a boss, then push into Endless - unlock permanent stat upgrades with crystals.
