About this game
Chthonian TD A co-op action roguelite x tower defense game for 1–4 players . Defend against escalating waves. Descend into a crystal mine to grow stronger. Face a powerful enemy that shifts the pace of the run. If you survive - push into optional Endless Mode . Short runs. Constant pressure. No autopilot. You’re Always in the Fight Not a passive tower defense. Expect to stay active and make decisions under pressure from the start. You move, aim, dodge, revive teammates and react under pressure while your defenses buy you time. Towers strengthen your defense - player decisions still drive the run. Every Run Evolves Level-ups offer upgrade cards that reshape your build. Some make you safer. Some reward greed. Some push the run toward instability. Your build changes how the game feels. No two runs play the same. Power Has a Price Stay above and hold the line. Or descend into the mine to accelerate your growth. Mining fuels stronger builds - but leaving at the wrong time can cost the run. Greed is always a decision. Four Roles. One Team. Fighter - controls space and absorbs pressure Miner - accelerates economy and scaling Engineer - stabilizes lanes and strengthens defenses Medic - prevents collapse when mistakes happen XP is shared. Builds diverge. Survival is collective. New Depths Await The Abandoned Mine is only the beginning. Survive runs to unlock new regions: Forgotten Ruins Frozen Caverns Molten Depths Each descent brings new enemies, new pressure, and a different battlefield. Early Access Features 1–4 player online co-op ~15 minute structured runs Two map styles with distinct pacing Four regions to fight through A powerful mid-run enemy encounter Optional Endless Mode Card-based progression each run Persistent upgrades between runs No friendly fire Vision Chthonian TD is built around one idea: Relentless action, meaningful choices, and co-op that actually demands teamwork. Fight above. Mine below. Survive together.
