About this game
MK-ULTRA Psychic Defense is a rogue-like tower defense game where you will use unique esoterically themed towers to defeat waves of mind goblins and obtain unique power ups that will empower and improve your towers.
In MK-ULTRA Psychic Defense you play as a victim of the MK-ULTRA program, a young Ted Kaczynski, you have been unknowingly dosed with a highly experimental psychedelic compound in order to astral project your mind into the Psychosphere. Your CIA handlers wish you the best of luck in defending your Kundalini energy spiral from the waves of lower dimensional entities seeking to return your soul to the illusion of physical reality.
Key Features:
🗼 Roguelike Tower Defense — Unlock occult towers, place them on the field, and build your defense across escalating waves. Each placement costs more Gnosis, forcing hard choices about when and where to commit.
📜 The Akashic Records — A full occult marketplace between waves. Spend Gnosis — the currency of enlightenment — on tower unlocks, conspiracy cards, consumables, and upgrades.
🔮 Conspiracy Theories — Persistent passive modifiers across 5 rarities that bend the rules of reality. Stack synergies, trigger effects on kills, tower placements, and incoming damage. Every run builds a different play style.
🗼 13 Occult Towers — Pyramids, Ankhs, Time Cubes, Emerald Tablets, Death Fungi, Cosmic Eggs, and more. Each with unique attack patterns and inter-tower synergies that reward creative placement.
🧊 The Conspiracy Theory Iceberg — 141 real conspiracy theories to discover through gameplay. Browse your collection. Go deeper.

Psychotropic Warfare (1v1 versus)
- **Open the Laboratory menu and click "Psychotropic Warfare."** Host a lobby, invite a friend (or they join off your Steam profile), and the match starts once you're both in. Friends-only, 2-slot lobbies over Steam.- **Real towers, real enemies, real physics.** Versus runs the actual game on the host — every tower, card, consumable, and enemy behaves exactly as it does in solo. No simplified sim.- **Offense is direct:** click one of the portals on your opponent's board to send a wave of enemies through it. Each send costs more Gnosis than the last (shared, escalating per match), and a bigger spend sends a nastier batch. Sent enemies stream in through the portal you clicked.- **Fair by construction:** both boards are generated from the same seed and mirrored, so you and your opponent face identical terrain and waves.- **First to leak loses.** Boards start at 100 HP; when one player's defense breaks, the match ends.Read full article on Community Announcements (zerosequels)Patch NotesOfficial
