A Kotama and Academy Citadel Steam Key — also known as a CD Key or digital code — is the official activation code you redeem on Steam and keep in your library permanently. From €15.50 (-1%) at Fanatical · 5 verified stores, 7 offers in stock · Updated 49min ago.
Welcome to Carmel, an Academy Citadel renowned for its cutting-edge technology, where survival of the fittest is the only law and strength reigns supreme.
The "Carmel Star" —symbolizing the ultimate honor— is the goal students dream of. As the Centennial Anniversary approaches, a new "Carmel Star Election" is about to begin.
You represent a mysterious "exchange student" who suddenly appears, determined to join the competition.
To get the Carmel Star you will have to explore the sprawling labyrinth that is the Academy Citadel, a treacherous place where technology can unravel reality itself with mind-bending illusions, impossible machines, and self-contained biomes.
Each area demands mastery of your fluid powers. Use your special abilities to overcome deadly traps. Return to previous zones with your newfound powers to uncover secrets hidden behind illusory walls and locked gates, revealing shortcuts and unexpected treasures.
In this Academy where "survival of the fittest" is the only law, exceptional power is the key to turning ambition into reality.
Master Kotama's unique fluid constitution to weave through hordes of bizarre enemies with blistering speed. Switch weapons seamlessly, combining them with skills and Memocards to chain dazzling combos. When your energy peaks, unleash a Fluid Detonation to wipe the field in a flash.
Different sections of the Academy Citadel are guarded by powerful creatures or robots that will stand in your way to the dreamed Carmel Star. They all have unique attacks and game mechanics, but all are strong enough to destroy you in a heartbeat; it will take all your skills to emerge victorious.
Master your opponent's patterns, parry at the critical moment to neutralize lethal strikes, and break their stance. As you enter bullet time, seize the fleeting openings to deliver a decisive, crushing blow.
You are not completely alone in this adventure – there are other peculiar, captivating students scattered across the Academy Citadel! Aid them during your journey, uncover their stories, and earn their loyalty as allies in your search for the Carmel Star. What might seem like a small choice at the moment could make a real difference and end up saving the Academy and deciding your fate.
The Academy Citadel welcomes challengers of all kinds, offering a range of difficulty settings to suit your style. You can choose to immerse yourself in the rich narrative and the joy of exploration on a laid-back difficulty—checking every nook and cranny for gear, weapons, and upgrades to optimize your build. Or crank up the challenge for intense, skill-focused combat that pushes your mastery to its absolute limit.
Kotama and Academy Citadel for PC starts at €15.50 at Fanatical, a Steam key, which is 1% under the €15.60 it costs on the official store.
Supply is thin — 7 offers from 5 stores — and thin supply keeps prices steady rather than falling.
That puts it 21% under its average of €19.50 since 2026, so today is a better entry point than most days of its life.
That €15.50 key is at one of its best prices.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
By format: Steam Key from €15.50 and Steam Gift from €17.76.
