Store description excerpt
Once, the world was protected by water. The setting is a desolate world where sewage treatment plants have ceased to function. Your mission is to purify the encroaching polluting life forms, "Prederia" and "Polutant," alongside the microbial commanders "Bacter" and "Bactimon," and restore the world's water. Supervised by Meidensha, a social infrastructure company with over 100 years of history! A new kind of tower defense game that makes learning about the sewage treatment system fun. 【Features of this game】 ▶︎ A "flowing" tower defense that defies convention Unlike conventional games where attacks come from the left and right, this game employs a unique battle system where "enemies and allies flow in the same direction along the water flow." On a field modeled after the "reaction tank," the heart of a sewage treatment plant, purify the continuously flowing polluting life forms, "Polutant," with the power of the microorganism "Bactimon"! ▶︎ Realistic Water Quality Indicators are Key to Strategy BOD (Biochemical Oxygen Demand), SS (Suspended Solids), T-N, T-P… Equipped with an "attribute" system based on actual water pollution indicators. Furthermore, utilize real-world equipment such as "aeration devices" and "return sludge pumps" to efficiently purify the water! ▶︎ The Ultimate Balance: Water Quality × Power × Time The key point is that simply purifying the water isn't enough. Overusing equipment consumes "power," lowering your evaluation. Develop the best purification plan within limited time and resources! ▶︎ Battle Voices by a Star-Studded Voice Cast Unique characters are brought to life through action voices by talented voice actors! (*There is no voice acting in the scenario part) [Voice Actors (in alphabetical order)] Maaya Uchida, Yuri Sakamoto, Ayane Sakura, Takahiro Sakurai, Rina Sato, Asami Shimoda, Akihiro Tajima, Mutsumi Tamura, Jun Fukuyama, Kouki Hoshino, Aoi Yuki, Yui Watanabe ▶︎Official X https://x.com/GesuiOkoku ▶︎Official Website https://meidensha.co.jp/gesui-okoku
