The game is inspired by true events from World War II. Some of the content is referenced from incidents that occurred in Asia during the war. We made this game not only to let players have fun but also to remind you how science may end up without an ethical boundary. We believe a game is a medium to inspire people, not just made for pass the time.-----------------------------------------Background:In 1941, Ishro and his followers established the Epidemic Prevention and Water Purification Department to operate medical and biological experiment for NanoMonster’s community. The research that Ishro had conducted earned a great reputation at first.But soon, some of the NanoMonsters discovered that Ishro and his researchers had brutally abused participants during the scientific experiment. All the unfortunate participants were from Nanotadps' community. Although the scientific research significantly helped NanoMonsters’ community, the majority of NanoMonsters criticized Ishro. Some of the NanoMonsters argued that it was not moral to conduct experiments on Nanotadps no matter how it helps to advance the science. On the other hand, some agree that Ishro’s experiment was beneficial to NanoMonsters’ society as a whole.In the end, the majority of NanoMonsters voted to end the research. The Epidemic Prevention and Water Purification Department was closed. However, Ishro did not give up his research nor his ideology. He and his followers created an ideology, Greatest Science Principle, and received support from notable NanoMonster scientists.Soon, Ishro reopened Epidemic Prevention and Water Purification Department. He and his supporters become the major contributors in technology and science. Now, Ishro wanted to eliminate all the opponents who against Greatest Science Principle. He created the Biochemical army and cloned Nanotadps to fight for him. The battle between justice and evil is inevitable...--------------------------------------------------Story Mode:You can defeat enemies to unlock items and characters in the story mode. Most of the characters can be unlocked by completing achievements. You don't need to purchase certain NanoMonsters to unlock them. But we will be very grateful if you support our game.It is important to know that aiming the target using touchscreen is extremely hard. Therefore, we created "Moving Attack" system. You can move a NanoMonster by touching left-half of the screen and long-pressing right-half of the screen to aim at the specific target. The trick would be very useful when you shoot at target enemies.--------------------------------------------------Endless Mode:You can unlock endless mode only when you defeat all the enemies in story mode.--------------------------------------------------Nanotadps Scene:We decided to include the scene in the game for fun.------------------------------------Credits:Game Art by Jin,XionglongGame Programming by Cui,LongchangMusic - System Shock by Neocrey Studios.Many thanks to Neocrey Studios for the royalty-free music.https://www.youtube.com/channel/UC8lL7-LvRBjNQadXeY8O5zwSound effect - AntisampleMany thanks to Antisample for the royalty-free sound effect.https://antisample.com/Everything else, including testing, game experience, story, game effect etc. by Jin and Cui.
