Status: TOP SECRET! INSTRUCTIONS: 1. Activate the particle generator and create Hydrogen atoms, the atoms will begin to produce energy. 2. Combine two Hydrogen atoms and get a Helium atom, this will give you much more energy. 3. Merge identical atoms and move forward along the table of chemical elements, extracting more and more energy. You can get a lot of useful information by double tapping on atoms. 4. Accumulate energy and use it to improve the laboratory and access new technologies. 5. Complete tasks and increase your scientific status, this will open access to experiments with antimatter and neutrinos. 6. Develop your laboratory and gain access to working with a nuclear reactor and hadron collider. 7. Form and train your own team of brilliant scientists to develop technology. What is inside? Offline – full functionality and performance of the application without access to the Internet. Play anywhere anytime! Idle - play only at a time convenient for you, and while you are busy, ATOM Inc. Idle will take over the gameplay. Just don’t forget to upgrade the “OFFLINE” function, then your progress will be even more noticeable! Simulator of a scientific complex - choose your own strategy for the development of the complex: increase energy by pumping the reactor or extract antimatter by developing a collider, or maybe it’s better to put more effort into expanding the staff of scientists and their training. Your game is your development plan, your decisions, you are in charge here! Merge – there will be many, many mergers. Combine two Hydrogen atoms and get Helium, two Helium will give Lithium, and so on until the very last element discovered by science - Oganesson. Each combination means an increase in energy production. Merge manually or use automatic merging. And if you double tap on an atom, you will get real interesting facts about it! About each of them!!! Clicker – speed up the process of generating atoms using clicks. As a gift for such activity, you will have access to experiments with the production of antimatter, and this is a very useful resource!!! Tycoon - you have a huge scientific complex at your disposal, develop it, organize the expansion of research tools, choose a development strategy, open new divisions and departments. Incremental - the core of the game logic is the growth of various indicators: energy production, antimatter production, neutrino accumulation, growth of knowledge, number of open atoms, etc. This game will be a pleasant find for connoisseurs of Idle and NGU Download for free, join the community, love science!!! https://z21795818.app-ads-txt.com
