About Classified Part Underground Facility
v2.4.0 - "THE POWER OF THE REPUBLIC" All the action takes place in 1983, where nuclear science has succeeded thanks to the High Science Corporation. In order to protect and control the privacy of their achievements, this facility, commonly referred to the cpuf, was built. An experimental controlled fusion reactor based on the "Little Sun" was created in the facility. Most people were interested in this achievement, especially their main enemy, the "Chaos Forces". The usual night shift will take place today. Some facility security systems were temporarily disabled for maintenance. This night shift may be decisive in the history of High Science. You are one of those who can influence further events. DISCLAIMERS: ▷ For best gameplay, play with headphones and set the graphics quality to 5–10!
