The Portal

Time travel is real! Scientists in our area, Oppenhofallee, have discovered a tear in the space-time continuum and have been researching it. Unfortunately, it was discovered that an apocalypse awaits us in the future (see "Aachen - the last refuge"). A virus has wiped out a large part of the population, only a few pitiable creatures have barricaded themselves in underground bunkers and lead a dreary existence. But there is hope! The scientists have discovered that a certain Dr. Nobel has developed an antidote (see "The Discovery") and his notebook with this important information is on display in a museum in the future. Your task is: Step through the portal into the future! Get the notebook! Come back to the present and save humanity!
