Infection Xconsists of a virus which must infect cells, fight against antibodies, destroy white blood cells....
At the moment, there are 3 types of puzzles: pulmonary, in which the virus must explore, fight against antibodies, destroy white blood cells, overcome obstacles, etc; cellular, in which the virus, playing with inertia and jumping, must reach the nucleus to be able to replicate after performing a kind of 'parkour'; and finally the nuclear puzzle, which is a kind of maze in which you must reach the chromatin without hitting the walls. There are different types of enemies and there is a boss at level 7.
Just play and have fun!
