_Ur anio 235_ is a first person 3D adventure game, with a gameplay similar to
Myst. It was designed to teach basic chemistry for high school students.
The player is abducted by an UFO and is sent to an abandoned village on
another planet. He/she is told that the alien people who lived there used
uranium as a power source, but one day a miscalculated neutron beam has hit an
uranium atom, causing a huge explosion, destroying most of the alien
population. Now the player’s mission is to deactivate the beam.
The game presents many chemistry subjects, such as matter, atomic models,
physical states of the matter, mixtures and separations, periodic table,
chemical bond, chemical functions, chemical reactions and radioactivity.
