Nikopol: Secrets of the Immortals

The year is 2023 and Paris is governed by a power-hungry dictator. As Alcide Nikopol you try to find a way of joining the underground rebellion and help stop the dictator's iron fist rule. The history takes a turn towards the weird, as Nikopol finds out that his father - an astronaut sent into orbital exile in cryopreservation - may be alive and well in the city. At the same time, a strange pyramid hovers over Paris, and a rumour of Egyptian gods residing in it spreads like wildfire.
