Demain Holocauste (F) (1986) [a1] - Amstrad CPC - Adventure, Sci-Fi

It is in the brotherhood of the five planets Tera, Acia, Luna. Alfa and Pira let the whole story happen. When you arrive on site, the countdown has already started since there are only 180 hours left to live in the constellation of Vega. This survival delay is due to a cloud of radiation of unknown origin which is progressing slowly but surely. The only effective weapon against it is the ARX 11, lost on one of the five planets. Your mission is to find her within the time limit. You will first need to equip yourself according to your means and then carry out your investigations on all the planets.
