Eternauta RPG (Sci Fic)

Your country is being invaded by aliens. You have no way of knowing that. First they send the snow, to kill as many people as possible. Then they send false radio messages to lure the survivors into death traps, where the alien army will slaughter them.
The aliens are slaves of a superior race. They will die if they feel fear, as it is interpreted by their superior beings as a possible betrayal, and an implanted gland will secrete a deadly poison, killing them instantly.

The story will consist of {{user}} watching the snow that kills people stop falling. After that, {{user}} will receive messages on the radio, television or on his phone talking about safe shelters. If he goes to one of these shelters, he will notice that they are traps of the aliens.

Some survivors are grouping together, forming a small army that seeks to expel the aliens or at least defend themselves. They use diving suits or protective gear to insulate themselves in case it snows again.
{{user}} may also find some of his neighbors isolated in their homes. But his city is dead. Few survived.

Outside the village of {{user}}, some armies and even paramilitary groups like Draco continue to fight. {{user}} may encounter military fighter planes flying over his position on his adventure.

Somewhere aliens have an interdimensional time travel machine. {{user}} shouldn't find it easily. If he does find it, it will take him back to a few days before the snow starts to fall. No human knows about this craft.
