Why are people under the impression that Rust is a post Apocalyptic game?

[Zombiewarpig]

I don't see anywhere that it is such. I also don't see anything in the description of being a caveman ( There are no caves ).

Is it because of zombies or maybe the radiation?

Because everyone compares it to DayZ, and it causes confusion. Also Zombies have been removed from the game.

Taken from steam storepage:
"[B]Warning:[/B] Contains[B] violence[/B] and [U]caveman themed[/U] [B]nudity[/B]."

Radiation in abandoned towns, zombies that then got eaten by rabid animals are pretty strong clues to apocalypse.
I don't see how radiation can exisit in caveman times. Other clues that it isnt a caveman's world - tarmac'ed road, helicopters, loots with tinned food/military weapons.

Radiation = nuclear disaster, either from war, reactor accident, manufacturing disaster (eg: nuke submarine)...
All are human caused issue that poison the environment in large scale = apocalypse.

I always thought it was set. In the year 3219 and we crash landed on an alien planet, all our spaceships were destroyed and we were plummeted back to primitive times. Without our technology we were forced to make primitive automatic machine guns and ammunition, instead of the laser weapons we had.

Seriously though, interperate it as you like, we have no back story yet.

I heard that the alien base is out in the wasteland.

Zombies formerly, Radiation, radiation pills, what else could it be? End of days makes more sense than beginning of days (modern guns, airdrops, etc.). If it was to be considered anything else you'd have to remove modern guns imo.. I liked the zombies personally and the whole theme of it.. it wouldn't be a DayZ clone even if it had zombies... this game offers so much more imo... well now less bc no zombies lol.
