"Humanity meets aliens for the first time" is a very popular subject for science fiction. What would happen if we were suddenly visited by a more-advanced alien race? Would we welcome them to Earth or would we "Welcome to Erf!" them, if you know what I mean? Well, a lot of that would depend on whether the visitors were friendly or hostile. First Contact: X-Corps goes that second route with their new RPG that's up on Kickstarter now.
In the game, players take on the role of members of X-Corps, a special defense force designed to repel the Chandra (as they're known), whose ever-increasing attacks on Earth foretell of an imminent invasion. Or, instead, you can be one of the many bystanders, simply caught up in the middle of this interplanetary war that's found itself planed in your front yard.
The campaign is around 2/3 funded with still 29 days to go.
