Developers assumed that players would have a central world, from where they would move to different locations. Each task, mission and things in particular were unique. You could explore the cards with enemies or the collection of new equipment, so you can keep progressing through the story.
Among the tasks mentioned are mission to end targets, destroy weapon caches, and for that matter, issuing different locations and, as a whole, a priority. The game had to have a safe zone that would connect all the cards.
In addition, the project looks like it has added a cycle of day and night (and a change in the weather) and authors wanted to also include jetpacks in the shooter.
The players were apparently able to find some weapons and equipment, but could also acquire some other defense goods like barricades. It also had its own local currency system.
The creators of the project worked on that campaign for a little more than a year. But in 2014, they totally abandoned the concept. As a result, some of the details were added and transferred to the new version of the final game, which was released in November 2015.
In the photos of the last campaign, you can see two locations, several models with vehicles, and a set of houses with cars.
