The Keys to the Portals
This is indeed a very strange world.
When the runners target someone a ring appears around the target’s feet, but is only visible to the one doing the targeting. The ring’s colour indicates if the target is friendly, hostile or neutral. I.e. if Kitty targets an enemy she will see a red ring around its feet, if she targets a (neutral) squirrel there is a yellow ring and if she targets Mike Hawkins there is a green ring.
Apparently it is not possible to do friendly fire in this world as it was impossible for the runners to shoot (with paintball guns) at each other…
The few enemies they encountered have all been ridiculously sturdy and after dying their bodies have slowly faded away after a few minutes.
