Thus Veillot's families were similar to the Linnaean genera, with the difference that shrikes were no longer included amongst the birds of prey. In addition
Prey 2 lifeforms from the intelligence that controls it, before returning to earth. "Prey 2" was to focus on U.S. Marshal Killian Samuels, who starts the game on a passenger flight which suddenly crashes onto the Sphere, shown during the events of "Prey".
