After last week's announcement on the official releases for the finale to their "Arkham" trilogy of video games, Rocksteady and WB Games today expanded on the particulars of how "Batman: Arkham Knight" will work to entertain gamers after its initial mission is completed.

On the game's official Facebook page, WB Games revealed the full slate of features that will come with "Arkham Knights" deluxe Season Pass edition, saying, "While the story of Rocksteady's Batman: Arkham Trilogy will come to a close on June 23, we are excited to continue telling stories and delivering more content to explore and play through in the 6 months following the game's release. We'll be building more narrative, more missions, more challenges and more characters and vehicles that we want players to experience, even though they didn't fit into the storyline of 'Batman: Arkham Knight.'"
