What is confirmed
Kill Block is built from 3 Slabs. Activision states they can produce more than 500 configurations at launch, which means the layout you memorised last match may not exist this one.
How to play it
Treat every match as a new map. The routes you learn are for one configuration only, so the habit worth building is checking openings before committing rather than running a remembered route.
Which modes run on it
Activision describes Kill Block hosting Gunfight formats, including 3v3 and Gunfight 10v10. Which modes appear on it in a given playlist can rotate, so check the playlist rather than assuming.
