Can you still play Chess in reach? I remember it was an Aprils fools joke by bungie but then they later decided to release it, I’ve never actually got round to playing it.

You can probably do a search and get a map too, or just make one.
That. All you gotta do to build a map is place a Hill Marker with label “BOARD_CENTER”. Give it about five units of empty space on all sides, and the gametype will do the rest. You can play on Forge World, Tempest, or Anchor 9. 
Just keep in mind, though: the game doesn’t end itself, even when the enemy King dies. You’ll have to end it manually.
