    • A couple of new Pokemon have been added that are exclusive to AR with Gun Version… play the game to find them.

Current Known Bugs

  • Mewzero will not obey commands due to a quirk in the game’s programming.
  • The Town Map has not been properly updated to include the new areas; Flying from those locations is not advised.
  • The moves Ice Fang and Ice Shard are able to be used in the field unintentionally.
  • The graphics on the pause menu are slightly garbled, but the text can still be read. Marked as low priority.
  • Similarly, the Pokedex can be very finicky; it is advised to save before perusing it.
  • The NPC Cue Ball Paxton will crash the game if battled; his fight has been removed, but be aware of any fuckery upon arriving at Three Island.
