1.2.10 Maps: Any WizKids-created HeroClix map is considered official, with the exception of maps from Star Trek: Tactics. Official 36- by 36-inch maps (3 x 3) can be used in any HeroClix event. Official 24- by 36-inch maps (2 x 3) can be used in any HeroClix event when only two players are playing on that map. Maps of other sizes – even those created by WizKids – can’t be used in a HeroClix event. Venues may dictate that maps are restricted to 2 x 3 maps if space issues are a concern. Venues may dictate for an event that only a particular map (or maps) will be used for any or all of a specific round, though this should be announced prior to the event. All WizKids sponsored events will only permit the use of maps that include the color designations for terrain and starting areas.
