This past weekend I finally got to play Tactics (yes, I'm late to the party, and parking was difficult).
We were a little confused about Turret Bot at first--mostly about range, but it seems that doesn't factor into attack dice since they're hazard spaces. We're less confused now, but I'm not entirely sure about line of sight issues.
Specifically, does Turret Bot need line of sight to all affected hexes to create hazard spaces and/or attack targets that trigger the spaces? Since hex elevations can change between the time the hazard space is created and when it is triggered, this is a two-part question.
By contrast, Ra's Blazing Tornado specifically states that the hazard space can be created on a space that Ra has line of sight to, and there's no similar qualifier on Turret Bot's card. Other hazard spaces are triggered even if the entity in charge of the space doesn't currently have line of sight, though that's hard to picture since Turret Bot is, thematically, laying down suppression fire from his position (even though that's not necessarily how it translates to game mechanics). So I'm not sure of the correct way to play it. This may be a case where game mechanics override theme, or vice versa.
