The Tidal WaveMartian ships now turned their terror to the sea.
You must control a Martian to play this card. Play this card at the beginning of your Hourglass phase. Choose a map edge. Move all monsters and victims one space away from the chosen edge, beginning with those furthest away. This movement is blocked by walls, blocking terrain, map edges, monsters and victims. If a monster cannot be moved, it is dealt 1 damage. All clear terrain is considered water terrain until the beginning of the next Hourglass phase.
