Andy got a board game called Giant Killer Robots.
The game’s premise involves human-controlled robots fighting for televised sport in a derelict city as an arena.

The game came with some really cool-looking robot models, but the arena and buildings were just flat cardboard and fairly uninspiring, so we needed an upgrade.

A laser seemed the most appropriate tool here, so I modelled and cut a few buildings and city streets in the game-appropriate hexagonal grid.

Within the game, teams of robots tag and destroy the buildings: which meant that the building models needed to be able to suport showing that they were tagged and/or destroyed.  …hence both the slots on the tops of buildings to hold little tags, and destroyed versions of the buildings to swap in at the appropriate part of the gameplay.
