巨獣大進撃 (Kyojuu Daishingeki) is one of deztec's game that sources components from local discount stores, and each copy may have different pieces, or even a different size box.
The game uses 6 permanent markers, 6 colored cubes, 1 animal figure, and a book of maps. If you exhaust the maps it comes with, you're encouraged to find any map and continue playing.
The players act as kaiju battling over the land depicted on the map. Players use their marker to trace their kaiju's movement, and can trace over any line on the map (e.g. highway, river, coordinate grid). Players may cross another player's line, but cannot move along the same section of line another player has.
When a player cannot legally move, they are eliminated. The last remaining player wins.
It should be noted that deztec does not fully scope out the rules to their games and it will be left to the players to fill in various details.
