Compare Nucleum base-game and Australia accessory bundles, plant-only choices and LED options. Avoid duplicating the plants in a complete configuration.
Choose the scope before the lighting
The selectable component groups are Base game, Base game + Australia expansion, Only nuclear plants and x1 Power Plant. Each has With Led and No Led selections. First decide which pieces you need; then choose the lighting option.

Base-game components
The base collection lists four nuclear plants, one coal factory, one smokestack, 16 turbines, 16 mines, 25 gold-colour coins, 20 silver-colour coins and a starting-player marker. Only nuclear plants is the narrower plant group: four plants, one coal factory and one smokestack. The single-plant option is smaller again.
What does Australia add?
The combined base + Australia configuration adds one plant, 16 player ships in four colours, three neutral ships, 16 mines and eight neutral coal mines. It already contains the base collection. An Australia-only option is not among the current variant selections; do not assume it can be selected separately.
Choose the combined bundle if you want both groups. If you already own base upgrades, compare the overlap carefully before ordering. The accessory does not include the Australia expansion, its map or cards.
Check the exact LED selection
Product photos can show illuminated pieces, but lighting is optional. A No Led selection does not acquire lights because the gallery shows them. This guide does not specify battery type or battery inclusion. Confirm those details if they affect your choice, and check other expansions separately.
Reference and context
The Australia expansion entry provides context for ships and the new map. It describes the expansion, which is separate from the accessory bundle. Read the source.
