In Mini War on Roblox, the “nukes” people usually mean are tied to the military building/shop progression, not a normal drop item. The most likely place to get them is the Shopkeeper’s military tab , where higher-tier military buildings unlock stronger units and weapons.

Where to look

  • Open the Buy/Sell menu and go to the military section.
  • Buy the higher-end military buildings there, since stronger units and advanced weapons come from those unlocks.
  • If you’re talking about a special or event-style item, some extra content in Mini War can also come from the Black Market , which appears near the leaderboard helipad and accepts gems.

Important note

The sources I found use both “Mini War” and “Mini Army” wording, so the name may be slightly off, but the upgrade path is the same idea: build up your army through the military shop and later-tier buildings.

Fast answer

If you want the shortest route: go to the Shopkeeper, open the military tab, and buy the strongest military building you can afford.

If you mean a different Roblox game called Mini Army , what’s the exact game link or full title?
