Costs and conflicting context
The RobloMine HUD frame has nuclear buttons at 750K, 5M and 25M. AllThingsHow lists Atom Bomb 750K–1M, Mega Nuke 2.5M, Hydrogen Bomb 5M and MIRV 25M. The different weapon lists and contexts do not establish one current price schedule. Each source remains identified separately, checked 27 October 2026.
AllThingsHow’s separate price table lists a silo at 1M and SAM at 1.5M–3M; its city and factory tiers range from 125K to 1M. The silo and SAM figures differ from the historical HUD. Upgrade, mode and recording-date context is not fully established, so we preserve both records without selecting or averaging a current price. Checked 27 October 2026.
What a SAM can establish
AllThingsHow reports a 70-tile SAM radius and distinguishes MIRV behavior from ordinary interception. This is a single publisher, not a guarantee that every nuclear weapon can be stopped. No calibrated damage, blast or interception model is supplied.
When to consider a launch
Editorial advice drawn from public guides: preserve your economy, identify the target and plan the follow-up expansion before spending on a weapon. A nuclear purchase alone does not establish victory; the official and independent guides still describe an 80% land goal.
