Merge a Nuke's PvP loop is asymmetric by design. Enemy players can launch their highest-tier nukes at your board and wipe out quintillions of stored value if your Base Lock is down.
The baseline 20-minute Lock cooldown is long enough that AFK players are guaranteed to lose something eventually. The 79 Robux Quick Lock Cooldown gamepass is the most cost-efficient defensive purchase.
x2 Nuke Health at 199 Robux doubles your board's durability, but only matters during the brief windows when Lock is down. Don't pay for it before Lock.
City raids — the main PvE cash source — never damage player bases. Confusing the two is the single most common newbie panic trigger.
