RoWorld Arsenal Tier List
Mega Nuke, Scattershot, Railgun, Reinforcements and the rest, graded by what they change.
The Arsenal is where RoWorld’s account-level progression lives. You earn Stars by playing matches and spend them, or pay Robux directly, to unlock permanent items that change how you play. There are eight items, and the prices are steep enough that the order you buy them in matters.
How Stars are earned
Every match pays out Stars across six lines: match played, time survived, land held, nations conquered, first place, and victory. Recorded payouts on ordinary matches have ranged from roughly 1,000 to over 3,000 Stars, and the 2x Stars booster doubles that total on the same match.
That number matters for planning. A 40,000 Star item is roughly 15 to 35 matches of income, which is a serious commitment for a free game.
S Tier — buy these first
Reinforcements — 149 Robux / 40,000 Stars
Pay gold to get 20 percent more troops at once, and it is ready again every 30 seconds. In a game where an attack commits a percentage of your standing army, a flat 20 percent burst is the strongest single combat item in the Arsenal. One recorder puts the in-match cost at around 100,000 gold per use, which is affordable in the mid game and decisive in a close fight.
2x Stars — 59 Robux
Doubles your end-of-match Star payout. A 1,035 Star match becomes 2,070. It does nothing inside a match, which is why it looks cheap, but it compounds: it halves the time to every other item in this list, and 59 Robux is the lowest price in the Arsenal.
A Tier — strong purchases for specific goals
Railgun — 999 Robux
A 50-tile blast radius delivered straight from orbit, and it is listed as not interceptable by SAM Launchers. That makes it the only weapon in the game that bypasses a full defensive setup. It is also the most expensive item in the Arsenal at 999 Robux, so it is a late-game purchase for players who have already built their economy.
Mega Nuke — 39 Robux / 20,000 Stars
Four times the blast of an Atomic Bomb, launched from a Missile Silo. At 39 Robux it is the cheapest weapon in the shop and one of the best values in the game — the only requirement is owning a silo, which the nukes and fallout guide covers. One community list places its radius at 45 tiles.
B Tier — worth it once the basics are done
Scattershot — 67 Robux / 40,000 Stars
Splits into four to six warheads that are targeted independently, and a single SAM Launcher cannot stop them all. It is a genuinely different weapon rather than a bigger bomb, which makes it more useful than its price suggests against a defended core.
Rapid Reload — 129 Robux
Reduces the wait between Arsenal activations. It is one of the cheaper items and it pairs well with Reinforcements, because the entire value of Reinforcements is the 30-second cooldown on each use.
C Tier — situational, save your Stars
Air Strike — 349 Robux
An air attack rather than a nuclear strike. It is one of the most expensive entries in the shop, its exact effect is not printed on the item description, and it competes for the same Stars that buy Reinforcements.
Artillery — 99 Robux
A conventional bombardment that does not create fallout. That is genuinely useful in the endgame, where a nuke would burn land you need to count, but it costs more than Scattershot and does less damage.

| Artillery | 99 Robux | Conventional bombardment, no fallout | C |
Recommended purchase order
Buy 2x Stars first, then Reinforcements, then spend the rest of your Stars on the weapon style you enjoy. If you plan to use nukes at all, a Mega Nuke plus a Missile Silo is the best long-term value in the shop, and the building tier list explains why the silo itself ranks low.
Frequently Asked Questions
Quick answers to the questions RoWorld players ask most.
What is the best item in the RoWorld Arsenal?
Reinforcements, which gives you 20 percent more troops on demand and is ready again every 30 seconds. For pure value, 2x Stars at 59 Robux is the cheapest entry and doubles your match payout.
How do you earn Stars in RoWorld?
By playing matches. Payouts are split across match played, time survived, land held, nations conquered, first place and victory, and ordinary matches have been observed paying roughly 1,000 to 3,000 Stars.
Is the Railgun worth 999 Robux in RoWorld?
It is the most expensive item, but it is the only weapon listed as not interceptable by SAM Launchers and it delivers a 50-tile blast from orbit. It is a late-game purchase for players who have already built their economy.
Do Arsenal items work in solo mode?
They are account-level unlocks tied to your profile rather than a match, so they apply wherever you play. Solo matches do not carry the same competition, which changes their value rather than their availability.
Should I buy the Mega Nuke or the Scattershot?
The Mega Nuke is cheaper and hits harder, but it needs a Missile Silo. Scattershot splits into four to six warheads that one SAM cannot stop, which makes it the better answer against a defended core.
