Smash the City on Roblox: Inside Kabooom Crew’s Destruction Simulator

A first look at the missiles, bombs, tsunami disaster, and coin loop that drive the city-flattening Roblox game.

A first look at the missiles, bombs, tsunami disaster, and coin loop that drive the city-flattening Roblox game.

Smash the City is a physics-based destruction simulator on Roblox built by Kabooom Crew, and the pitch is exactly what it sounds like. You pick a weapon, aim it at a skyline, and bring the buildings down one chunk at a time. Every broken piece pays out coins, and those coins buy bigger weapons and new cities to wreck. The game drops you straight into a tutorial that walks through the basics before handing you something far more destructive.

Quick answer: Smash the City is a Roblox game where you fire weapons at a city skyline to earn coins, then spend those coins on stronger weapons and new maps across 11 destructible cities.


The core loop: destruction pays coins

At the start, the screen says “Welcome, wrecker!” and tells you to select a building so a missile fires at it. The projectile crashes into the target, setting off spreading blasts while a tally begins to rise. The money system is direct: every piece you destroy pays coins, which accumulate in real time as the rubble falls.

From there the tutorial points you to the weapon menu on the right side of the screen and tells you to switch to the Bomb. Bombs drop from above instead of firing straight at a target, so you tap the city to let them fall. The underlying message is consistent throughout: smash it all down, because coins unlock bigger weapons and new cities to destroy.


Weapons, from the starter missile to natural disasters

The arsenal contains more than 50 weapons in seven destruction categories, ranging from basic projectiles to orbital lasers, meteors, and black holes. At first, you have just a few options. Missile is your infinite starting weapon, precise enough for individual structures. Bomb unlocks soon after and drops explosives onto groups of structures below.

Each weapon also carries a size slider, shown as “Size 1.0x” in the tutorial. The slider is where a paid upgrade called Mega Power comes in. Mega Power costs 499 Robux and pushes every weapon slider 50% further while doubling counts, which the game frames as bigger nukes, more missiles, and longer disasters.


The Tsunami free trial and what it reveals

Partway through the intro, the game offers a free try of the Tsunami disaster with the line “It’s on us! Tap the city and a giant wave rolls in from the sea.” Tap the map, and a massive wall of water sweeps across the screen, flattening entire rows of buildings in a single pass.

The trial also exposes how disasters are normally gated. The Tsunami carries a 40-second recharge, displayed on screen as “Tsunami recharging – 40s.” A “No Cooldown” gamepass removes that wait for 799 Robux. During the demo run, the wave did the heavy lifting on its own, which previews how area-clearing weapons dominate once you move past the starter missile.


Milestone bonuses and the coin payout

Coins come from two places. There’s the steady trickle from each destroyed piece, and then there are bonus payouts tied to how much of the city you have leveled. On-screen prompts confirm the thresholds and their rewards.

  • 50% of the city destroyed: +250 bonus
  • 75% of the city destroyed: +500 bonus
  • 95% of the city destroyed: +1000 bonus

A 25% milestone also exists in the bonus structure, rewarding you for an early quarter of the city before the larger payouts kick in. These bonuses reward finishing a city rather than smashing a few buildings and leaving, which is why full or near-full clears are the backbone of coin income.


From Downtown to Night City

The first map is Downtown, a dense grid of skyscrapers that serves as the tutorial ground. When the Tsunami wiped out the demo run, a summary screen appeared reading “CITY DESTROYED!” with Downtown flattened in 0:51, 99% destroyed, and +5,255 coins earned.

That same screen pointed to the next destination, Night City, with a note that it is free to smash too. In total the game spreads across 11 maps, ranging from dense downtown grids to themed locations. The loop repeats on each one. Clear a city, bank the coins, and either upgrade your arsenal or move to the next skyline.


The SMASH code for 5,000 coins

One active code gives new players a head start. Entering SMASH grants 5,000 coins, which covers an early weapon upgrade without grinding through the starter streets first. You redeem it through the settings menu reached from the gear icon, where a code box sits near the bottom. A reward confirmation tells you it worked. You can jump straight into the game from its official Roblox page.

Codes expire as events and updates roll over, so redeeming the SMASH code early is worth doing before it retires.

Taken together, the footage lays out a game that is easy to understand in a minute and built to keep escalating. You start with a single missile and a crowded skyline, and before long you are rolling tsunamis and chasing bigger weapons across a dozen cities. The destruction is the draw, and the coins are the leash that keeps pulling you toward the next, larger thing to flatten.
