Destroy the Sun Ice Cannon: Cost, Stats, and Upgrades
The Ice Cannon is the first purchasable firearm in Destroy the Sun, bought for $225 at the RV upgrade computer to replace manual ice throwing with a rapid stream of ice cubes.

The Ice Cannon is the first purchasable firearm in Destroy the Sun, bought for $225 at the RV upgrade computer to replace manual ice throwing with a rapid stream of ice cubes. It draws ammunition straight from your backpack capacity, allowing you to pelt the sky continuously rather than charging individual throws by hand.
How Do You Unlock the Ice Cannon?
The Ice Cannon is an early progression weapon that unlocks immediately after you finish the opening tutorial steps in the RV. When starting out on the beach, you begin with standard ice cubes held in your hands, cooling the sun down from its starting temperature of over 144,000°C.
To purchase the weapon, walk into the RV and interact with the terminal computer. The purchase flow requires three direct actions:
- Throw starter ice cubes at the sun to generate your initial funds.
- Complete the tutorial prompts displayed on the RV computer screen.
- Select the Ice Cannon purchase option for $225.
Buying this weapon automatically awards the Locked And Loaded badge, as shown on the official Roblox game page by creator Lapis Works. Once purchased, holding down your primary fire key unleashes a steady stream of projectiles directly toward the target reticles orbiting the star.
How Does the Ice Cannon Compare to Other Weapons?
The Ice Cannon is a rapid-fire projectile launcher that bridges the gap between hand-tossed cubes and mid-tier beam technology. While it lacks the raw stopping power of later gear, its fast firing cadence allows you to hit moving weak points consistently.
| Weapon | Unlock Cost | Primary Role | Resource Trade-Off |
|---|---|---|---|
| Starter Ice Cubes | Free ($0) | Early manual cooling | Requires manual charge-up per throw |
| Ice Cannon | $225 | Rapid stream bombardment | Drains backpack capacity very quickly |
| Cryo Ray | $16,000–$16,500 | Continuous cold beam | Consumes massive ice volume per second |
| Comet Catcher | $38,000 | Heavy burst meteor impact | Requires catching falling comets before firing |
The weapon relies entirely on your backpack reserves. If your capacity is low, firing the stream empties your clip in seconds, forcing you to step back to the ice dispenser inside the RV.
Which Upgrades Benefit the Ice Cannon Most?
Stat investments made at the RV computer significantly improve the efficiency of the weapon during extended runs. Because the gun consumes ammunition rapidly, balancing capacity with output provides the smoothest pacing through general upgrades.
Backpack capacity is the most critical companion stat for the Ice Cannon. Starting at basic caps like 5 or 8 cubes, upgrading your pack allows you to reach 19, 39, 55, and eventually over 140 cubes. Higher capacities let you maintain sustained fire on the sun's target circles to harvest falling cash and items.
Cooling power upgrades increase the temperature drop delivered by every single projectile. Because earning money scales alongside cooling effectiveness, raising this stat speeds up your path toward mid-game gear. Attack speed enhancements increase projectile velocity, turning the weapon into an SMG-like stream.
How Do You Handle Combat During Solar Instability?
Solar Instability events occur periodically as the sun loses heat, temporarily raising an immune shield over the star and spawning hostile creatures around the sand. When these waves trigger, the game grants temporary infinite ice, letting you fire the Ice Cannon without refilling.
Early waves send out basic Solar Ghouls that march toward your character. Aiming for headshots deals critical damage, eliminating standard ghouls in a few hits. As the heat drops further, enemies like the laser-firing Solar Eye, the health-draining Leeching Wisp, and the armored Pumpkin Reaper enter the field. Backpedal across the sand while spraying the Ice Cannon into the cluster to clear the board and reopen the sun to direct attacks.
