- 30 Floors Up best gun overall: the Minigun, with the Rocket Launcher as the AoE alternative for floor bosses.
- Early game: upgrade your Pistol first, then grab the Shotgun for stairwell chokepoints around floors 6–10.
- Ammo economy matters: burning cash on the wrong weapon slows your barricade upgrades.
- Best value pick: the Assault Rifle is the most reliable all-rounder for solo players.
- Save for S-tier weapons before pushing floors 21–30, where elite enemies punish weak loadouts.
Best Guns in 30 Floors Up: Tier Rankings
Your weapon choice determines how long you survive the night waves in 30 Floors Up. High-tier guns balance raw damage with ammo efficiency, while cheap early options fall off quickly once runners and brutes start spawning. Below is the tier ranking based on damage output, fire rate, ammo economy, and how hard each weapon is to unlock.
| Tier | Weapon | Damage | Ammo Efficiency | Best Use Case |
|---|---|---|---|---|
| S | Minigun | ★★★★★ | Medium | Shredding sustained night waves |
| S | Rocket Launcher | ★★★★★ | Low | Clustered groups, floor bosses |
| A | Shotgun | ★★★★ | High | Close-range chokepoint defense |
| A | Assault Rifle | ★★★★ | High | All-round mid-to-late game |
| B | SMG | ★★★ | Low | Early-to-mid transition |
| B | Crossbow | ★★★ | Medium | Precision single-target shots |
| C | Pistol | ★★ | High | Floors 1–2 only |
| C | Baseball Bat | ★★ | N/A (melee) | Saving ammo vs lone enemies |
| D | Slingshot | ★ | Low | Replace immediately |
Minigun (S-Tier)
- Massive sustained damage
- Shreds entire night waves
- High coin cost — save for it
Rocket Launcher (S-Tier)
- AoE clears clustered hordes
- Melts floor bosses in seconds
- Watch ammo costs
Assault Rifle (A-Tier)
- Best all-rounder
- Great damage and fire rate
- Strong ammo economy for solo play
Don't spread coins across your whole loadout. A single upgraded S- or A-tier primary carries you through far more nights than several half-upgraded weapons.
Best Gun by Floor Stage
The best gun in 30 Floors Up changes as you climb the tower. Threat levels, enemy types, and your coin income all shift from zone to zone.
| Floor Zone | Threat | Best Gun Pick | Why It Works Here |
|---|---|---|---|
| Floors 1–5 | Low | Pistol (upgraded) | Tutorial zone; conserve coins for upgrades |
| Floors 6–10 | Low–Medium | Shotgun / SMG | Small groups funnel into stairwell chokepoints |
| Floors 11–20 | Medium | Assault Rifle / Minigun | Serious night waves need sustained DPS |
| Floors 21–29 | High | Minigun + Rifle ammo | Elites and brutes demand heavy firepower |
| Floor 30 | Extreme | Rocket Launcher + Minigun | Boss fight plus wave adds |
Never bring a Rocket Launcher as your only weapon for the rooftop. Between boss phases, wave adds swarm from multiple stairwells — pair it with a Minigun or Assault Rifle so you're not caught reloading.
Floors 1–10: Build Your Foundation
Loot every crate, keep the upgraded Pistol for headshots, and buy the Shotgun when small groups start spawning. Funnel enemies at stairwells.
Floors 11–20: Commit to One Primary
Save coins for the Assault Rifle or Minigun. Fully barricade one staircase per floor and use chokepoint lines to conserve ammo.
Floors 21–29: Heavy Loadout Only
Field the Minigun with rifle ammo stocked. Fight exclusively at chokepoints, keep revive coins in reserve, and repair barricades between every wave.
Floor 30: Boss Setup
Max barricades before the fight. Focus fire the boss with the Rocket Launcher while covering stairwells against wave adds.
Matching Your Gun to Each Zombie Type
The best gun also depends on what's climbing the stairs toward you. Each infected type has distinct counters.
| Enemy | Threat | Best Gun Counter | Key Weakness |
|---|---|---|---|
| Shambler | Low | Pistol headshots / Shotgun | Groups up in hallways |
| Runner | Medium | Shotgun at chokepoints | Slowed by barricades |
| Brute | High | Assault Rifle / Rocket Launcher (headshots) | Slow turn, long recovery |
| Crawler | Medium | Shotgun / downward melee | Easy kill once spotted |
| Spitter | Medium-High | Rifle ammo at range | Long wind-up, low mobility |
| Horde Wave | Scales | Minigun | Predictable timing |
Kill Spitters at range before they zone out your barricade line, then focus the Brute while teammates repair. Standing in acid puddles while fixing defenses is one of the most common wipe causes.
Loadout Milestones:
- Upgrade starting Pistol before floor 6
- Buy Shotgun for stairwell defense by floors 6–10
- Own one fully upgraded A-tier or better primary by floor 15
- Stock rifle ammo for Brutes and Spitters past floor 20
- Save for Minigun before entering floors 21–29
Ammo & Economy: Funding the Best Gun
Even the best gun is dead weight without ammunition. Ammo costs add up quickly, especially with heavy weapons during long night waves.
| Ammo / Supply | Price | Best For | How to Get |
|---|---|---|---|
| Pistol Ammo | Cheap | Cost-efficient horde clearing | Shop / starting loadout |
| Shotgun Shells | Medium | Tight stairwell chokepoints | Shop |
| Rifle Ammo | Medium-High | Killing Brutes and Spitters | Shop / higher floors |
| Ammo Box | Medium | Refills reserves mid-run | Shop / wave rewards |
| Bandage | Cheap | Topping up between waves | Shop / floor loot |
| Medkit | Expensive | Emergency heals mid-wave | Shop |
Repairing a damaged barricade costs far less than replacing a destroyed one. Assign one teammate as dedicated repairer and keep their Repair Tool stocked — every coin saved on barricades goes toward your Minigun fund.
FAQ
Q: What is the best gun in 30 Floors Up overall?
The Minigun is the best gun overall thanks to its massive sustained damage that shreds night waves. It has a high coin cost, so treat it as a long-term save goal. The Rocket Launcher is the strongest alternative when you need AoE damage against clustered groups and floor bosses.
Q: What is the best gun for early floors?
On floors 1–10, an upgraded Pistol paired with a Shotgun is the most efficient setup. Pistol headshots conserve ammo against shamblers, while the Shotgun's close-range burst is ideal for the stairwell chokepoints you'll build around floors 6–10.
Q: Should I upgrade one weapon or spread coins across several?
Upgrade one reliable primary instead of many weapons. Early coins are scarce, and a single strong Assault Rifle or Minigun carries you through far more nights than a loadout of half-upgraded guns.
Q: Which gun should I bring to Floor 30?
Bring your best upgraded loadout — typically a Rocket Launcher to focus the boss plus a Minigun or Assault Rifle to handle wave adds. Max your barricades before the fight and rotate between stairwells as needed.
