☢️ Nuke Your City Upgrades & Machines – Complete Guide
This is the definitive reference for every upgrade in Nuke Your City. We cover Dropper levels, all Machine types, upgrade priority order, cash management strategy, and the best build for each phase of the game. For a ranked summary, see the Tier List →
⚙️ The Dropper – Your Core EXP Engine
The Dropper is your starting machine and the foundation of all progression in Nuke Your City. It automatically generates EXP and feeds it into your Explosive. The higher your Dropper level, the faster EXP accumulates — and since EXP scaling is exponential, even a single Dropper level gained early in the game has compounding returns over hundreds of future launches.
New players frequently make the mistake of buying Machines too early. The Dropper is always the first investment. Without a strong Dropper foundation, Machines have far less to multiply — and your EXP fill rate remains the bottleneck throughout the entire run.
Dropper Upgrade Benchmarks
| Level Range | Phase | Strategy | ROI |
|---|---|---|---|
| 1–5 | Foundation | Buy all 5 levels before any Machine purchase | Very High |
| 6–10 | Growth | Alternate: 2 Dropper levels → 1 Machine | High |
| 11–20 | Mid Game | 1 Dropper level → 1 Machine purchase | Medium |
| 21+ | Late Game | Machines take priority; Dropper still worth buying | Diminishing |
🔧 Machines – All Types Explained
Machines are passive multipliers purchased with in-game cash. Unlike Dropper upgrades (which increase raw generation speed), Machines multiply the value of each EXP unit or explosion. A single well-timed Machine purchase can double your effective cash-per-launch — making Machine timing as important as Dropper investment.
Key insight: Machines stack multiplicatively. If you have two machines each providing 2x, your total multiplier is 4x — not 3x. This means stacking multiple S-tier Machines is exponentially more powerful than a single high-tier Machine.

Best Machine Build by Phase
| Phase | Priority Machine | Tier | Reason |
|---|---|---|---|
| Early (0–1 Rebirth) | Offline Collector | A | Maximizes idle time from day one — compound gains start immediately |
| Early-Mid | Blast Amplifier | S | Cash multiplier compounds with every future launch and upgrade |
| Mid (1–3 Rebirths) | Basic Dropper Mk.2 | S | Extends Dropper speed past the base upgrade ceiling |
| Mid-Late | Yield Booster | A | Raises EXP cap — unlocks higher nuke tiers and more cash per launch |
| Late (3+ Rebirths) | City Scanner | B | Identifies bonus explosion zones; situationally valuable at max progression |
💰 Cash Management Strategy
Cash management is one of the most overlooked aspects of Nuke Your City progression. The game's economy rewards aggressive reinvestment. Every second cash sits in your wallet instead of funding an upgrade is wasted compound interest.
Never hoard
Spend cash on upgrades the moment you can afford the next tier. Idle cash produces nothing.
Emergency buffer
Keep a small cash reserve only if you're close to affording a new Machine tier. Otherwise spend immediately.
Dropper first
In early game (Dropper lv 1–5), every coin goes to Dropper. No exceptions. No cosmetics.
Alternate mid-game
After Dropper lv 10, alternate Machine purchases with Dropper upgrades at a 1:2 ratio (1 Machine per 2 Dropper levels).
⚠️ Common Upgrade Mistakes
❌ Buying cosmetic upgrades before any S-tier Machine — cosmetics have zero gameplay value.
❌ Purchasing a Machine before Dropper Level 5 — Dropper ROI is strictly better in early game.
❌ Skipping the Offline Collector if you're a casual player — it's your most compounding investment over time.
❌ Not stacking Machines — players who buy one Machine and stop are leaving 2–4x multipliers on the table.
❌ Spending cash on Rebirth run cosmetics — Machines reset on Rebirth, cosmetics persist but add no speed.

Nuke Your City Upgrades – FAQ
Can I sell Machines in Nuke Your City?
No. Machine purchases are permanent within a run. Choose your purchase order wisely — consult the tier list before spending cash.
What happens to Machines on Rebirth?
All Machines and Dropper levels reset on Rebirth. Research Upgrades and redeemed codes are the only things that persist.
Do Machines stack additively or multiplicatively?
Multiplicatively. Two machines with 2x effects each give 4x total output, not 3x. This makes stacking multiple S-tier machines extremely powerful.
What's the best first Machine to buy?
Blast Amplifier for active grinders. Offline Collector for casual players who won't be watching the screen for hours.
How many Machine slots are there?
Machine slots unlock as you progress and Rebirth. The total cap increases with each Rebirth cycle, rewarding long-term progression.
When should I stop upgrading the Dropper and focus on Machines?
After Dropper level 10, Machine multipliers typically outpace raw Dropper speed increases. Alternate: one Machine purchase per 2–3 Dropper levels in mid-game.
