You're grinding. It's late. You finally have enough resources to start looking at that drone bay, and then it hits you: the sheer wall of jargon. Last war drone components aren't just another loot drop you can ignore until the endgame. If you've spent any time in the apocalyptic trenches of the Last War: Survival mobile game, you know that drones are basically your "get out of jail free" card for high-level PvE and the difference between winning a duel or getting zeroed in a heartbeat.
Honestly, most players treat drones as an afterthought. They focus on the heroes, the tank tiers, and the research tech. Big mistake.

A drone is a force multiplier. But it’s a picky one. If you don’t understand the distinction between a blueprint and a microchip, or why you’re suddenly hitting a progression wall at level 20, you’re wasting time. Let's get into what actually makes these things tick.
What Last War Drone Components Actually Do (And Why You Need So Many)
The drone system in Last War is a resource sink. There is no way around that. But it's a sink that pays dividends.
Basically, your drone is an extra "unit" on the field that provides passive buffs to your entire squad and active damage during combat. The components are the raw materials required to upgrade the drone's level and its specific attributes. Think of them like the "gear" your drone wears. You have the Drone Parts, which are the bread and butter of your leveling process. These are the grey, blue, and purple gear pieces you see piling up in your inventory.
Then there are the Drone Data Chips.
These are different. While parts give you raw stats like Attack, Defense, and HP, the data chips are what you use to actually level up the drone’s core. Most people get confused here because the game uses similar icons for both. You need the data to raise the level cap, and you need the components to fill out the slots that make those levels meaningful.
The Component Tier System
It’s not just about having "some" parts. It’s about the color.
- Grey (Common)
- Green (Uncommon)
- Blue (Rare)
- Purple (Epic)
- Gold (Legendary)
You’ve probably noticed that the jump from Blue to Purple feels like a marathon. That’s intentional. The developers at FirstFun designed the economy to slow you down right as your base hits the mid-game (around Level 15-19). You need multiple lower-tier components to fuse into a single higher-tier one. It’s a classic merge mechanic hidden inside a strategy game.
Where Everyone Messes Up the Drone Tech Tree
Here is the truth: most players spread their components too thin.
They try to balance everything. They want a little bit of attack, a little bit of armor, and a little bit of health. In Last War, specialization usually wins. If you are running a tank-heavy lineup (which most people do because of heroes like Murphy and Williams), you want your drone components to lean heavily into Attack. Why? Because your heroes are already soaking up the damage. The drone needs to be the glass cannon that helps clear the backline.
If you’re pouring your hard-earned last war drone components into defensive stats while your frontline is already holding, you’re essentially slowing down your clear speed.
The Hidden Power of Drone Skill Chips
Beyond the basic components, you’ve got the skill chips. These are the "active" parts of the drone. You’ve got things like the Laser Cannon or the Healing Mist.
A lot of guys in the top alliances will tell you that the Laser is the only thing that matters. They aren't entirely wrong, but they're ignoring the nuance of the "Arms Race" event. During the Arms Race, specific drone upgrades give you massive points toward those daily chests. If you dump all your components on a Tuesday but the Drone objective doesn't hit until Thursday, you’ve just sabotaged your own growth.
Patience is a component in itself.

You don’t have to be a whale to have a decent drone. You just have to be annoying about your daily tasks.

The Drone Center is your primary source. You should be checking this constantly. But the real meat is in the Alliance Store and the Honor Store. If you are in an active alliance—and if you aren't, leave yours right now and find one that actually does the Rally events—you should be swimming in Alliance Credits. Use these for drone parts. Every single day. No excuses.
- Radar Tasks: These are easy wins. Do the ones that specifically list drone components as a reward first.
- The Secret Task Agency: Always refresh your tasks until you see at least a Purple-tier reward for drone data or parts. It costs a few gems, but the ROI is better than almost anything else in the game.
- Zombie Invasion Events: This is where the big hauls happen. If your alliance coordinates well, you can walk away with enough components to jump two or three levels in a single afternoon.
Don't forget the Daily Sale tab. Sometimes there are "free" or heavily discounted components hiding under the "Hot Deals" that aren't actually hot, but the drone stuff is usually worth the 100-200 gems if you're close to an upgrade.
The Math of Merging: Is It Worth It?
Let's talk about the merge. To get a Gold (Legendary) component, you need a staggering amount of Grey parts.
It takes four of one tier to make one of the next.
4 Greys = 1 Green.
16 Greys = 1 Blue.
64 Greys = 1 Purple.
256 Greys = 1 Gold.
When you see it laid out like that, it looks impossible. It's not. But it does mean you shouldn't be "Quick Equipping" everything the second you get it. You need to look at your total inventory. Sometimes it’s better to keep four Purple components equipped across your drone's slots than to merge them into one Gold and leave three slots empty or filled with Greys.
The total stat bonus from four Purples often outweighs the single-slot bonus of one Gold. You have to do the math on your specific stats page. Look at the "Total Power" change before you commit to a high-level merge.
Combat Effectiveness: The Drone in Action
In a battle, the drone behaves differently depending on the components you've prioritized. If you’ve focused on the Attack Speed components, you’ll see those red tracers flying much more frequently. This is huge for breaking through "Shield" buffs on enemy heroes.
Conversely, if you’re struggling against the World Boss or the "Cerberus" style encounters, you might think you need more health components. You don't. You need more Critical Hit components. The drone's crit rate is separate from your heroes, and because the drone attacks so rapidly, a high crit rate leads to massive DPS spikes that can help you clear those last few bars of boss health before the timer runs out.
The "Arms Race" Strategy
Since last war drone components are so vital for event points, save your "Drone Component Chests" in your backpack.
Do not open them when you get them.
Wait for the "Drone Empowerment" stage of the weekly or daily events. Opening 50 chests at once when there's a 2x point multiplier active will catapult you to the top of the rankings, giving you even more components as a ranking reward. It’s a feedback loop. Use it.

Actionable Insights for Your Drone Build
Stop clicking "Auto-Upgrade" and start playing the long game. Your drone is the only unit that doesn't "die" or need healing after a battle. It is the most consistent part of your power score.
Prioritize these steps immediately:
- Check your Secret Task Agency: Refresh for Purple or Gold drone tasks only. This is the most efficient use of your stamina and time.
- Hoard your chests: Only open Drone Component Chests during the "Drone Development" phase of the Arms Race or Alliance Duel.
- Focus on Attack first: In the current meta, a drone that kills faster is better than a drone that survives longer. Upgrade the top-left and top-right component slots first.
- Join a Top 10 Alliance: If your alliance isn't hitting the high-level zombie rallies, you are missing out on roughly 40% of the potential free components available per week.
- Watch the Fuse: Never merge your only set of high-tier components if it leaves the rest of your drone's slots empty. Keep the balance until you have enough "trash" parts to fill the gaps.
The drone is a marathon, not a sprint. You’ll see the biggest gains once you hit the Level 25 mark on the drone itself, as that’s when the component multipliers really start to kick in and change your total squad power by the millions. Stay consistent with your daily buys in the Alliance store, and you'll stop being the person getting raided and start being the one doing the raiding.
