Understanding Scraps: The Economy of 100 Waves Later

To get more Scraps, you first need to understand how the game’s economy works. Scraps aren’t just dropped randomly; they are tied to your performance in combat. In 100 Waves Later, efficiency is key.

You earn Scraps primarily by:

Completing Waves: Every wave cleared grants a base amount of Scraps.
Killing Enemies: The majority of your income comes from the bounties on enemy heads.
Bonus Objectives: Some maps or special events offer hidden bonuses for clearing waves without taking damage or clearing within a specific time.

My experience has taught me that simply “surviving” isn’t enough. You need to dominate. The faster you kill enemies, the faster the wave ends, and the quicker you move to the next payout. Time is money, quite literally, in this game.

Top Strategies to Farm Scraps Fast

Now, let’s get into the meat of the guide. These are the specific strategies I use to maximize my Scrap intake.

1. The “Speed Run” Strategy for Early Game

When you are starting out, you don’t have the high-damage units needed to AFK (Away From Keyboard) farm. You need to be active.

Focus on Single-Target DPS: In the early waves (1-20), enemies have relatively low health but come in moderate numbers. Don’t waste your Scraps on expensive AOE (Area of Effect) towers yet. Invest in one or two high-damage ground units.
Placement Matters: Don’t just place units randomly. Look for chokepoints—narrow areas on the map where enemies are forced to cluster. Placing your damage dealers here ensures they are constantly firing, maximizing kill efficiency.
Re-deploy Aggressively: If a unit isn’t attacking, move it. I constantly check my field. If a lane is clear, I pick up my tower and move it to the next active lane. This keeps your DPS (Damage Per Second) utilization at 100%.

2. The “Chokepoint Hold” Strategy for Mid-Game (Waves 21-50)

As you progress, enemies get tougher. The single-target strategy starts to falter. This is where AOE becomes your best friend.

Invest in Splash Damage Units: Start saving your Scraps to unlock units that deal splash damage. These units can hit multiple enemies at once, effectively multiplying your Scrap income per shot.
Create Kill Zones: Use your cheaper units to block or slow down enemies at a specific point. Then, pile all your AOE units behind that blockade. This creates a “kill zone” where enemies die instantly, giving you their Scraps immediately.
Upgrade Wisely: Don’t spread your Scraps thin. It is better to have one fully upgraded Mythic unit than five Level 1 Rare units. Focus your resources on your strongest carries.

3. The “Economy Unit” Strategy (Advanced)

Many players overlook the power of economy units in favor of pure damage. This is a mistake. In 100 Waves Later, having a unit that generates Scraps passively or buffs your Scrap drop rate can change the game.

Scrap Generators: If the game has a specific unit type that generates resources (often called “Farmers” or “Miners”), place them as early as possible. Even if they deal no damage, the long-term investment pays off massively by Wave 40+.
Buffs: Check the unit descriptions. Some units provide a buff that increases the amount of Scraps dropped by enemies. Pair these units with your strongest damage dealers to maximize the return on every kill.

4. AFK Farming: Is It Worth It?

Eventually, you will unlock units so powerful that you can leave the game running and they will clear waves for you. This is AFK Farming.

Pros: You can earn Scraps while you sleep, go to school, or do other things.
Cons: It is often slower than active grinding, and if your defense breaks, you lose the momentum (and potentially the rewards if the game has strict penalty mechanics).
My Recommendation: Only AFK farm if you have a setup that can clear waves instantly. If it takes 10 minutes to clear one wave, you are better off actively playing a lower difficulty map for faster, repetitive Scraps.

Utilizing Codes and Daily Rewards

One of the easiest ways to get a boost in Scraps is through Codes. The developers of 100 Waves Later frequently release codes that provide free Scraps, boosts, or units. Since these codes expire, you need to stay updated.

Based on my research and verification from official sources, here are the types of rewards you should look for:

Scap Multipliers: Codes that give a 2x Scrap boost for a limited time (e.g., 15-30 minutes). Pro Tip: Only activate these boosts when you are ready to grind intensely. Don’t use them while you are AFK farming slowly!
Flat Scrap Grants: Some codes give a lump sum of Scraps (e.g., 500 or 1000). Always claim these immediately.

Note: For the latest active codes, check the official Discord server or the game’s description page. Codes change monthly, so what worked in [last month] might not work in March 2026.

Game Passes: Are They Worth It?

As an experienced player, I am often asked if spending Robux on Game Passes is worth it for farming Scraps. Here is my honest take:

Scraps Multiplier Pass: If you plan to play this game long-term, this is usually a “Must Buy.” A permanent 1.5x or 2x Scraps multiplier adds up over hundreds of waves. It essentially pays for itself over time.
Auto-Collect Pass: In some games, you have to manually walk over to dropped Scraps to pick them up. If 100 Waves Later has this mechanic, an Auto-Collect pass is a game-changer. It ensures you never miss a drop, significantly increasing your income.
Unit Storage: More storage allows you to keep different team compositions. While it doesn’t give Scraps directly, having the right tool for the job (specific anti-air or anti-ground units) helps you clear waves faster, leading to more Scraps.

Common Mistakes to Avoid In 2026

Through my own trial and error, I’ve identified several common mistakes that prevent players from maximizing their Scraps. Avoid these to stay ahead of the curve:

Skipping Early Upgrades: Don’t save all your Scraps for a late-game unit that costs 10,000. A small investment in upgrading your current units can help you clear the current wave faster, unlocking the higher Scraps rewards sooner.
Ignoring Unit Synergy: Some units work better together. For example, a unit that freezes enemies pairs perfectly with a high-damage sniper. Using them together creates a synergy that clears waves more efficiently than using them separately.
Greed: Trying to push to a wave that is too hard for your current level usually results in a loss. You deal zero damage when dead, earning zero Scraps. It is better to farm a slightly lower wave that you can clear quickly and safely.

Advanced Tips for 2026

As the game updates in 2026, the meta evolves. Here are some advanced tips to keep you on top:

Watch the Update Logs: Developers often nerf “overpowered” farming strategies. If a specific unit is suddenly generating way too many Scraps, enjoy it while it lasts, but expect a change.
Join a Community: Joining the Official Discord Server or a subreddit for the game is invaluable. Players share the latest “meta” builds for farming Scraps. If a new unit is released that breaks the economy, you will hear about it there first.
Sell Strategically: Some games allow you to sell towers for a percentage of their value. In late waves, selling your AOE towers to buy a Boss killer (and then selling the Boss killer to buy back AOE) can be a smart strategy to handle diverse enemy types without losing Scrap value.

Troubleshooting Scrap Farming

Q: I’m killing enemies but not getting Scraps. Why?
A: This usually happens if you are too far away from the kill or if you are in a “Hardcore” mode where you need to manually collect the loot. Check the game rules and ensure you are close enough to the action.

Q: My progress feels too slow. What should I do?
A: Re-evaluate your team composition. If you are struggling on Wave 20, go back to Wave 10 and farm until your units are upgraded. Don’t try to force progress; let the power come to you through upgrades.

Q: Did the drop rates change in the latest update?
A: Game developers often tweak drop rates. If you notice a sudden change, check the official X/Twitter Account for patch notes. They might have adjusted the economy to balance new content.

FAQ’s

What is the fastest way to get Scraps in 100 Waves Later?

The fastest way is to use a Speed Run strategy on early waves with high DPS units. Combine this with an active Scrap boost code or multiplier Game Pass to maximize the gains from every kill.

Do codes give Scraps?

Yes, frequently. Codes usually provide either a flat amount of Scraps (e.g., 500 Scraps) or a temporary timed multiplier (e.g., 2x Scraps for 20 minutes).

What units should I use for farming?

For farming, prioritize Splash Damage (AOE) units to kill large groups of standard enemies quickly. In late-game, Economy Units (if available) or units with Scrap Drop Buffs are essential.

Can I farm Scraps AFK?

Yes, once you have strong enough units and a strategic placement (chokepoints), you can AFK farm. However, active manual grinding is often faster unless you have a very high-level setup.

How do I use the Scrap codes effectively?

Save your codes for when you have time to play actively. Do not redeem a 2x Scrap code and then go AFK. Use the code, then play the most difficult wave you can handle quickly and repeatedly for maximum profit.

Is it worth buying Scraps with Robux?

I generally recommend buying Game Passes that increase your earning rate rather than buying Scraps directly. Passes provide a permanent benefit that helps you throughout the entire game, whereas bought Scraps run out quickly.

Conclusion

Mastering the art of farming Scraps in 100 Waves Later is about more than just clicking buttons; it’s about strategy, efficiency, and smart resource management. By following the strategies outlined in this guide—using the Speed Run method for early game, optimizing your chokepoints for mid-game, and leveraging AFK farms and codes for late-game—you will see your Scrap balance skyrocket.

Remember, the meta changes, so stay updated with the community and keep experimenting with new unit combinations. Good luck, and I’ll see you on the leaderboard!
