2 working codes for 100 Waves Later: LAUNCH and XMAS. Both give Scrap and Loads, which you need to buy classes. XMAS dropped during the Christmas event and could expire soon. Redeem it first.
100 Waves Later (formerly Zombie RNG) is a wave-based survival game where you fight zombies with different classes and weapons. Scrap is the main currency for unlocking classes like Wastelander and Pathfinder. Codes save you hours of grinding.
All Working Codes
| Code | Reward | Status |
|---|---|---|
| XMAS | Scrap + Loads | ✅ Working |
| LAUNCH | Scrap + Loads | ✅ Working |
Redeem XMAS first. Holiday codes usually expire faster than launch codes. LAUNCH has been active since the game released and might stick around longer.
How to Redeem Codes
- Open 100 Waves Later on Roblox
- Click the cogwheel icon in the top-left corner
- Find the code text box
- Type or paste the code exactly (case-sensitive)
- Hit Submit
Codes are case-sensitive. XMAS works. xmas doesn't. Copy-paste to avoid typos.
Expired Codes
No expired codes yet. The game is new, so both launch codes are still active. I'll move codes here when they stop working.
What Scrap and Loads Do
Scrap is the main currency. You spend it on:
- Unlocking new classes (500-2000 Scrap each)
- Buying weapons between waves
- Upgrading perks
Loads are secondary currency for:
- Cosmetics
- Some premium items
- Special unlocks
Classes are the priority. Wastelander costs 1500 Scrap and is the best class in the game. Free Scrap from codes gets you there faster.
Best Classes to Buy First
If you're new and wondering what to spend your Scrap on:
| Class | Cost | Priority |
|---|---|---|
| Wastelander | 1500 | Buy first |
| Pathfinder | 1500 | Buy second |
| Engineer | Free (Day 7) | Login reward |
| Boxer | 1000 | Good for melee builds |
Wastelander is the meta. Extra weapon slots, more ammo, better scaling. The 100 Waves Later Tier List explains why it dominates.
Engineer is free if you login for 7 consecutive days. Don't spend Scrap on it.
Where to Find New Codes
Codes drop through:
- 100 Waves Later Discord - Fastest source
- Game updates on Roblox
- Developer Twitter/X announcements
- Milestone celebrations (player count, likes)
The Discord is the most reliable. Devs post codes there before anywhere else. I check it daily and update this page when new codes drop.
Code Tips
Redeem immediately. 100 Waves Later codes expire without warning. The XMAS code could disappear any day now that the holiday is over.
One redemption per account. Each code works once. If you get an error saying "already redeemed," you've used it before.
Check spelling. Most "code not working" issues are typos. LAUNCH not Launch not launch.
Earning Scrap Without Codes
Codes give a nice boost, but most Scrap comes from gameplay:
- Surviving waves - More waves = more Scrap
- Killing zombies - Each kill drops small amounts
- Boss waves - Big Scrap payouts every 10 waves
- Daily rewards - Login bonuses include Scrap
The best Scrap farming is just playing well. Reach wave 50+ consistently and you'll have enough for all classes within a few days.
Starter Tips
Pick Wastelander or Pathfinder first. The starting class (Survivor) is weak. Save your Scrap for a meta class instead of spreading it across multiple unlocks.
Don't buy weapons early. Weapons drop from waves. Spend Scrap on classes and perks, not the weapon shop.
Play with teammates. Co-op gives more Scrap per run than solo. Classes synergize too, so a Wastelander + Engineer combo clears waves faster.
Focus on shotguns. Incendiary Shotgun and Plasma Pump Shotgun are the best weapons. The 100 Waves Later Guide covers weapon strategies.
