After spending over 500 hours grinding through zombie hordes in 100 Waves Later, I’ve learned one crucial lesson: your weapon choice can make or break your run. I’ve been there – stuck on Wave 47 with a useless MP5 while my teammates are melting bosses with Plasma Shotguns. Trust me, it’s frustrating.
But here’s the good news: I’ve tested every single weapon in the current meta, spent countless Scrap upgrading the wrong guns (so you don’t have to), and figured out exactly which weapons will carry you to Wave 100 and beyond. This isn’t just another tier list – this is your roadmap to becoming a 100 Waves Later legend.
If you’re new to this Roblox survival sensation, let me break it down. 100 Waves Later throws you and your team into increasingly difficult zombie waves. Each wave brings deadlier enemies, tougher bosses, and more chaos. The beauty lies in the variety – you can choose from multiple classes, unlock devastating weapons, and customize your build with unique perks.
What makes this game special? Every run feels different. The weapon you get from the Mystery Box, the skills that pop up, and the class you choose all create unique experiences. But with 25+ weapons available, knowing which ones are worth your precious Scrap is absolutely crucial.
I’ll be honest – I was skeptical at first. “Just another zombie survival game,” I thought. But then something clicked during my third run. I finally pulled a Plasma Shotgun from the Mystery Box, and suddenly, waves that had been destroying me were melting before my eyes.
The adrenaline rush of surviving Wave 50 with just 2 HP left, the satisfaction of finally unlocking the Engineer class, and the camaraderie of reviving teammates during intense boss fights – that’s what keeps me coming back. Plus, the developers are constantly updating the game with new weapons and balance changes, keeping the meta fresh and exciting.
After extensive testing across hundreds of runs, here’s my definitive weapon rankings. I’ve considered damage output, scaling potential, ammo economy, and versatility in different situations.
These weapons will single-handedly carry you through the game. If you get one of these, lock it in immediately and start upgrading.
| Weapon | Why It’s S-Tier | Best For |
|---|---|---|
| Plasma Shotgun | The absolute king – massive spread, incredible damage, pierces through multiple zombies | Everything – crowd control AND boss melting |
| Auto Shotgun | Beginner-friendly with consistent DPS, forgiving fire rate | New players and consistent performance |
| Gatling Laser | Unmatched crowd control with continuous laser damage | Wave clearing when zombies get overwhelming |
| Incendiary Shotgun (Robux Exclusive) | Fire DOT melts bosses, similar damage to Plasma Shotgun | Boss-focused builds with Robux to spend |
Personal Tip: I’ve found that the Plasma Shotgun with Gun Damage, Pierce, and 2x Legendary Damage skills can literally solo waves up to 60. It’s that broken.
These weapons are strong contenders that can easily carry you through mid-game. They usually have one minor drawback compared to S-Tier.
| Weapon | Strengths | Weaknesses |
|---|---|---|
| Greatsword | Best melee weapon, hits multiple enemies, saves ammo | Slow swing speed can leave you vulnerable |
| Pump Shotgun | Free starter weapon, scales incredibly well | Requires more upgrades to match S-tier |
| Sniper Rifle | Insane single-target damage with pierce | Requires good positioning and aim |
| Plasma Sword | Fast melee attacks, great backup weapon | Slightly lower DPS than Greatsword |
| Minigun | Excellent fire rate, good mob control | No built-in pierce, requires skill investment |
Pro Strategy: I always keep a Greatsword as my secondary weapon. During waves 1-15, I’ll switch to melee to conserve ammo for the tougher waves ahead. This simple trick has saved me countless runs.
These weapons work well in specific scenarios or with particular builds. They’ll struggle in late-game without heavy investment.
My Experience: I actually made a Flamethrower build work once. With Fire & Explosive skills and 2x Legendary Damage, I carried my team to Wave 45. But honestly? It’s not worth the Scrap investment compared to just getting a shotgun.
These weapons need specific class synergies or heavy investment to be effective. Most players should avoid these unless they’re dedicated to a particular playstyle.
Save your Scrap – these weapons will actively hurt your runs. They have terrible scaling, poor ammo economy, or just don’t deal enough damage.
Your class choice is just as important as your weapon. After testing every class extensively, here’s how they rank:
My Favorite Combo: Engineer main class with Wastelander’s Perk 3 (50% double upgrade chance). This setup has carried me to Wave 85+ multiple times, and the turret DPS is absolutely insane for crowd control.
Here are the working codes I’ve personally verified as of January 2026:
Codes expire quickly, so redeem them ASAP! I update this list weekly.
The developers dropped a massive update on January 15, 2026 that shook up the meta:
These changes have made laser weapons more competitive, but shotguns still dominate the meta. If you were running a Plasma Laser build before, now’s the time to revisit it!
After countless hours of gameplay, here are my secret strategies that most guides don’t mention:
During waves 1-15, I switch to my melee weapon (Greatsword preferred) exclusively. This saves hundreds of ammo that I’ll desperately need during the intense waves 40+. It’s simple but incredibly effective.
Always save your Super Skills for boss waves (every 10th wave). I can’t tell you how many times I’ve seen teammates waste their supers on regular zombies, then have nothing for the boss. Trust me, those supers make boss fights 10x easier.
Here’s a controversial take: don’t immediately equip weapons from the Mystery Box. Test them in a safe wave first. I’ve lost so many runs by equipping an MP5 thinking it was good, only to realize it’s garbage when it matters.
For squad runs, I recommend:
This composition has never failed me for reaching Wave 100+.
Not sure what to upgrade first? Here’s my priority list based on thousands of runs:
A: The Plasma Shotgun is currently the best all-around weapon. It excels at both crowd control and boss damage, and with the right skills, it can carry you through the entire game.
A: Honestly? Not really necessary. The Incendiary Shotgun is great, but the Plasma Shotgun is free and performs almost as well. Save your Robux for other games or wait for better exclusive weapons.
A: You need weapons with pierce or AOE damage. Single-target weapons like pistols can’t handle the zombie density in late waves. I recommend any S-tier shotgun or the Gatling Laser.
A: Soldier is perfect for newcomers. It’s cheap (20,000 Scrap), provides gun damage bonuses, and has a straightforward playstyle that teaches the game mechanics.
A: Play as Scavenger for the Scrap farming bonus, and always complete daily challenges. Also, don’t waste Scrap on D-tier weapons – it’s better to save up for one S-tier weapon.
Look, I’ve been where you are – staring down Wave 50 with a terrible weapon, wondering if this game is even beatable. But with the right weapons, smart class choices, and these strategies I’ve shared, you can absolutely conquer 100 Waves Later.
The meta might change, new weapons might drop, and balance patches will shake things up. But the fundamentals I’ve taught you here – prioritizing shotguns, saving Scrap for S-tier weapons, and understanding class synergies – will always serve you well.
Now it’s your turn. Jump into a game, try out these strategies, and let me know in the comments which weapons are working for you. And hey, if you see me in-game (username: WaveSurvivor), don’t hesitate to say hi!
