Heavy machine gun!!!
Remember when you were 12, pumping quarters into that Metal Slug cabinet at the pizza shop? Hands covered in grease, Mountain Dew fizzing out of your nose, mashing buttons like your life depended on it? Remember That feeling? We are bringing it back. This is the first NFT collection from Metal Slug by SNK.

Memories
You remember the first time you saw Metal Slug. Maybe it was 1996 at the arcade. Maybe it was your cousin's basement. Maybe it was that sketchy pizza place where the bathrooms were questionable but the Metal Slug cabinet? Chef's kiss.
You died 47 times trying to beat the first level. Your mom was yelling at you to come home. You smelled like pepperoni and broken dreams. But you kept going because Metal Slug hit different.
RAWKET LAWNCHAIR
30 years later, Metal Slug still hits different. 10+ games. Millions of fans worldwide. Pixel art that makes grown adults weep. And now? Steel Hearts—the franchise's first official NFT collection AND first-ever webcomic adaptation.
This isn't some corporate cash grab. This is for the people who know what "RAWKET LAWNCHAIR" sounds like in their soul. The people who still hear that coin drop sound in their dreams. The people who unironically think the MetalSlug SV-001 tank is peak vehicle design.
STEEL HEARTS
Steel Hearts brings Metal Slug chaos into Web3 the right way: webcomic drops, community story voting, Proof of Reading rewards, $SLUG token airdrops, and eventually... upgradable vehicles you can flex harder than a Rocket Launcher pickup.
For 30 years, we dropped quarters and button-mashed. Now we drop ETH and build together. The arcade cabinet is calling you back. But this time? You're not just playing. You're part of the story.
This is for everyone who ever yelled "HEAVY MACHINE GUN" in public and didn't care who heard.
// PIXEL ART SO GOOD IT'LL MAKE YOU CRY
Every NFT in the Steel Hearts collection is hand-crafted pixel art that honors Metal Slug's legendary arcade aesthetic. You know that feeling when you saw Metal Slug animation for the first time and your brain was like "wait video games can look THIS good?"
That's what we're going for.
This isn't some AI-generated slop. This is real artists, real pixels, real love for the franchise. Every frame, every trait, every detail is a love letter to the arcade era when games were hard, quarters were currency, and graphics peaked at 320x224 resolution.
(Yeah thats the actual in game sprite from Level 1)

// QUESTIONS?
WE'VE GOT ANSWERS.
A: Yes, we worked with SNK Corporation, the Japanese video game company behind Metal Slug as well as other iconic franchises like The King of Fighters and Fatal Fury. This collection is produced from an official license from SNK Corporation.
A: Three things: (1) Metal Slug is 30 years of proven IP not some startup's first rodeo, (2) we're actually building—webcomic every Friday, Proof of Reading rewards, $SLUG airdrop at Day 90, vehicle upgrades at Month 6,(3) we're not pretending this is an "investment," it's a digital collectible for people who love Metal Slug and want to be part of something fun. Also we have good memes.
A: Nah. Metal Slug fans will catch all the references and easter eggs, but Steel Hearts is designed as a self-
contained story. If you've never played Metal Slug (first of all, go play it), you'll still understand and enjoy
the webcomic. Think of it as your entry point into 30 years of legendary gaming culture.
A: At Day 90 post-mint, every holder gets airdropped $SLUG tokens. It's the in-universe currency for Steel
Hearts. You'll use $SLUG to upgrade vehicles, buy exclusive merch, access special events, participate in
contests, and flex on people who paper-handed before the airdrop. Stack your $SLUG. Don't be that guy who sold
before Day 90 and rage-posted on Twitter about missing the drop.
A: All holder benefits transfer with the NFT—webcomic access, Proof of Reading eligibility, voting rights, $SLUG airdrop eligibility (if you're still holding at Day 90), and future vehicle upgrades. The new holder
immediately gains all benefits. However, your Proof of Reading progress (reading streak, card mining history)
stays with YOU, not the NFT.
A: Pro tip: mint when Americans are sleeping.Gas is cheaper. You're welcome.
A: Whitelist spots are distributed through Telegram campaigns, Twitter engagement contests, community contributions, and partnerships. Follow @Steel_HeartsNFT on Twitter and join our Telegram for current whitelist opportunities.
A: Yes! The mint function works on mobile. Use MetaMask Mobile, Rainbow, or Coinbase Wallet app and mintdirectly from your phone. Just don't do it while driving. Or operating heavy machinery. Or playing actual MetalSlug (you need both hands for that).
A: MORE TBA!
A: Everyone can read the first chapter. The rest is TBD!
A: Worst case? You own a piece of Metal Slug history — the first official NFT collection from a 30-year legendary franchise. That's still cool. That still has value. We're not promising you'll get rich. We're promising we'll show up for a good time. we'll airdrop $SLUG at Day 90, and we'll launch vehicle upgrades at Month 6.
We're building for the long haul. But also this is crypto and NFTs, so like, DYOR and only spend what you can afford to lose.
// JOIN THE BATTALION
