Destroy other tanks
The official description says it directly: destroy tanks and earn gems. This is the core gem engine — fight once your bullets reliably win trades, farm food until then.
Gems
Gems are earned, not bought.
The official loop is blunt: destroy tanks and earn gems. Two official codes hand you 75,000 for free, and — confirmed against the public catalog on August 20, 2026 — there is no priced gamepass selling you a shortcut.
Quick start
Three ways gems reach your wallet.
All verified against the official page and catalog on August 20, 2026.
Redeem the two gem codes
NEWCURRENCY grants +50,000 gems and HEADSTART grants +25,000 gems, exactly as printed on the official page. Redeem them from the lobby — steps on the codes page.
Join the 7x3 group (free, optional)
The developer group's description is "Group for perks, benefits and community!" and guides point members to exclusive in-game upgrades. Exact current perks are not specified on the group page — joining is free, so check in-game.
The big picture
Two progress tracks: XP and gems.
The four official codes map perfectly onto the game's two economies — understanding that split explains most of progression.
| Track | Feeds | Codes that boost it |
|---|---|---|
| XP | Levels → stat points in the E menu | REBALANCEAGAIN +250,000 XP · HAVEFUN +200,000 XP |
| Gems | The gem economy tied to destroying tanks | NEWCURRENCY +50,000 gems · HEADSTART +25,000 gems |
A naming note: official text says "gems". Some community wikis call the shop currency "Diamonds" — whether those are one currency or two is not proven from official copy. Trust the in-game labels (checked August 20, 2026).
What gems buy: secondary guides describe shop unlocks and stat-cap raises, but the details are dated and disputed. Read the current shop in-game rather than any archived price list.
Robux check
There is nothing to buy.
Confirmed against the official game-pass catalog on August 20, 2026.
One pass exists — offsale
The catalog lists a single pass named hello, marked offsale with no price. It is not purchasable, and trackers show the same status.
No VIP, no paid Titan
No priced VIP or pay-to-win pass was listed at this check. Ignore older articles quoting prices for premium tanks — treat the live catalog as the truth.
Gems FAQ
Gem questions, answered.
Earning, spending, and the currency name confusion.
What is the fastest way to earn gems?
Redeem NEWCURRENCY and HEADSTART for 75,000 free gems, then destroy other tanks once your build wins trades. Until it does, food farming levels you toward builds that can fight — see the stats page.
Are gems and Diamonds the same thing?
Unproven. Official copy says gems; some community wikis say Diamonds for the shop currency. The in-game label is the authority — checked August 20, 2026.
Can I buy gems with Robux?
Not through a gamepass — the public catalog showed only an offsale pass named hello at this check. If the shop ever sells currency directly, the in-game store will say so.
What should I spend gems on first?
We do not print a shopping list: shop contents and prices are mutable and current guides disagree. Decide inside the game, after your class path is set.
75,000 free gems are waiting.
Grab the codes, then build a tank worth spending them on.
