How to Top Up Z Day: Hearts of Heroes

Updated October 2026

Short answer: You can top up Z Day two ways. Buy packs in the in-game store with your Apple or Google account, or order the same pack through Packsify. Packsify buys the pack you pick through the official Apple or Google store, and you see every step in the app. You usually get 10 to 30% more pack value for the same budget, depending on the game, your currency and how you pay.

Below you get what Z Day players buy, both routes step by step, a price table, and when to time your purchases so each pack does more.

What Z Day players buy

In Z Day, the store runs on packs and bundles, with Gold as the premium currency they deliver alongside VIP points, hero fragments, speedups and gear materials.

• Hero fragments: Event chains, crates and value packs with fragments for new and existing heroes.
• HQ and research: VIP progression, the second builder and speedups for HQ and the Research Lab.
• Gear and the Destroyer: The Equipment Workshop, the Destroyer program and its Supersoldier Lab.
• Auction House: Design fragments open with bids in the thousands of Gold.

Packsify buys the packs you pick. A pack bought in the in-game store and the same pack bought through Packsify are exactly the same in your game.

We can buy almost every pack in your store, event packs included. A few monthly passes can't be bought, and we tell you before you pay.

What you pay with Packsify

Example: the $99.99 Z Day pack. Every game page shows the price for any pack you pick.

Route A: top up in the Z Day store

1. Open Z Day and go to the store.
2. Pick the pack you want.
3. Pay with the Apple or Google account on your device.
4. You get the pack right away.

This is simple and safe. You pay the store price.

Route B: top up Z Day through Packsify

1. Sign up in the Packsify app. If the game supports binding, bind your game account first.
2. Load credits in your own currency. Pay by card, Apple Pay, Google Pay, bank transfer, Revolut or USDT/USDC. Revolut and USDT/USDC have no processing fee. The minimum cart is 500 credits.
3. Pick the pack tier and send a clear screenshot of the exact pack. It shows our team exactly which pack to buy.
4. We buy that exact pack for you through the official Apple or Google store.
5. Follow every step live in the app, until your order is done.

When to buy: before the event, not during it

The biggest gain in Z Day spending is timing. The same pack bought for an event window does more than the same pack bought mid-week.

• Region vs Region and the Northern Front: Healing, training and speedups spike. Be ready before the front opens.
• Hero event chains and crates: Fragment chances expire with the calendar. Be ready to finish the hero inside the window.
• Auction House windows: Rare designs show up when they show up. Bids go to players holding Gold at that moment.
• HQ and research pushes: Line up a big push with an event that scores development.
• Monthly card and VIP: Keep both running so nothing lapses.

How a Packsify order stays safe

Every pack is bought through the official Apple App Store or Google Play, the same path you use on your own device. From the game side it looks like any standard purchase, because that is what it is.

Your recovery email and phone stay untouched, and you can follow every step of your order in the app.

Packsify has done this since 2021, with a 0 bans record and 4.9 on Trustpilot. Read the details in how we keep accounts safe.
