Cash, Tokens & Boosters

Cash sources, Hacker Tokens, boosters, and the official passes.

Updated

Exclusive Shop with cash packs and codes
The Exclusive Shop carries passes, cash packs, and the community codes box.

Cash is the main currency

Cash buys parts, vehicles, and skill nodes. It is earned during runs from two confirmed taps: killing zombies and covering distance, which the official 2x Cash pass description spells out ("Works both cash earned by killing zombies and distance travelling").

The HUD shows cash next to a second green token counter at the bottom-left of the screen. Codes commonly grant cash — CashDrop gives 500 and COMMUNITY hands out 1,000 alongside starter parts.

Hacker Tokens

Hacker Tokens are the limited event currency attached to the September 2026 Hacker Event. Two of the five current codes grant them (HACKER: 50; 1x1x1x1: 150).

Because they are event-scoped, their long-term value is the event's shop contents; this page tracks the token balance sources and will expand once the event spending options are documented.

Boosters and bonuses

A Global Booster panel appears in the world showing a 10K booster with a reset countdown, and the bottom-right of the HUD carries small bonus meters (+0% when inactive). Boosters appear to be timed server-wide multipliers that reset on a cycle.

Stacking those windows with a good build is the free-to-play answer to the paid luck passes: roll during a booster, then spend the results on a longer run.

Official game passes

Four passes exist on the official page, and each one targets the loop directly. Their store descriptions are quoted below as published.

The Exclusive Shop

In-game, the Exclusive Shop screen carries the pass listings alongside cash packs and a Gift A Player button, plus the Community Codes box. Cash packs observed in the shop are bundles like 50K and 100K with Robux price buttons.

A 60% Off Gamepass promotion was listed in a September what's-new panel, which is the pattern to watch if you are considering a pass: discounts have appeared alongside content updates.

FAQ

Cash, Tokens & Boosters FAQ

What is the fastest way to earn cash?

Runs that go deep — distance and kills both pay. Stack that with the 2x Cash pass or a global booster window if you have them.

Are Hacker Tokens worth collecting?

They are the event currency, and two current codes grant them for free. If you play during the event window, redeeming both codes is a no-risk way to bank them.

Were game passes ever discounted?

Yes — a what's-new panel in September 2026 advertised 60% off Gamepass, so sales do happen around updates.
