The best upgrades to buy first in VOID/BREAKER are the permanent hacks that feed the stagger loop, above all the one that cuts your grenade cooldown, followed by the hacks that hand you mods at the start of a run and the Recycler. During a run, grab slot-boosting modules like resonators and repeaters whenever you see them, because they multiply every other mod in your build.
VOID/BREAKER has two kinds of upgrades, and mixing them up is the most common early mistake. Below is how each works, the hacks to prioritize, the in-run mods worth chasing, and the old recommendations that no longer apply.
The Two Kinds of Upgrades
| Upgrade | Where you get it | Lasts |
|---|---|---|
| Hacks | Bought between runs at the hacks terminal in your base, with Voidium | Permanently |
| Modules (mods) | Found, bought or rewarded during a run | Until the run ends |
Hacks are your permanent progression. The game introduces the hacks terminal with a tutorial pop-up after your first death. You pay for tiers with Voidium, and decrypting a new hack with Decryptors unlocks its first tier automatically, per the HARD RESET update. Three hacks have started unlocked by default since the September 2025 patch, which Stubby Games added to ease early difficulty.
Modules are the run-by-run build. They come in categories (weapon, passive, ability, fire mode, melee and utility mods) and rarities from common up to legendary, plus risky corrupted mods. You place them on a grid, where some mods boost the slots around them.
Hacks to Buy First
Exact hack names and tier costs have shifted over Early Access, so here is what to prioritize by effect:
- Grenade cooldown. Our first pick. Grenades stagger enemies and staggered kills drop health and ammo, so a shorter cooldown feeds the loop that keeps you alive.
- Starting chests. One permanent upgrade places Optic and Mod chests at the start of each run, and a supply crate hack now gives an item chest. Stubby Games made the supply crate “more useful” in April 2026 by swapping its useless early ammo and health for an item chest. Starting with mods makes the first zone far smoother.
- Recycler. Added in the RECALIBRATION update, the Recycler hack makes a Recycler appear in shops so you can turn unwanted mods into credits. Higher tiers return more currency.
After those, spread Voidium across whatever helps your preferred weapon and playstyle. Higher difficulties pay more Voidium, so once runs feel comfortable, raising the difficulty speeds up the rest of your hack upgrades.
Old Hacks You Will Not Find Anymore
If you read advice from 2025, some of it points to hacks that are gone:
- Voidmax (Voidium drop rate), removed in February 2026
- Schematic Hyperdrive, removed in February 2026
- Severance, removed in April 2026, once melee damage started scaling with enemy health on its own
The economy changed around them, too: shops can now be rerolled with Voidium, and the last enemy in an area clear drops Voidium.
Mods to Grab During a Run
Your mods matter more than any single hack. These stand out:
- Slot boosters. Resonators, repeaters and invokers strengthen the mods around them. Stubby Games made the Corner Resonator epic rarity in September 2025 because “it’s just too good.”
- Critical Overdrive (ability): all damage is critical for a short duration.
- Ice Breaker (passive): enemies inflicted with ice always take a critical hit.
- Catalyst Adapter (ability): for a short time, every attack that can apply an elemental stack does.
- Armour Plate: blocks one hit, then is used up.
- Jump Stack: an extra jump, which pairs well with wallrunning builds.
- Zeus Strike (passive): enemies hit by tethered objects are struck by lightning.
Projectile mods like Homing Bullets and Chain Reaction, which ricochets projectiles to the closest target, appear in the official screenshots. Corrupted mods such as TheFloorIsLava, which raises weapon damage but hurts you while you touch the floor, are high risk and high reward.
How to Stretch Your Currency
- Research schematics. New mods only enter your loot pool after you find and research their schematics, and since February 2026 they are easier to spot with a UI and audio cue.
- Recycle, then reroll. Turn mods you do not need into credits at the Recycler, and reroll shops with Voidium when the stock is bad.
- Spend every run. Hacks are permanent, so there is no reason to bank Voidium.
