Into the Dark builds its entire seasonal loop around a single resource and the modifiers it powers. The Hyenas have refined their Potent Spice formula using a chemical compound pulled from the Dark Zone, and your job is to recover Sample Cannisters from their operations before those materials cycle back into production. Those cannisters feed every modifier layer in Year 8 Season 2, from passive buffs that scale across the season to combat-only effects you trigger on the fly.
Quick answer: Y8S2 runs one Global modifier (Cleaning up the Streets), three Active modifiers (Invincible, Pneuma, Vicarious), nine Passive modifiers split across Gadgets, Resistances, and Offensive with only three slottable at once, and three Hostile modifiers (Folie à Deux, Plague Doctor, Soporific). Sample Cannisters power the Global bonuses and Surge versions of the Active modifiers.
Cleaning up the Streets Global modifier and Sample Cannisters
The Global modifier for the season is Cleaning up the Streets. It centers on Sample Cannisters, a new seasonal resource tied directly to Hyena activity. You collect them, then deny the Hyenas the chemical compounds they need to keep making Potent Spice.
Sample Cannisters drop from several sources, with the Toxic Dark Zone serving as the most reliable hunting ground. The drop reliability changes by source, so plan your farming around Landmark chests first.
| Source | Drop reliability |
|---|---|
| Toxic Dark Zone Landmark chests | Guaranteed large amount |
| Toxic Dark Zone material chests | Guaranteed medium amount |
| Hyena enemies inside the Toxic Dark Zone | Medium chance |
| Hyena enemies in missions outside the zone | Small chance |
| Other enemy factions | Greatly reduced chance |
You can carry a limited number of Sample Cannisters at once. That cap can be raised by equipping a specific Passive modifier, which matters during long Toxic Dark Zone runs where you want to bank as many as possible before leaving.
Cannisters have two uses. You contribute them at the seasonal vendor, located in the Base of Operations next to the Specialization table, to raise the Sample Size bar and unlock stronger High-Quality Munitions bonuses. They are also consumed automatically when you trigger a Surged version of an Active modifier.

High-Quality Munitions is the temporary combat buff you receive after contributing Sample Cannisters at the seasonal vendor. As the Sample Size bar fills across the season, each new level adds another bonus on top of everything already unlocked, so the buff grows more powerful over time.
| Sample Size level | Bonus added |
|---|---|
| Starting | +50% Optimal Range |
| Level 1 | +50% Weapon Handling |
| Level 2 | +50% Magazine Size |
| Level 3 | +50% Damage to Armor |
| Level 4 | +50% Rate of Fire |
The buff runs on a stack system. Each Sample Cannister you add at the vendor grants 5 High-Quality Munitions stacks, and every unlocked bonus stays active while at least one stack remains. Stacks only drain on a manual reload or an automatic reload from an empty magazine. Effects that top off ammo without emptying the magazine leave your stacks untouched, so large-magazine builds stretch each stack further.
Active modifiers and the Surge mechanic
Three Active modifiers anchor the season, each with a base effect, an upgraded Surge version, and level-based upgrades. Surge fires automatically when you activate the modifier and hold enough Sample Cannisters in your inventory, spending them to strengthen the effect. Inside the Toxic Dark Zone, every Surged activation also lowers your Toxicity, which makes Surge a dual-purpose tool for both power and survival. All three run a 180-second cooldown.
| Active modifier | Base effect | Surge additions |
|---|---|---|
| Invincible | Fully heals you, repairs armor, and grants very high damage reduction. Damage taken is stored and dealt back when the effect ends. While enemies are in front, it adds +20% Movement Speed, +5% Armor on Kill, and +25% Damage to Targets Out of Cover. | +10% Armor on Kill, +50% Damage to Targets Out of Cover, reduced stored damage on expiry, and Bonus Armor that lasts 20 extra seconds. |
| Pneuma | Increases Weapon Swap Speed. Kills build Inhale (MMRs/Rifles/Pistols: +5% Headshot Damage, +2.5% Accuracy), Hold (ARs/LMGs: +1% Crit Chance, +2.5% Stability), and Exhale (Shotguns/SMGs: +2% Crit Damage, +2.5% Reload Speed) stacks that all apply to every weapon. | Higher stack caps, plus extra stacks from headshot kills (Inhale), kills within 5 seconds of a prior kill (Hold), and close-range kills (Exhale). |
| Vicarious | On activation, counts nearby allies and enemies, then grants increased Skill Efficiency, makes enemies in radius take more Skill Damage, and boosts Repairs and Healing for allies in radius. Strength scales with how many are present. | Further increases Skill Efficiency and extends the effect to allies and enemies around your active skills, widening coverage when skills are placed well. |
Each Active modifier also has its own upgrade path. Level 2 improves a core trait such as a shorter cooldown (Invincible), longer duration (Pneuma), or a larger effect radius (Vicarious), while Level 3 reduces the Surge cost on all three.
Passive modifiers: three categories, three slots
There are nine Passive modifiers, divided into Gadgets, Resistances, and Offensive categories. You can only run three at a time, so build choices matter. They support the season’s core systems rather than acting as standalone power spikes.
- Reduce the Surge cost of Active modifiers.
- Improve resistance to Toxicity and Status Effects inside the Toxic Dark Zone.
- Increase how many Sample Cannisters and High-Quality Munitions you can carry.
- Add new ways to debuff enemies.
If you plan to farm the Toxic Dark Zone for extended stretches, the Resistances passives that blunt Toxicity buildup pair naturally with a carry-capacity passive, letting you bank more cannisters before the meter forces you out.

Hostile modifiers and how they raise Toxicity
Three Hostile modifiers strengthen enemies and pressure your squad, and each one interacts with Toxicity when it appears inside the Toxic Dark Zone. Leaving these enemies alive is one of the fastest ways to spike the meter, so they shape how you prioritize targets.
| Hostile modifier | Effect | Toxic Dark Zone interaction |
|---|---|---|
| Folie à Deux | A timer starts when the enemy first takes or deals damage, and its damage climbs over time. If it survives past that timer, the modifier can jump to a nearby enemy on death. | Raises Toxicity for nearby agents. |
| Plague Doctor | Grants health regeneration to nearby enemies of the same faction. | Agents within its radius gain Toxicity over time. |
| Soporific | Applies the Lethargy debuff on hit, which gives your incoming damage a chance to inflict Disorient. Killing the enemy removes the debuff regardless of time left. | Toxicity rises each time Soporific triggers Disorient on you. |
Inside the Toxic Dark Zone, Toxicity is a constant pressure that builds the longer you stay. To bring it down, trigger a Surged Active modifier, step into a safe house or checkpoint to freeze and clear it, or leave the zone entirely to wipe it out. Prioritizing Plague Doctor enemies early keeps the meter from running away during drawn-out fights, while banking Surge charges gives you an on-demand way to cut Toxicity when it climbs too high.
