Survive The Swarm Combat Stats: Attribute Labels and Bonus Sources Explained

Survive The Swarm currently shows these combat attribute labels: Damage, Attack speed and Knockback as permanent pet buffs, and Attack speed, Crit chance, Crit damage and Attack count as in-run upgrade picks. What each field means numerically — exact units, formulas and stacking rules for every attribute — remains unknown.

Attribute labels observed in gameplay upgrade choices

In-run upgrade picks name combat attributes directly. One player picks attack speed, chooses crit chance and crit damage upgrades, and takes "plus one attack count" for a boomerang weapon. The named upgrade labels seen in play are:

• Attack speed
• Crit chance
• Crit damage
• Attack count

These labels confirm which attributes the game exposes, but observed play does not state the values, units or formulas behind any of them. Treat an upgrade pick as a confirmed label; treat its measured effect as unmeasured until you observe it yourself in a run.

Pet buffs: damage, attack speed and knockback

Essences are spent on eggs, and hatching them yields pets that carry permanent buffs. A third-party guide describes these buff types as damage, attack speed, or knockback. That description names the bonus fields on pets but does not define what each field does numerically — no units, percentages or stacking details are given. Two boundaries follow from this:

• Knockback is reported as a pet buff type. Whether it also appears on equipment is not established.
• Pet bonuses are permanent, but how they scale or stack with in-run upgrades and equipment is unknown.

What is confirmed and what stays unknown

Area deserves a specific note: nothing currently documents an Area attribute in Survive The Swarm, so its existence as a stat field is unconfirmed. Do not assume an Area value or effect exists until the game or reliable documentation shows one.

Using these labels on weapon and pet records

When you read a weapon or pet record, separate three things: the label (the field name, e.g. attack speed), the value shown next to it, and the demonstrated effect (what the bonus actually does in a run). Only the label is confirmed for every attribute listed above. If two records or two runs show the same label with different outcomes, compare them in-game rather than assuming a shared formula — the stacking and scaling rules behind the numbers have not been documented.

Return to any weapon, passive or pet record with this in mind: the field name tells you which attribute is being modified, but the size and stacking of that modification can only be judged from your own observations in a run.
