Spore Mine Tyranid Minoris

Enemy Stats

Model & Hitboxes

Summary of Tactics and Strategy

There are two mine types: the standard Spore Mine (direct pursuit kamikaze) and the Acid Mine (area-denial with acid shower). Both have 1 HP. Shoot them at range whenever possible. In melee, use knockback attacks (heavies, dashes, specials) to push the mine away before it detonates at a safe distance. Standard light combo attacks lack knockback and kill the mine in place, causing it to explode in your face. See the full melee weapon knockback table below.

Spore Mines detect players via vision and become alert at 20m, speeding up from 4.5 to 6.5 m/s. They use simple nearest-target selection (same as Hormagaunts) and orbit at 10-15m before attacking. Their close-range melee charge (faster, 1.2s total) only unlocks after being within 10m of you for 5 seconds, if you close quickly and use a knockback attack, you can swat them before the fast attack unlocks. Both mine types deal dmg_type_bioweapon_explosive on detonation and leave a toxic void zone (4m radius, 5.5s, 5 toxic stacks/sec), move out immediately after any explosion. Acid Mines are smarter: they use path-length targeting, can guard their parent Biovore in defensive mode, and cast an acid shower on death to create toxic zones.

Biovore Connection

Biovore-Launched Mine Projectiles

Biovores fire two types of mine projectiles:

Standard Mine Projectile (pjl_biovore_mine_server.cls):

• Homing, 1 HP, 5x melee sensitivity

• On direct hit: explodes immediately

• On landing: converts into a full Spore Mine NPC that independently pursues players

• Alternative: 3s timed fuse variant that detonates instead of converting

Acid Mine Projectile (pjl_biovore_acid_mine_server.cls):

• Inherits from standard mine projectile

• Archetype: TyrAcidMine, preset: Agressive

• On landing: becomes an Acid Mine NPC

Biovore Explosion Exclusion

Spore Mine explosions explicitly do not damage Biovores (archetypesNotToDealDamageTo = ["TyrBiovore"]).

Spore Mine Variants

Spore Mine

The basic kamikaze mine - flies toward the nearest player and detonates.

Acid Mine

A smarter mine with an acid shower ability and strategic positioning.

Acid Mine has two behavioral presets:

• Defensive - finds the closest Biovore (within 100m) and positions 2-5m in front of it between the Biovore and the player. Acts as a shield for its parent Biovore

• Aggressive (default) - positions 1-5m around the enemy, predicting their movement (clamped to 7m prediction), minimum 10m distance for position selection

Enemy Behavior

State Flow

SPAWN
  │
  ▼
IDLE (no enemy) ──── floating in place, 4.5 speed
  │ Enemy detected within 20m (AlertDistance)
  ▼
ALERT ──── speed increases to 6.5, begins pursuit
  │
  ▼
COMBAT (two parallel systems):
  │
  ├── Close Hit Timer:
  │     Enemy within 10m for 5s → enables fast melee charge
  │
  └── Attack Priority (ActiveSelector):
        1. DISTANT HIT (HEAVY token, 10-15m) → Explosion kata (1s wind-up + 2s flight)
        2. CLOSE HIT (HEAVY token, 0-5m, after 5s timer) → Melee kata (0.5s wind-up + 0.7s flight)
        3. APPROACH → Move toward enemy
        4. STANDBY → Orbit at 10-15m, strafe (5s cooldown, 10s duration)

Standby Behavior

When a mine can't attack (no HEAVY token, or outside attack range), it orbits at 10-15m:

• Strafe cooldown: 5s (±1s spread)

• Strafe duration: 10s (±0.5s)

• Wait between strafes: 2s

• Maintains preferred distance of 10-15m from target

Detonation Triggers

Why Some Melee Attacks Are Safe and Others Aren't

The mine always detonates when it dies - the question is where it is when it explodes:

• Strikes WITH canKnockback = True: The knockback impulse pushes the mine away before the detonation triggers → explosion at safe distance → safe

• Strikes WITHOUT knockback: The mine dies in place, right next to you → detonates on the spot → dangerous (4m blast radius)

• For a full list of safe and unsafe attacks see this section below.

Damage Types

Explosion

Both guardbreak and pervasive - unparryable (pervasive) and breaks held block (guardbreak). Must dodge. The detonation deals dmg_type_bioweapon_explosive - its own damage category, neither ranged nor melee, so ranged-damage-reduction and melee-damage-reduction perks do nothing against spore explosions. Only Damage Reductions perks that are type-agnostic or reduce health damage (HEALTH_ONLY_DAMAGE_SENSITIVITY) will reducing spore damage.

Acid Shower (Acid Mine Only)

• ability_acid_shower - area denial ability cast after a 5-second delay

• Details of the acid shower damage are in the ability controller (not fully extracted)

Chain Detonation System

When one mine explodes, nearby mines within 3m chain-detonate. Each hop shrinks the radius by 1m, so chains reactions will often die out even within a large swarm of spores.

Safe & Dangerous Player Melee Attacks

Melee Knockback - Which Attacks Push Mines Safely?

Attacks with canKnockback = True push the mine away before detonation (safe). Attacks without knockback kill the mine in place (dangerous - explodes in your face).
