# Enemies
|
||
|
||
All **6 enemy types** in MeatSlicer, plus elites, drops, and the exact difficulty-scaling formulas. Pulled from `js/enemies.js` and `js/rooms.js`.
|

|
||
## Enemy roster
|
||
|
||
### Shambler
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 26 |
|
||
| Base speed | 55 |
|
||
| Contact damage | 1 |
|
||
| Hitbox radius | 18 |
|
||
| XP | 1 |
|
||
| First appears | Floor 1 (spawn weight 40) |
|
||
|
||
The basic chaser. Shuffles toward you with a sinusoidal wobble. Individually harmless, dangerous in the packed waves of later floors.
|
||
|
||
### Runner
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 12 |
|
||
| Base speed | 236 |
|
||
| Contact damage | 1 |
|
||
| Hitbox radius | 15 |
|
||
| XP | 1 |
|
||
| First appears | Floor 1 (spawn weight 25) |
|
||
|
||
Extremely fast, fragile chaser — over 4× the Shambler's speed. They arrive first and force you to keep moving.
|
||
|
||
### Spitter
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 20 |
|
||
| Base speed | 60 |
|
||
| Contact damage | 1 |
|
||
| Hitbox radius | 18 |
|
||
| XP | 2 |
|
||
| First appears | Floor 2 (spawn weight 18) |
|
||
|
||
Ranged kiter. Holds 190–250 px away from you — approaches if you're farther than 250 px, retreats if you're closer than 190 px. Fires a gore bolt (speed 220, damage 1, 3 s life) when within 420 px, every **1.9 s**. Elite Spitters fire a 3-shot fan (0.25 rad spread) every **1.1 s**.
|
||
|
||
### Splitter
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 30 |
|
||
| Base speed | 70 |
|
||
| Contact damage | 1 |
|
||
| Hitbox radius | 21 |
|
||
| XP | 1 |
|
||
| First appears | Floor 2 (spawn weight 16) |
|
||
|
||
Chaser that **splits into 2 Minis on death** (non-elite Splitters only). Slightly tankier than a Shambler. Explosions and AoE that kill the Minis with the parent are valuable here.
|
||
|
||
### Mini
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 6 |
|
||
| Base speed | 120 |
|
||
| Contact damage | 1 |
|
||
| Hitbox radius | 10 |
|
||
| XP | 1 |
|
||
| First appears | Only from Splitter deaths and boss summons |
|
||
|
||
Tiny, quick chaser with a small hitbox. Never spawns directly from room waves.
|
||
|
||
### Exploder
|
||
|
||
| Stat | Value |
|
||
|---|---|
|
||
| Base HP | 14 |
|
||
| Base speed | 110 |
|
||
| Contact damage | 2 |
|
||
| Hitbox radius | 16 |
|
||
| XP | 2 |
|
||
| First appears | Floor 3 (spawn weight 14) |
|
||
|
||
Suicide bomber. Charges at you; within 56 px its **0.5 s fuse** lights (it flashes). When the fuse ends — or when it's killed by anything — it detonates: radius 70 (fuse) / 60 (killed), **2 damage**. The blast only hurts *you*, not other enemies. Kill them at range or bait the fuse and back off.

## Spawn weights
|
||
|
||
| Enemy | Floor 1 | Floor 2 | Floor 3+ |
|
||
|---|---|---|---|
|
||
| Shambler | 40 | 40 | 40 |
|
||
| Runner | 25 | 25 | 25 |
|
||
| Spitter | — | 18 | 18 |
|
||
| Splitter | — | 16 | 16 |
|
||
| Exploder | — | — | 14 |
|
||
|
||
Weights stay flat once unlocked; floors get harder through stat scaling and wave size, not new mixes.
|
||
|
||
## Elites
|
||
|
||
Any wave-spawned enemy can roll as an **elite** (gold ring, HP bar pip):
|
||
|
||
- Chance: `min(0.03 + floor × 0.02, 0.20)` — 5% on floor 1, capping at 20% from floor 9.
|
||
- **HP ×2.6**, speed ×0.9, contact damage **+1**, radius ×1.45, XP ×3.
|
||
- Drops: 3× XP plus 3–5 bonus gems, **18% + luck×10% chance of an item pedestal drop**, otherwise 60% + luck×20% chance of ammo.
|
||
|
||
## Drops
|
||
|
||
| Kill | XP | Other drops |
|
||
|---|---|---|
|
||
| Normal enemy | Its XP value | Ammo: 7% + luck×4% · Heart: 2.2% + luck×3% |
|
||
| Elite | 3× XP + 3–5 bonus | Item: 18% + luck×10% · else ammo: 60% + luck×20% |
|
||
|
||
Your on-kill items (Volatile Bile, Bloodlust, Vampire Dentures, Dead Man's Switch) trigger off every kill — see [items.md](items.md).

||
## Difficulty scaling
|
||
|
||
Every enemy's stats are computed at **spawn time** from three factors: floor, your power score, and pressure.
|
||
|
||
**Power score** = `(your level − 1) × 0.5 + (sum of all your item tiers)`
|
||
|
||
**HP:**
|
||
```
|
||
base HP × (1 + 0.22 × (floor − 1)) × (1 + 0.05 × power) × (elite ? 2.6 : 1) × pressure
|
||
```
|
||
|
||
**Speed:**
|
||
```
|
||
base speed × (1 + 0.04 × (floor − 1) + 0.01 × power) × (elite ? 0.9 : 1) × rand(0.9, 1.1) × pressure
|
||
```
|
||
|
||
**Contact damage:** flat per type (elites +1) — it **never scales with floor**. What kills you late-game is volume, speed, and HP pools, not bigger hit numbers.
|
||
|
||
**Pressure** (see [gameplay.md](gameplay.md#pressure-dynamic-difficulty)) ranges 0.75–1.60 and multiplies both HP and speed. Playing flawlessly pushes it up; getting hit pulls it down.
|
||
|
||
### Example: Floor 10 Shambler
|
||
|
||
Level 8 player (3.5 power) with 8 item tiers (8 power) → power 11.5, pressure 1.2:
|
||
|
||
```
|
||
HP: 26 × (1 + 0.22×9) × (1 + 0.05×11.5) × 1.2 = 26 × 2.98 × 1.575 × 1.2 ≈ 146
|
||
Spd: 55 × (1 + 0.04×9 + 0.01×11.5) × 1.2 ≈ 55 × 1.475 × 1.2 ≈ 97
|
||
```
|
||
|
||
vs. 26 HP / 55 speed on floor 1. Build damage accordingly.
|
||
|
||
## Wave sizes
|
||
|
||
Combat rooms spawn `3 + ceil(floor × 1.4)` enemies in wave 1, plus a second wave (×0.7) from floor 2 and a third (×0.5) from floor 4. Full table in [gameplay.md](gameplay.md#waves-per-combat-room). Hard cap: 72 enemies alive at once.
