- Six enemy classes: Shambler, Runner, Brute, Crawler, Spitter, and Horde Waves
- Threat scaling: enemies get stronger as you climb floors 1 through 30
- Counter tactics: chokepoints, barricades, and ranged focus fire beat every threat
- Special infected: prioritize Spitters and Brutes first in any wave
All Characters Overview
The character roster in 30 Floors Up is built around one core conflict: survivors defending a ruined 30-story tower against waves of the undead. Every character you encounter falls into one of two groups — the player-controlled survivors holding the floors, and the infected climbing the stairwells to reach you. Knowing each character's stats, behavior, and weakness is the single biggest factor in surviving the night waves.
Each infected character has a distinct attack pattern and counter. Teams that learn the roster clear floors faster, waste less ammo, and lose fewer barricades than teams that treat every zombie the same.
| Character | Type | Threat | Health | Speed | Primary Danger |
|---|---|---|---|---|---|
| Basic Zombie (Shambler) | Common Infected | Low | Low | Slow | Horde pressure |
| Runner Zombie | Common Infected | Medium | Low-Medium | Fast | Breaks through gaps |
| Brute Zombie | Special Infected | High | High | Slow | Smashes barricades |
| Crawler Zombie | Special Infected | Medium | Low | Medium | Ambushes at floor level |
| Spitter Zombie | Special Infected | Medium-High | Medium | Slow | Acid area denial |
| Horde Wave Enemies | Wave Event | Scales | Mixed | Mixed | Multi-stairwell assault |
Common Infected Characters
The two common infected characters form the backbone of every wave. They appear in large numbers on lower floors and remain present all the way to the rooftop, making them the enemies you will fight most often.
Basic Zombie (Shambler)
- Threat: Low
- Walks toward the nearest player with melee swipes
- Appears in large hordes on lower floors
- Counter: headshots with the starting pistol conserve ammo; funnel groups into hallways for shotgun blasts
Runner Zombie
- Threat: Medium
- Sprints directly at players on sight
- Often slips through barricade gaps
- Counter: barricade stairwell entrances and shoot Runners as they funnel through narrow chokepoints
Runners do not attack structures aggressively, but their speed means any gap in your defense line turns into a breach. Never let Runners reach open floor space — they are at their most dangerous when you are fighting in the open.
Special Infected Characters
Special infected are the characters that decide whether a defense holds or collapses. Each one forces you to change tactics, and each appears more frequently the higher you climb.
Brute Zombie
- Threat: High
- Armored heavy hitter that smashes barricades
- Slow turn speed and long attack recovery
- Counter: kite around obstacles, headshots with rifles, teammates focus fire
Crawler Zombie
- Threat: Medium
- Crawls low, slips under gaps, lunges at legs
- Hides behind debris before striking
- Counter: check floor-level sightlines; keep a shotgun or melee weapon in tight stairwells
Spitter Zombie
- Threat: Medium-High
- Lobs acid puddles that force you out of position
- Long wind-up, low mobility
- Counter: kill at range before it zones your barricade line; never repair while standing in acid
| Character | Best Weapon Match | Positioning Rule |
|---|---|---|
| Brute | Rifle / Assault Rifle (ranged headshots) | Never melee; kite around obstacles |
| Crawler | Shotgun / downward melee swings | Watch floor level behind barricades |
| Spitter | Rifle (long range) | Engage before it enters spit range |
When a mixed wave hits, kill Spitters first, then Brutes, then everything else. Spitters dismantle your defensive position without ever touching you, and an uncontrolled Brute erases barricade lines in seconds.
Horde Waves and Event Characters
Horde Wave enemies are not a single character but a wave event that spawns mixed infected assaulting your floor from multiple stairwells at once. Their threat scales with your current floor, making late-game hordes on floors 21-29 the most dangerous encounters in the game.
| Wave Phase | What Happens | Recommended Response |
|---|---|---|
| Between waves | Calm period | Repair barricades, restock ammo, pre-build fallback lines |
| Wave start | Mixed types spawn from multiple stairwells | Each player covers an assigned stairwell |
| Mid wave | Special infected join the assault | Focus fire Spitters and Brutes on sight |
| Defense failing | Barricade line breaking | Fall back up a floor, re-establish a chokepoint |
Assign stairwells
Before the wave hits, assign each survivor one stairwell to cover so no entrance goes unwatched.
Stockpile ammo and tools
Use the calm between waves to fill reserves and hand repair tools to a dedicated repairer.
Pre-build a fallback line
Build a second barricade row one floor up so a collapsed defense becomes a retreat, not a wipe.
Execute target priority
During the wave, call out Spitters and Brutes immediately and focus them down before common infected.
Horde wave timing is predictable. Because you always get preparation time between waves, the teams that spend it repairing and reinforcing consistently outperform teams that loot mid-wave.
Roster Mastery Checklist
Work through this checklist to confirm you have mastered every character in the roster.
Character Mastery Goals:
- Identify all five infected types on sight without hesitation
- Clear a floor 11-20 night wave without losing a barricade line
- Kill a Brute using ranged headshots only
- Shut down a Spitter before it lands an acid puddle on your position
- Survive a multi-stairwell horde wave on floors 21 or higher
Floors 1-5 are the tutorial zone for the roster. Use the low-threat Shamblers there to practice headshot economy and chokepoint funneling before the special infected appear in force from floor 11 onward.
FAQ
Q: How many characters are in 30 Floors Up?
The current roster includes five distinct enemy characters — the Shambler, Runner, Brute, Crawler, and Spitter — plus mixed Horde Wave events that combine all types. Survivors are player-controlled and fully customizable rather than fixed characters.
Q: Which character in 30 Floors Up is the most dangerous?
The Brute is the highest individual threat due to its high health, high damage, and ability to smash barricades. However, Spitters are arguably more disruptive because their acid puddles force you out of defensive positions without engaging you directly.
Q: Where do special infected characters start appearing?
Common infected dominate floors 1-10, while special infected like the Brute appear more frequently on higher floors, especially from floor 11 upward. Floors 21-29 feature elite versions with the heaviest spawn rates.
Q: What is the best way to counter all character types at once?
Layered barricades at stairwell chokepoints, a spike trap behind the front row, and assigned stairwell coverage per player. This setup funnels every character type into your line of fire, and target priority — Spitters first, Brutes second — handles the rest.
