I first saw this term in use for neutral units in Warcraft 3 (released 2002), and then that got carried through derivatives such as Dota (2003).

Was Warcraft 3 the first time creep was used as a reference for this class of units or was it in use prior?

Example usage from Defense of the Ancients 2 (2010) wiki:

Creeps are a type of unit within Dota 2 that heroes can interact with, but do not have direct control over by default (see Chen, Enchantress and Helm of the Dominator). There are two types of creeps: lane creeps and neutral creeps. Both types of creeps can be killed by players for gold and experience.

Example usage form League of Legends (2009) wiki:

Minions, also known as creeps, are expendable allied units that are generated automatically to charge into battle with the purpose of attacking enemy units in the lanes they are assigned.

  • Of course not. The word creep is used at least in StarCraft ... and there may be some earlier games adopting this word.

  • I believe the neutrals in Starcraft were called "critters" instead. At least I don't remember them being called creeps.

  • It goes back to at least the original Warcraft RTS game.

WoWWiki defines creep:

A creep is any monster in the game or any non-quest-giving and non-shopkeeper NPC combatant.

Typically used on Battle.net on Warcraft III. The term mob is more often used in World of Warcraft.

Comes from Warcraft III where the neutral (but aggressive) packs of monsters would guard certain areas from your armies. Originally, in Starcraft, creep was a layer of slime where zergs could build similar to blight.

As far as I can tell, creep was first used as a type of neutral creature in Warcraft III "to make its maps seem more like a world, rather than a game board. This will create an immersive atmosphere as well as create unique strategies and tactics."

World of Warcraft, 2004

The earliest definition in Urban Dictionary is from 2004 for Blizzard Entertainment's World of Warcraft:


New terminology for MOBs that Blizzard is trying to instill in the World of Warcraft playing community.

Character 1: Let's go kill that 'creep'.
Character 2: WTF is a 'creep'?
Character 1: Any bad guy we can kill.
Character 2: It is called a MOB you fucking looney tunes bitch.

WarCraft III, 2000

The term was used by Blizzard on their official preview website for Warcraft III: Reign of Chaos (aka War3 or WC3 or RoC, released 2002).

The oldest archive of http://www.blizzard.com/war3/neutrals/creeps.shtml is from 15th December 2001:

Even the most expert travelers must be wary, for in the exploration of any map they're bound to encounter a variety of Creeps. Creeps are neutral units that generally don't like you, regardless of what type of blood runs through your veins. They will attack unprovoked, and they're very protective of their camps. This camp loyalty means that the Creeps will be in the same place on any given map anytime you explore that map. If your hale and hearty band of travelers can keep their wits about them long enough to do battle with the various Creeps that populate each map, they stand to profit from their bravery. It's a well-known fact that once vanquished, Creeps give up varying amounts of experience, gold, and sometimes even valuable, mystical items--the tougher the Creep, the greater the reward. Creeps also give up the ghost permanently when you vanquish them, so your stalwart troops won't ever have to re-vanquish any Creep respawns. Some Creeps might be willing to suppress their distaste for you long enough to join your cause...for the right price. These Creeps can be purchased at the Mercenary Camp. Otherwise, expect to stumble across hostile Creeps near town exits, at various choke points around the map, around extra Gold Mines, and defending Neutral Buildings. Ah the variety of Creeps you'll see...this page lists but a few of them C r e e p s Ogre Lord Using their immense bulk to terrorize their lesser ilk into service, Ogre Lords are often encountered guarding Gold Mines, Healing Pools and other valuable locations. Although they do not cast spells, Ogre Lords make up for their lack of magic with pure brawn, blasting their tree-trunk sized clubs into their enemies' skulls with unequaled fury.

The Blizzard Warcraft III preview homepage announced the creeps on December 14, 2001:

"Even the most expert travelers must be wary, for in the exploration of any map they're bound to encounter a variety of Creeps." Learn more about these units on the new Creeps page, currently featuring the Ogre Lord.

Earlier, it was used in 2000 Usenet in a Warcraft III preview.

The Infoceptor ÏÂÎÏ×ÉÌ %subj'Å×ÕÀ ÓÔÒÁÎÉÞËÕ: (http://www.infoceptor.com/information/war3/miscunits.shtml)

Warcraft 3 will feature a wide range of neutral creatures to make it_s maps seem more like a world, rather than a game board. This will create an immersive atmosphere as well as create unique strategies and tactics.


Creeps are wondering citizens of Azeroth, littered across the map. Upon encountered by players, they have different reactions depending on the players race and power. Some may attack outright, while other may offer their services of money, while other_s will give specific quests. Creeps are always armed, and hence are sometimes a threat, especially to fledgling forces.

StarCraft, 1997

There was creep in Blizzard's StarCraft which was released on 31st March 1998, but this was a different thing altogether. Mentioning it here for completeness only.

"Re: What's the best race?" - alt.games.starcraft - Josh Wooley - April 18, 1998:

the zerg are ok, but theyre units are usually weaker than the other 2. they are very cheap, however. everybodys favorite rush race, as far as i can tell. cant heal units/buildings, but they do regenerate themselves. have to build a fair amount of creeps though.

"The UBERLIST" - alt.games.starcraft - David Jarrett Fate quoting Blizzard rep Pat N. - Nov 14, 1997:

Q:Must creep be destroyed by certain weapon types?
A:Well, the way to destroy some creep is to take out Zerg buildings within the creep (when you do this, it will begin to recede).

But this isn't the same thing as a neutral unit. From the StarCraft Wiki:

reep colonies are zerg structures used to extend the creep. Colonies have to be established on pre-existing creep.

A creep colony can evolve into defensive structures: the sunken colony for ground defense, or the a spore colony for air defense and detection.

At some point, creep colonies were present in the game engine of StarCraft II. However, the creep colony was replaced by the creep tumor, and the defenses with the spine crawler and the spore crawler respectively.

  • That's right, in Starcraft zerg buildings had to be built on purple goo called creep. Which is why I'm still not certain if WC3 was the first use as a unit.

  • @AlexP: Thanks, I've edited it to make it clear StarCraft sludgy "creep" is a different thing altogether to the neutral units "creep".

I'd like to add that in Starcraft, creep is neutral and spreads on it's own after laying down a hatchery or creep colony. Because it's neutral it can be used by either player. Even a player's creep colony which generates creep and is shorthanded to "creep" often, is essentially a neutral unit in a lot of ways since it can't attack and what it makes benefits both players if they're playing as the zerg race on the map.

This isn't the only time a Blizzard game used a word from an older game with a slightly similar meaning, which makes me think that some of the culture at Blizzard lends itself to repurposing words from their other games intentionally from time to time, rather than it being a mere coincidence.

Blizzard also has (or at least used to have, back in the day) a close relationship with their players, and so words and phrases in the community do influence Blizzard's choice of words as well.
