I have not played Team Fortress 2 (so forgive me if I've missed any details), but I couldn't help but notice that the Spy uses masks to disguise himself. To his teammates, he looks like he's just wearing a mask, but to the enemy team, he looks like whoever is on his mask. How do the masks fool the other team (from the point of view of the actual team and not the players)?

Was this ever explained anywhere?

If you're taking the Spy-masks (or really, anything in Team Fortress 2) at face value (bah-dum-tiss), then you really shouldn't. TF2 is a game that prides itself on over-the-top, tongue-in-cheek, absurdist humour:

Surreal humour (also known as absurdist humour) is a form of humour predicated on deliberate violations of causal reasoning, producing events and behaviours that are obviously illogical. Constructions of surreal humour tend to involve bizarre juxtapositions, non-sequiturs, irrational or absurd situations and expressions of nonsense.

Wikipedia (Emphasis mine).

The masks are just a bit of hilarious flavor for a team to know which class a friendly Spy disguised as. It's supposed to be a joke, either aimed at the Spy's 'terrible' attempts to disguise himself, or at the enemy team for falling for such a ridiculous disguise (or both).

However the Spy does in fact disguise himself well: pretty much identical to a member of the other team, (from their perspective). Therefore, the masks themselves do not portray an accurate representation of the Spy's skill at disguising.

    The Meet The Spy video makes it pretty clear that the Spy is in fact very good at disguising. Commented May 1, 2015 at 12:28

    As an aside - an enemy spy disguised as a spy will always appear disguised with a random paper mask - sometimes a spy.

The device used by the Spy in order to disguise is known as The Disguise Kit. This kit contains a few sticks of his iconic cigarettes, along with a not often mentioned piece of technology known as the Spytron 3000:

TF2 Spy Disguise Kit

Although not much is revealed about it, this device is a technological breakthrough in infiltration, giving the Spy this great power of tricking the enemy team into seeing whoever the Spy wants them to see.

Seeing as how the disguise is achieved technologically, and based on the visual effects of cloaking (see Meet the Spy at 2:09), the most likely cause of the disguise is in the form of a holographic projection. As for why the teammates can see the the masks and "undisguised body", we can only speculate: perhaps this is caused by an adjustment to the hologram, tuned to a frequency known only to the own team, or perhaps it's a representation of a close familiarity with the Spy by his own team members (I would recognize that walk anywhere; that's my friend, Monsieur Blu Spy, not an enemy Pyro).

But then what are the masks used for? And if the masks aren't small enough to be kept in his Disguise Kit, then where does the Spy then get them from you ask? Don't ask. Perhaps the same place weapons in the secondary slots when they aren't holding on to them. (which might explain why the running speed of the Heavy Weapons Guy is so slow even when he is holding a smaller weapon...)


The nine men (or 8 men and 1 woman, depending on who you ask) in Team Fortress 2 are, in fact, dead and trapped in Limbo. They fight out the same battles over and over from different perspectives for all eternity, never guessing their real situation. They don a wide variety of hats to try to prove to themselves that they're not the same person as their counterpart on the other team. They make up holidays to try to track time, even though time stands still for them. They've long since forgotten their real names, remembering only the role they fill.

These poor souls try hard to ignore the truth. So if they see a picture of their teammate on a paper mask, they'll believe the wearer is in fact their teammate.

    What's the source of the limbo theory? I haven't been keeping up with comics, and you might want to substantiate this for others who haven't. Commented May 2, 2015 at 2:23

    This theory is not cannon (and it's not the first time I have heard it). It is still entertaining, but could you please post a source as best as you can to the original source of the theory?

  • Nah, it's not canon. I can't seem to find the article/video where I heard it, but the version I heard said the Medic was actually Satan, keeping the other characters in limbo to torture them...so I don't think it's the original source. One could even say this interpretation is intended to be surreal humor. (Or surreal horror?)

If you have seen, there is an item such as the Spytron 3000. This is all speculation, but possibly the Spytron 3000 has a programmed feature, allowing you to choose whoever gets to see you and who shall see a different person. The feature might also project the mask to tell the team that he is disguised, which is why the spy can see, yet the mask has no eye slots. Hope this helps.


Let's say the Spy is on the Blue Team.

All members of the Blue Team see a Spy wearing a mask (let's say the Medic mask), so they know it's a Blue Spy.

Members of the Red Team however, see a Red Medic. This makes them believe that the (disguised Spy) is on their team.

However, there are some giveaways.

  1. SPY CHECK! Friendlies don't take damage from friendly fire. Hence why you might see a Pyro running around torching his own team on occasion.

  2. Enemy name plates don't appear. This is the only giveaway that a member of your team might be a disguised Spy.

  3. (A little less obvious) Friendlies also don't have a collision detection. That means you pass through friendlies, but collide with enemies.

However, to try and explain why this is the way it is, would probably need knowledge of developer intent, which I, unfortunately, do not possess.

    Good answer on the mechanics and tactics, but unfortunately it's not what the question was asking :)

    It's not like Pyro needs a reason to randomly hose down both friend and foe with the flamethrower. Any excuse will do. Commented May 1, 2015 at 12:27

    Also worth noting - Spies max movement speed is Min(Spy.MaxSpeed, DisguisedClass.MaxSpeed) - so if you see a scout moving surprisingly slowly. it might be a spy. Commented May 1, 2015 at 14:37
  • Enemy name plates don't appear. I haven't played TF2 in years, but from my experience, enemy Spies always carry your own name as their nameplate. So every time I see a teammate with my name over his head, I knew it was an enemy Spy.

    @Nolonar Not necessarily your own name, but the name of someone on your team, yes. I think they get the name of someone from the class they're disguised as, or a random player on the team if no one is that class. Commented May 2, 2015 at 19:27
