间谍反制战术

间谍是专门对你们队伍进行欺骗与破坏的特务，他们十分狡猾。他们会使用隐形手表来帮助自己隐身，或者用伪装工具 伪装成你的队友以进行间谍活动，并将目标直接背刺。最好防御间谍的方法就是观察：他仅仅只有这几种方法伪装自己，所以有经验的玩家可以迅速发现不对劲的地方。间谍的战斗能力较为低下，所以一般他们打不过就会立刻逃跑。请记住：间谍有着许多方式去欺骗你和你的队友，包括使用死亡之铃假装装自己已死。如果你们队伍能定时进行间谍检查，间谍就很难对你们造成威胁。而火焰兵可以用他的火焰喷射器快速筛选出间谍。

一般策略

属性	相应的反制战术
职责	间谍会尝试在你们的后方用自己的伪装和隐身能力干扰你们，请进行必要的间谍检查。 一个伪装的间谍行动不会像你的队友一般自然。比如，他不能进行攻击且穿过你们队的任何一个人。 一个高超的间谍可以以一己之力对抗整个没有协调的队伍，请及时与队友报告间谍和他的可能位置。 你可以通过查看间谍的出装以判断他的总体的游玩风格。 某些武器，比如火焰兵的拆迁者和狙击手的电击背脊盾，有特别的反间谍功能。
生命值	间谍的身板较脆弱，其一般生命值为125。在其暴露后一般不难杀死，但他可能会通过隐身来减免受到的伤害或用死亡之铃来抛下一具假尸体。
速度	一般来讲，间谍的移速要比兵种的平均移速快一点。当间谍进行伪装时，他的移速会与他当前伪装的这个兵种的移速相同。（除了侦察兵） 一个移速比平常慢的侦察兵一定是间谍！
武力	在直接战斗中，间谍的武器较弱。 间谍可以看到敌方玩家的生命值，这样他可以确认敌方玩家是否可以一枪干掉。 如果间谍神不知鬼不觉地潜入了敌方阵地并摸到了敌人的后背，他就可以背刺干掉那个敌人。 一个高超的间谍会使用trickstabs解决他遇到的敌人。

武器

主条目： 间谍的武器

副武器

武器	相应的反制战术
左轮手枪 + 其所有皮肤	左轮手枪射速较快，且很精准。请进行不规律移动以加大间谍射中你的难度。 当你的生命值低于50%时要特别注意：间谍可能会用左轮手枪把你解决掉。请在当残血时对那些可疑的队友进行间谍检查。 如果间谍的身份被暴露且其想决一死战，他一般会向后后退以制造距离优势，但是，其向后移动速度比向前跑要慢。所以你仍可以借助掩体将其放倒。 大多数武器近距离攻击伤害要比左轮手枪要高。除非间谍十分有信心将你放倒，否则还是想一想他的逃跑路线吧。
大使手枪 + 其所有皮肤	在直接战斗中，间谍会使用大使手枪瞄准你的头部以造成爆击伤害。向其扫射或不规律跳跃以躲避其射击。 大使手枪某种意义上要比左轮手枪要弱，其造成更少的身体伤害且开火速度更慢。除此之外，在其射击后有一段时间间谍不能造成爆头伤害。 间谍检查任何瞄准你的队友。
陌生人	一个使用陌生人的间谍会获得40%的额外隐身能量且其每击中一个敌人就可以积攒隐身能量。当你找到一个装备该武器的间谍时，将其点燃或向他扔瓶手道或疯狂的牛奶使他无处遁形。 陌生人相对于左轮手枪制造更少的伤害，在直接战斗中要比其弱许多。
执法者	执法者在伪装时伤害+20%，但同时其开火速度也下降了20%。如果你躲过了他的第一枪，那么接下来反杀回去就简单很多了。 执法者无视伤害抗性。 如果你使用部分能给你带来抗性的物品，比如疫苗注射枪或军队的支援，那么还是建议你不要太过放肆地追着间谍跑。
菱背响尾蛇	菱背响尾蛇会在间谍成功背刺敌人或破坏建筑时储存一次爆击。然而，其一般伤害相对较低，合理的反间谍措施可以成功将其压制。

近战武器

武器	相应的反制战术
刀子 + 其所有皮肤	如果你听到附近的队友的尖叫或者是在右上角击杀提示那里看到有队友被背刺，那么请多多转圈以防止成为下一个背刺受害者。 刀子相对于其他兵种的近战武器来讲制造的伤害较少。如果一个间谍失去了伪装，那么他可能会用左轮继续硬刚或者是借助隐身逃跑。 一个持着刀子的间谍很有可能会想找到你珍贵的后背然后刺下去。避免与间谍近战，因为你的一个不小心的转身就可能会被间谍送回重生室。因此，请使用远距离武器攻击他。 除此之外，提防那些跑到楼梯顶或者躲在角落的“队友”，他们很有可能是想背刺你的间谍。 如果你发现一个间谍即将背刺你的队友了，而你无法及时击杀他时，尝试将其击退！士兵和爆破手可以利用爆炸将间谍炸飞，而火焰兵可以使用压缩气爆将间谍推开。
永生的回报 + 其所有皮肤	永生的回报会使得间谍在背刺一个人后立刻伪装成他的样子，且不会出现击杀提示，也不会有任何声音。因此，在你被背刺后，立刻告诉你的队友！（用say_team） 与其它反间谍措施不同的时，当你在与团队一起行进时请注意后背，间谍可以将只顾着往前冲的傻傻敌人全部背刺。 永生的回报使得间谍的隐身能量消耗更快，且其伪装时也会消耗满格的隐身能量，使其在伪装后的一段时间无法隐身。
密谋者的苦无	密谋者的苦无会将间谍的最大生命值减少至70点。如果他仍没有背刺任何一个敌人，拿下他并不是件难事。 较低的最大生命值很有可能会使间谍装备死亡之铃以防不时之需。 对任何可疑的被超量治疗的队友进行间谍检查，尤其是当附近没有医生时。
暴利杀手	暴利杀手会在间谍成功背刺一个敌人后将间谍隐身能量重新填满且给予速度加成，这会让他逃跑更方便。 一个优秀的间谍会在背刺后的速度加成时间内尝试将你拿下，可要当心！ 该武器会使其最大生命值降至100点，在他进行背刺前你更容易把他干掉了。
神奇的冰柱	神奇的冰柱会使被背刺的敌人化作冰雕。当你发现前面有一座这样的冰雕时，间谍很有可能没跑远，抓紧进行间谍检查！ 自己队的火焰兵可以暂时将间谍的神奇的冰柱融化，且其被融化后会发出巨大声响。在其恢复前，这个间谍都背刺不了你们了！

伪装工具

武器	相应的反制战术
伪装工具	如果你发现你无法直接穿过你面前的队友，那么就说明他是敌方间谍！ 随时使用火焰喷射器、瓶手道或任何可以造成流血效果的武器进行间谍检查。敌方间谍伪装时仍会受到你队的攻击。 更多信息，还请查看：间谍检查

隐身手表

主条目： 隐形

• 隐身间谍在受到液体效果（如瓶手道）、点燃或者流血时会露出身形。尝试使用这种武器对此任何可疑区域进行间谍检查。但注意，间谍的隐身可以使这些效果持续时间少一半，所以请抓紧时间！
  • 隐身的间谍刚从水中出来时身上会有水滴效果。
• 间谍在隐身时可以使用医疗包或者是弹药包。所以当你看到医疗包或者弹药包无缘无故失踪时，说明这附近有隐身的间谍。
• 伪装的间谍可以通过敌方的补给器给自己弹药补给和治疗。当你看到补给器其中一条治疗光束浮在空中时，请进行间谍检查。
• 间谍在隐身时撞到敌人怀中时会显现自己的暗色轮廓，当你看到隐身间谍的暗色轮廓时，对其进行持续攻击以逼他现形。
• 一个隐身的间谍仍能发出声音。你可能会听到他的脚步声、他从高处摔下来的惨叫声和骨折声，又或者他的语音回应。而在其解除隐身时，也会发出一种独特的声音。
• 如果你看到一个间谍隐身了，或者是在高生命值下挂了，又或者在你眼皮底下跑了，那就赶紧告诉你的队友！

武器	相应的反制战术
隐形手表 + reskins	If a Spy tries to flee with the Invisibility Watch, grab surrounding ammunition boxes and dropped ammo packs from fallen players to deny him extra cloaking time. Watch nearby pickups carefully and attack their location if they disappear, as you may catch the Spy red-handed.
隐形刺客	Spies using the Cloak and Dagger will often wait in corners or secluded areas to recharge their Cloak. Many Spies use the same spots; check commonly trafficked areas or places you would hide in yourself. With the Cloak and Dagger, the Spy can hide nearly anywhere. For instance, he might hide above high-traffic areas, then drop down behind passing enemies and backstab them. When using the Cloak and Dagger, the Spy cannot pick up ammo to replenish his cloak meter while cloaked; this limits the distance he can quickly travel. Decloaking with the Cloak and Dagger makes a louder sound than decloaking with the Invis Watch does. Listen closely!
死亡之铃	The Spy can choose to activate the Dead Ringer upon taking damage to feign his death. When doing so, he is cured of fire and bleeding, and temporarily gains speed and damage resistance. If you believe the Spy is using this to sneak behind your team, predict where he will eventually decloak. Jarate and Mad Milk are not cured even if a Spy feigns death. If possible, have at least a teammate equip one of the said weapons to help detect a Dead Ringer Spy. When the Spy decloaks, the Dead Ringer emits a very loud, distinctive sound. If you hear it, look for a Spy immediately! The Dead Ringer can only be activated when fully charged and cannot be refilled with ammo pickups or Dispensers. If the Spy has uncloaked recently, take him out before he recharges using the effects of weapons like the L'Etranger or Big Earner. You might identify a Dead Ringer Spy based on his behavior, which is important information to relay to your team. If a Spy dies in a single weak hit, he is probably faking his death. The Spy cannot attack while the Dead Ringer is prepared. The Dead Ringer can replicate or fake many in-game mechanics, but not all. For more information, see the "Feign death effects" section of the Dead Ringer article.

Buildings

• Even if the Spy is disguised, you can still see him reach out and place Sappers on buildings. Keep an eye out for this animation to quickly figure out which teammate is the Spy.
• Pyros with the Homewrecker are excellent for defending buildings; it only takes one strike to dislodge Sappers, compared to the two strikes required by the Engineer's default Wrench.
• Keep special notice of your team's Teleporters. If left unguarded, a Spy can place a Sapper on one end and continue to replace those that are removed on the other end, eventually sapping more health than what the Engineer can repair and slowing your team's reinforcements.
• The Spy may put a Sapper on a Teleporter entrance and take it as soon as the Engineer removes it. Do not stand on your Teleporter Exit, as the Spy may Telefrag you.

Weapon	Anti-Spy strategy
电子工兵 + reskins	A Spy can replace any Sappers removed from a target building faster than an Engineer can remove the Sapper and repair the building; locate the disguised Spy and kill him before removing his Sappers. An Engineer who needs to leave his buildings should have a teammate, preferably a Pyro or another Engineer, guard them while he is away. Spacing Engineer buildings from each other forces the Spy to cover more ground between Sapper placements, giving your team more time to react.
官僚式录音机	The Red-Tape Recorder quickly downgrades buildings to their level 1 version, but takes some time to completely destroy them. You have more time to kill the offending Spy before restoring the affected buildings. When your team's Sentry Gun is downgraded, that is a prime time for the enemy team to push in. Your team should support the Engineer while his buildings are re-upgraded. An enemy Spy with the Red-Tape Recorder can waste the time and metal of an allied Engineer using the Gunslinger's Mini-Sentry Guns, as the Recorder’s slower destruction rate means the Engineer must wait longer before placing another Mini-Sentry. Mini-Sentry Guns are often placed at the frontlines away from other buildings, so gun down the Spy before he causes more problems.

Telling Them Apart

See Spychecking for more strategies.

• Your team can always hurt an enemy Spy. A stray bullet or explosion may reveal a cloaked Spy.
• A disguised Spy can't pass through you like teammates can. If you bump into a teammate and can't pass, they are a Spy.
• The Spy cannot copy special abilities or use weapons of other classes. A strangely slow Scout or a Medic who is not healing warrants suspicion.
• Consider where allied classes are typically found and are played. For example, two common disguises are the Sniper and Spy. The Sniper is usually played away from allies on high ground, while your Spy should be with the enemy team!
• Teammates who appear overly-fixated on other allies, suddenly beeline towards friendly targets, ignore objectives, refuse to fire their weapon, or otherwise deviate from typical behavior should cause concern.
• Note how teammates interact with the environment. A few situations might call for a Spy-check, including a teammate who is at full health but can pick up a health kit, an injured teammate moving away from your respawn area, or team-specific doors not opening for a teammate.
