Part 7

Act Like the Enemy: To avoid drawing attention, run backwards and throw a grenade forward (avoiding gas grenades unless friendly fire (FF) is off) to simulate combat. This requires map knowledge to avoid running in random directions.

Pick an Appropriate Disguise: Disguise as an Engineer to approach Sentry Guns (SGs) without suspicion. Disguise as a Sniper to approach Sniper perches. Avoid disguising as a Scout, as their movement speed differs significantly from a Spy, and avoid disguising as a Medic, as enemies will expect healing and may become suspicious if you refuse.

Maintain Your Disguise: You lose your disguise if you use any weapons except Grenades and Gas Grenades. Bumping into an enemy, or picking up a flag, key, or securing a command point also breaks your disguise.

Use Feign Death: To disappear quickly, use the 'Feign Death' command. This makes you appear dead to observers, but you can resume by selecting 'stop feigning'. Be aware that experienced players may still shoot bodies as a Spy check. You cannot get up if an enemy stands on you. 'Feign Silently' is similar but omits the death-groan sound and is more useful.

Eliminate Sentry Guns (SGs): Spies are effective against SGs. When disguised, SGs will not fire on you. Lob two normal grenades at the SG when unobserved, then move on.

Master the Backstab: Use your knife to kill enemies in one hit by stabbing them in the back. This is highly effective against groups of Snipers whose attention is typically focused elsewhere.

Utilize Grenades: Spies do not lose their disguise when throwing Grenades. Ensure you are stocked with grenades before entering enemy territory to maximize damage before your disguise is potentially lost.

Sniper Spot Ambush: Feign silently in a common Sniper spot. When a Sniper arrives and is distracted, pop up and knife them. Repeat this tactic.

Gas Grenade Utility: Throw a Gas Grenade into Sniper areas or other locations to cause hassle for the enemy, but only if you can do so undetected or if you are about to die. Gas grenades cause minor damage and annoyance, similar to Pyro's flame grenades.

Recognize Detection: If an enemy repeatedly shoots you, they have likely figured out your disguise. Drop the facade and engage with your Knife, Super-Shotgun, and grenades.

Tranquilizer Gun Takedown: The Tranquilizer Gun causes enemies to have illusions and slows their reflexes. Shoot an enemy with it to slow their movement, then take advantage by stabbing them in the back.

Spy as a Scout: A Spy can be more effective than a Scout for reconnaissance. Infiltrate the enemy base and report enemy defenses, such as SG locations and potential Soldier (So) campers, to your teammates.
