"You are an amateur and a FOOL!" - Agent, when dominating another Agent.
The counterpart to Team Fortress 2's Spy class, however, she is female and supposedly originates from Italy.
The Agent is a ninth class in-game. She is a support class who specialized in destroying enemy defences, picking off high-value targets by cloaking behind the enemy line and disguising as anyone in the enemy's team. Unlike the Spy, the Agent can only disguise as a class if there is an enemy player using said class. Also unlike the Spy, the Agent can freely select between any player to disguise at any time. She is used for important picks, sometimes even changing the outcome of the match entirely. She is also specialized in taking out sentry nests, in which her sapper can disable and destroy any of the Mechanic's buildings.
The Agent does not have a primary, instead, her revolver secondary fills in the slot of a primary weapon, while the sapper takes the secondary slot. The Agent also has the ability to backstab a player, instantly killing them upon attacking from behind with her Knife.
The Agent used to be male and share lines with the Mechanic.
The Agent had several changes like outfit designs.
The Agent used to have a Top Hat and Bandana on his default avatar. These became cosmetic items after their gender switched.
The Agent used to not be able to disguise.
The Agent also used to have a different sound for cloaking and uncloaking.
The Agent's last normal design was her having messier hair, this then became her design for the Tie Up.
The Agent's current voice is identical to the female spy's voice pack, voiced by DustyOldRoses.￼
The Agent used to be called Disguiser.
Agent used to have classic Brute's face in 2017
Cloaking and decloaking are loud. Try not to decloak directly next to an enemy, as they may take notice and ensure your demise.
Trickstabbing is far more difficult in TC2. You'll need to imagine an equilateral triangle coming out of the target's back, and aim to stab near the middle.
Sapped buildings take 33% less damage from your attacks unless using the Enforcer. Don't attack a sapped building unless there is any real danger of the Sapper being removed or nobody is near to stop you. A lone sentry can be easily destroyed but a protected or higher-level sentry may be troublesome. A lone dispenser is completely useless but is also a free health/ammo pack for enemies. A lone teleporter can be easily camped but once a power class walks through it can severely harm your team. Always be aware of what you sap, you might not know when it will come in handy.
Don't use the disguise kit when you're near your teammates. An enemy will probably notice that none of your teammates are trying to kill you so you'll start to look suspicious.
Using the Disguise Kit near the end of the round that your team is losing will cause you to still look like you are wielding a weapon during Humiliation. An aware enemy will notice that you do not emit crit-boost particles, however, and may still kill you.
When disguising as a marksman, pretend that you're gonna snipe someone by crouching and walking a bit in the same spot, so if a Mechanic is in front of you, sap his building then backstab him.
A riskier, yet effective tactic when playing agent is to backstab a mechanic tending his buildings and immediately sapping his sentry afterwards. If you're fast enough, you'll be able to take out an entire nest in one fell swoop. Do note that this will only work if the sentry's back is facing towards you... be wary!
The Arsonist is highly dangerous to even the best-equipped Agent. Afterburn from their Flamethrower will show through your Disguise and Invis-Watch's Cloak, signalling to the enemy team that you are a turncoat.
Trickstabs, while effective and often satisfying to pull off, may not always be the best choice for disposing of an enemy. Switch to your Revolver if you find yourself in need of backup.
