No one expected our last stand in the invasion to be at a quiet farm house, especially Them.
— Invasion Update
Probed is a community-made King of the Hill map created for and won the 2014 TF2Maps.net Major Mapping Contest #11, "Mercs vs. Aliens". It was included in the game with the Invasion Community Update.
Two identical paths separated from each other conjoin together at a central point. Along the paths are balconies connected via bridges providing defensive positions for Snipers and Engineers.
To win, your team must hold the lone Capture Point for three minutes like any standard King of the Hill map, while avoiding the alien UFO that periodically flies over the point to abduct unaware players.
- Barn Spawns: Outside the spawns are three pathways to choose from. All three lead to the same pathway to the control point.
- Rural Pathways: Over the dual pathways to the control points is a catwalk for height advantage.
- Grain Silo Control Point: At the control point is a second floor structure for Sniper advantage. The grain silo in front of the point is open on both pathways.
- Alien UFO: Periodically, a saucer will fly over the Control Point and activate its tractor beam, sucking any players near the point inside. Speed is increased inside the craft; however, all players will begin taking damage due to the alien craft's toxic atmosphere. On both sides of the craft are corresponding team Teleporters that will return players to their team's side of the capture point. Upon exiting, the player is restored to full health and given a few seconds of ÜberCharge and mini-crits.

- As spawning inside the UFO counts as being freshly respawned, any dropped weapons picked up by the player will instantly become discarded once the player enters the UFO.
- Alien UFOs will sometimes fly around out of bounds and abduct wooden cows that were first seen on 2Fort.
- To the right of the BLU Base in the background, there is a scarecrow wearing An Extraordinary Abundance of Tinge painted Ghastly Gibus.
- On the roof of the structure in front of the RED Base, there is a small train. This is a reference to the map Trainsawlaser, which was another map made by UEAKCrash.
- There is a hidden room that can be found with a link to UEAKCrash's YouTube channel as well as a poster referencing his name and a Teddy Roosebelt with a bed near the Control point. Sometimes the Teddy Roosebelt moves slightly.
- There is also a Map Maker's Medallion and a Spycrab seen in the room as well as a Sawblade and tiny Train underneath a bed. The train and Sawblade are another reference to Trainsawlaser.
- There is a circular portrait on the wall of FissionMetroid101's avatar, who made particle effects for Probed, Watergate, and Trainsawlaser.
- In each team's spawn, there is a hidden Alien shattered in a side room not enterable by the player.
