The War on Min-Sentries is an ongoing conflict between the Empire and Gunslinger Engineers. The war began on July 8, 2010 when Valve Corporation released the Engineer Update for Team Fortress 2, which added the Gunslinger into the game. Currently, it is unknown whether the War on Mini-Sentries will see any sort of conclusion in the foreseeable future.
The Gunslinger allows Engineers to construct the Mini-Sentry, a cheap 100 metal Sentry Gun replacement that is widely believed to be one of (if not the only) truly unbalanced weapon ever added to Team Fortress 2. The Mini-Sentry deploys in less than three seconds, requires no maintenance, and locks down any and all areas with its 100% accurate auto-aim gun and a 360 degree arc of rotation. In addition, the Engineer gains 25 additional health points just for equipping the weapon. The Gunslinger is problematic in that once the Engineer has plopped the weapon down, his foe’s attention and firepower must now be divided between the belligerent Engineer and his rapidly deploying Mini-Sentry. Combined with the fact that the Engineer can freely fire any of his weapons at you during this time, it is nigh impossible for a foe to escape unscathed from an encounter with a Gunslinger Engineer. As if that wasn’t enough, the Mini-Sentry’s 360-degree auto-aim fire will shut down Scouts, jumping Soldiers, and jumping Demomen with a simple press of a button.
The Empire takes great offense at Gunslinger Engineers. Whenever an enemy Gunslinger Engineer is spotted, Imperials focus all of their efforts in order to make certain that they do not enjoy their heretical experience. Instrumental in this conflict is the Direct Hit for the Soldier, the direct counter to the Mini-Sentry, which can destroy the building in a single hit. The use of the Gunslinger is strictly prohibited within the Empire; Imperials must not give into their hate and instead stand as paragons of all that is just and balanced.
Many battles have been won in hundreds of campaigns, but the War is not over until the Gunslinger and its users are nerfed off the face of the Earth.
