The Vortigaunt, known as Alien Slave or Xen Slave, is a boss in Slender Fortress.
Vortigaunts are a fictional alien race in the Half-Life series by Valve Corporation. In Half-Life and its three expansions, Vortigaunts are frequently encountered by the player as hostile non-player characters. The Vortigaunts are depicted in Half-Life as being an enslaved race in an alternate dimension called Xen, subservient to a large Xen creature called the Nihilanth, which itself is a slave to undisclosed masters. In Half-Life 2, the Vortigaunts have broken free of their slavery, and actively assist the player and other humans in resisting the Combine occupation of Earth.
Vortigaunts are shown as a very communal and cultural race, believing in a force that binds the fabric of the universe and each Vortigaunt together, as well as producing a tradition of poetry and music. Vortigaunts also display the ability to summon and command energy without the need for technology. This ability is used for various activities, such as a means of attack, powering electrical equipment, and healing.
In Slender Fortress Edit
The Vortigaunt acts like Shock Trooper, but without Shockroach, and it's a hit and run. This NPC is a ranged attacker, it will attack using electric beams that come out from their hands. Vortigaunts have two modes of attack: an energy attack in which they fire powerful green lightning-like energy beams that require a vulnerable period of "charging-up" before being unleashed, and when close to opponents, a rapid and powerful claw attack.
