The script adds a flying saucer that fell to the ground and a small mission to destroy the aliens. The UFO is in the area of Fort Zancudo.
N - start/complete the mission to destroy the aliens (when the mission is activated, you will immediately be teleported to the UFO crash site). J - summon aliens. Alien creatures are armed with railguns, be careful.
Weapons and first-aid kits are scattered around the ship, as well as various garbage, behind which you can hide. On the hill is a police vehicle and two tanks that can be used. And you can also meet one character well-known in the plot, who will silently observe all this. Still, he was right and the aliens really exist!
Installation: Move AlienWar.dll to the Scripts folder. Required: Script Hook V .NET, NativeUI.
