Xenonauts: Submerged

"'It has been thirty-five years since the Iceland Incident. With the High Praetor's death, the extra-terrestrial forces attacking Earth fell into comas without the connection to their hive mind. With technology more advanced than anything ever seen before on the Earth, the Xenonauts chose to hand their technology over to neither of the two warring superpowers, but to instead use it to begin their campaign for a united Earth free from prejudice and broken political systems. The vast alien empire has made a handful of attempts upon the planet following their failed invasion, but like the Gaulish Village from Asterix, the Earth has always been able to oppose and defeat them. It has taken decades, but finally, NATO and the Soviet Union have been dissolved and a new United Earth has emerged.""Then, from the oceans of the Earth, something else has emerged.""From beneath the depths, a new evil has awakened. Undreamt horrors from the deepest recesses of a Lovecraftian nightmare rise to the challenge, raiding ships and beaches, stealing resources and destroying supply lines before marching onto land, destroying towns and capturing or killing hundreds of hysterical humans. Terrors that have dwelled within our own oceans, at the edge of human consciousness for eons, are now beginning to resurface. The deep ones are coming.""The Xenonauts have long since been honourably disbanded following their defeats of the alien hordes, but now, equipped with the latest state-of-the-art technologies, they have been called back into action. And you are the one in command of the operation. Launch powerful interceptors and submarines around the world to seek down and destroy alien vehicles. Deploy in combat-hardened Xenonauts armed with weapons built specifically for fighting on land, in the sky, or underwater to defend the planet from these hordes of aquatic monsters, and maybe even uncover the true nature of their plans.""Just be careful when dealing with the eldritch enemies of Earth, and always remember that anything could be lurking in the ocean depths. From the warm corals of the Mediterranean to the impenetrable cold depths of the Artic Ocean, no alien world could be as horrific and deadly as the waters of our own planet, and while you may uncover the answer you're seeking over dozens of aquatic terrains and land attack sites, you may not like it ... and more likely than not, it won't like you either.'""- Official description"Xenonauts: Submerged is a turn-based/real-time strategy game concept by Red-Verse-Writer, a sequel to Goldhawk Interactive's Xenonauts. Similar to the original game being a spiritual successor to the original X-COM: UFO Defence, Xenonauts: Submerged is a spiritual successor to UFO Defence 's sequel, X-COM: Terror from the Deep. Beginning in the year 1993, roughly thirty-five years after the original Iceland Incident that caused the creation of the Xenonauts organisation and fourteen years after the original Xenonauts, the Earth has been protected from alien attacks and a United Earth has been formed. However, while the planet is safe from alien invasion, from the depths of Earth's oceans, Lovecratian horrors begin to emerge, terrorizing shipping routes and ports before launching land-based attacks where they kill and abduct humans for scientific experimentation. With the technology created during the first war against inhuman enemies useless in salt water, the Xenonauts are called back into action to combat the eldritch menace and uncover their motives and where they came from.

Gameplay
The gameplay of Xenonauts: Submerged is similar to its predecessor, with the player in the role of the commander of the clandestine organisation Xenonauts, who must defend the Earth from a invasion of hostile forces that emerge from the oceans of Earth.

Standard Weapons
A new line of manmade weaponry built for fighting underwater, which the Xenonauts begin with and have a unlimited supply of. They are effective against the weakest creatures, but rapidly fall short of newer, stronger ones as the war progresses.


 * Dart Gun: The aquatic equivalent of the Pistol.
 * Harpoon Launcher: The aquatic equivalent of the Assault Rifle.
 * Jet Carbine: The aquatic equivalent of the Shotgun.

 * Guided Aqua-Grenade: The aquatic equivalent of the Frag Grenade.
 * Aqua-Flash Grenade: The aquatic equivalent of the Flashbang.

Aqua-Laser Weapons
The direct upgrades to the standard weaponry and a adaptation of the laser technologies of the first game. They do much more damage than standard weapons, but have smaller clip sizes and require manufacturing. Unlike laser weapons in the first game, the player does not need alien materials to craft them.


 * Aqua-Laser Pistol: The upgrade to the Dart Gun.
 * Aqua-Laser Rifle: The upgrade to the Harpoon Launcher.
 * Aqua-Laser Carbine: The upgrade to the Jet Carbine.

 * Magna-Blast Pack: The aquatic equivalent of the C4.

Particle Weapons
Based on captured enemy weapons, which use various sub-atomic particles, Particle Weapons are the game's equivalent of the alien Plasma Weapons. The player needs alien materials to manufacture them, and they do more damage than Aqua-Laser Weapons. They all also have the same clip sizes as standard weapons.


 * Anode Pistol: The upgrade to the Aqua-Laser Pistol.
 * Ionic Rifle: The upgrade to the Aqua-Laser Rifle.
 * Tau Blaster: The upgrade to the Aqua-Laser Carbine.
 * Muon Laser: The upgrade to the Aqua-Laser Sniper.

 * Particle Disturbance Grenade: The aquatic equivalent of the Electroshock Grenade.

Sonar Weapons
On par with the original war's MAG Weapons, Sonar Weapons are stronger than almost anything the creatures have in their arsenal. They have both increased damage and clip sizes, but are mainly held back by their high monetary and resource cost.


 * Sonic Handgun: The upgrade to the Anode Pistol and the ultimate upgrade to the Dart Gun.
 * Sonic Blaster: The upgrade to the Ionic Rifle and the ultimate upgrade to the Harpoon Launcher.
 * Sound Wave Gun: The upgrade to the Tau Blaster and the ultimate upgrade to the Jet Carbine.

 * Magnetic Pulse-Blast Pack: The upgrade to the Magna-Blast Pack.

MAG Weapons
Available only in land-based missions, MAG Weapons are exactly the same as they were in the original Xenonauts, and will automatically replace a Xenonaut's water-exclusive weaponry during these missions. They are extremely powerful, and primarily show how humanity has a complete advantage over the aquatic aliens on land.
