TYRANIDS STRONGHOLD

Description:
The Tyranids Stronghold is divided to 9 Major Parts, 6 parts are huge bases (including your own) divided by forest & they all enter a single flooded area (water gives you negative cover) & on the waters edges you'll find 3 Critical Locations & 3 Relics. The water is a river stretching from North-West to South-east, on it's beginning & end you'll find a Slag Deposit & a small amount of resistance, while in the middle you'll find a very tough base from where Gargoyles (Tyranid fliers) are made from & they are protecting those 6 Major points.
There are also 6 bases:
Far West - Your base, where you start.
Far North - Ambush Brood (it is from here that Lictors & Raveners are made)
North-East - Artillery Brood (produces Biovores & Zoanthropes)
South-West - Assault Brood (produces Carnifeyes)
From South to South-East to East is a huge Brood, with 3 Hive Spires (Tyranid HQ) with Perfect Link (Hive Spire at Tier 3)

Objectives:
Primary:
-Capture all 3 Critical Locations (which are nerve extensions of the crashed Hiveship) & hold them for 10 minutes (so you could do severe damage to the Hiveship)
-Destroy all 3 Hive Spires with Perfect Link, so the Tyranids would loose their connection to the Hive Mind (damaging the Hiveship does the same thing).
Secondary:
-Destroy Ambush Brood to prevent Tyranids from making Lictors & Raveners.
-Destroy Areal brood to prevent Tyranids from making Gargoyles (fliers).
-Destroy Assault Brood to prevent Tyranids from making Carnifexes & Uberfexes.
-Destroy Artillery Brood to prevent Tyranids from Making Biovores & Zoathropes.
-Destroy both Magma Vents (Tyranid Thermo Plasma Generators) to gain reinforcements (a bit from each one). Like 2 or 3 Squads &a light Vehicle.
-Capture & Control 3 Relics for 10 minutes to prevent Tyranids from making Spore Clusters (Floating Spores that can be deepstriked).
-Kill the Broodlord to prevent the Tyranids from making any more Genestealers.

Story:
The Tyranids influence over this area is so powerful that almost anybody can hear the voice of the Hive Mind echoing their own. It is here that Hive Fleet Kraken first appeared in the Cybius system, when a single Hiveship crashed, revealing rich amounts of resources hidden underwater.

Chats between the Commander & the Hivemind begin when you begin the Stronghold mission, when you attack/destroy the Magma Vents, locating/capturing/holding the Critical Locations, & when reaching the Main Brood & destroying all 3 Hive Spires with Perfect Link.

Tyranids Stronghold Assault:
You see a group of Gaunts running of somewhere & on the cliff, you see the Hive Tyrant, the camera slowly zooms in & then you hear the Hive Mind:
-Aaaah...the prey is approaching...excellent... (the Gaunts start fighting your troops)...come...come to me... (Raveners jump out of the ground behind them)...come to my lair...(Carnifex rushes out & Biovores start shooting from afar)...where my creations shall devourer you whole...
(zooms back to the Hive Tyrant, which as a finalle, does an epic roar)

Hive Mind: Aaaaahhhh... Welcome to the predators den...prey....
