Two centuries after the events of Blood Omen, Kain had built a vampire army, and led them south to conquer Nosgoth. However, outside of Meridian - Nosgoth's capital city - Kain's army was defeated by another. The Sarafan Lord, a mysterious and powerful warlord, had revived the long-defunct Sarafan order to battle the vampires. Kain was beaten in combat by the Sarafan Lord and left for dead.
Kain survived - just barely. Another two centuries passed before he awoke from his injury-induced coma, but although he had kept his life, he had lost the Soul Reaver. With the help of the vampires who had protected him during his recovery, Kain set about reclaiming the sword, continuing his ascent to power, and taking his revenge on the Sarafan Lord. Along the way, he would learn about the Hylden - the race cryptically mentioned by Kain in Soul Reaver 2 - and fight traitorous vampires who had sided with the Sarafan for personal gain.
The game is an Action/Adventure set in the third person perspective. The entire
game revolves around a simple premise: flip a switch, walk through doors, move
crates, do glyph puzzles, and kill people to obtain the vital blood Kain needs
Legacy of Kain vampires evolve over time, and the curse of vampirism manifests differently in every individual, giving them various supernatural abilities. In Blood Omen 2, these abilities are known as 'Dark Gifts'. Kain's personal Dark Gift is 'Mist', the ability to assume an insubstantial form when immersed in clouds of fog or mist. He also possesses 'Fury', the ability to unleash a powerful attack when sufficiently enraged. Though he starts with only his own evolutionary traits, Kain can obtain and use (to a lesser extent) the abilities of the traitorous vampires who have sided with the Sarafan upon defeating them and 'absorbing their veins'. Each Dark Gift has a symbol which is visible in their respective recipient's health display in the interface during the boss battle with them. The Dark Gifts and their inherent benefactors are listed here.
One of the two initial Dark Gifts; when Kain is standing in mist he is able to assume a mist form, making him near invisible, unless he moves directly in front of an enemy. While in mist form, Kain moves silently, and is able to sneak up on and dispatch enemies with a particularly gory stealth attack. The attack varies depending on the weapon Kain is carrying at the time. When a skull appears above an enemy's head, a stealth attack can be employed.
The second of the two initial Dark Gifts; in combat this allows Kain to employ a single strike at double his normal strength. This particular power is fueled by Kain's 'Rage Bar'. When Kain starts to glow red, the Fury attack can be employed.
Allows Kain to leap further than humanly possible. When the gift is activated, Kain tenses for the jump, and a ghost image of his form appears. This image shows where Kain will jump to. When the ghost image adopts a purple hue, the jump can be made by pressing the button again. If Kain jumps into an enemy, the ghost image turns red, and an attack is executed as Kain jumps.
Allows Kain to take control of a non-hostile character. When the gift is activated, a target appears. Once it is moved over a civilian character, the button can be pressed again, and the player then assumes control over that character. While under Kain's control the character can be moved, and can activate switches etc, but cannot attack and cannot stray beyond a certain range of Kain.
Allows Kain to execute a flurry of attacks against a single enemy, culminating in a slow motion scene where the enemy is seen flying through the air after Kain's final blow. Like Fury, this attack is fueled by the Rage Bar.
Allows Kain to manipulate certain objects using his mind, particularly the special telekinetic emblems which act as switches during the latter portion of the game. This gift is targeted, much like Charm. It can also be used to attack enemies. There is no boss battle to gain this gift; it is acquired after Kain meets the Seer in the canyons.
The final Dark Gift. This power allows Kain to set his enemies on fire using only his mind, causing instant death to the targeted foe. The sole enemy powerful enough to withstand this unstoppable attack is the Sarafan Lord, the final boss of the game. This gift, like Fury and Berserk, is combat only and is fueled by a full Rage Bar.
While not a Dark Gift as such, this weapon is gained during the battle with the Sarafan Lord. It also acts as his interface symbol throughout the fight. It is the strongest weapon in the game, and is unbreakable. It can also be gained, along with Kain's Iron Armour from Blood Omen: Legacy of Kain, at the start of a new game following the entry of a cheat code at the Main Menu.
