Tomb Raider

The Tomb Raider franchise has been heavily related to the Legacy of Kain series from its earliest days, at times competing franchises, before sharing a publisher and ultimately a developer as well. The Legacy of Kain series has been often referenced in Tomb Raider games, particularly in the more recent entries which were developed by Crystal Dynamics and the remainder of the teams that worked on the Legacy of Kain series.

Tomb Raider: Legend
Tomb Raider: Legend is the seventh game in the Tomb Raider franchise and the first to be developed by Crystal Dynamics (previous Tomb Raider games were developed by Core Design). Legend re-unites many of the developmental team that worked on the Legacy of Kain series and features many 'Easter Eggs' and other references to the Legacy of Kain series.

References to Legacy of Kain in Tomb Raider: Legend

 * The Croft Manor (traditionally used as a 'training level') features a portrait of the Human Kain, first seen in Kain's Mausoleum in Legacy of Kain: Defiance.
 * Upon game completion (or through the use of cheats) Lara Croft can wield the Soul Reaver in place of her usual pistols - in game it is treated the same as the 'Excalibur' sword.
 * Several of the symbols used in the Legacy of Kain series are seen subtly hidden throughout Legend - including the symbols of the Sound Glyph, Kain/Kain's empire, Raziel/the Razielim and the skull of the Soul Reaver (as seen in the Balance fragment of the Balance Emblem) - with the outfits 'Goth' (presumably a reference to Nosgoth), 'Goth Lace', 'Sports', 'Sports Green' and 'Snowsuit' all including one or more hidden Legacy of Kain symbols. Daniel Cabuco's former site even included a guide to those in the 'Sports' outfit along with images of Lara Croft in front of a Mural seen in the Fire Forge in Legacy of Kain: Soul Reaver.
 * Legend also features the concept of a legendary blade (in this case Excalibur) that is fractured and later re-assembled much like the Soul Reaver blade in Soul Reaver 2.

Tomb Raider: Anniversary
Tomb Raider: Anniversary is the eighth game in the Tomb Raider franchise and the second to be developed by Crystal Dynamics. A remake of the original Tomb Raider game, Anniversary continued the continuity begun in Tomb Raider: Legend. As with Legend, Anniversary was developed by the remains of the team that worked on the Legacy of Kain series and featured several 'Easter Eggs' and other references to the series.

 * As with Legend, The Croft Manor (traditionally used as a 'training level') still features the portrait of the Human Kain, first seen in Kain's Mausoleum in Legacy of Kain: Defiance.
 * Raziel's clan symbol appears on the chest of the 'Wetsuit' costume - itself a reference to the 'Sola diving suit' from Tomb Raider 2.

Tomb Raider: Underworld
Tomb Raider: Underworld is the ninth game in the Tomb Raider franchise and the third to be developed by Crystal Dynamics, completing the trilogy established by Tomb Raider: Legend and Tomb Raider: Anniversary. As with Legend and Anniversary, Underworld was developed by the remains of the team that worked on the Legacy of Kain series and featured several 'Easter Eggs' and other references to the series.

References to Legacy of Kain in Tomb Raider: Underworld

 * As with Anniversary and Legend, The Croft Manor (traditionally used as a 'training level') still features a portrait of the Human Kain, first seen in Kain's Mausoleum in Legacy of Kain: Defiance.
 * Underworld's story features Lara visiting several mythological Underworld locations; though they are depicted literally as sealed underground locations rather than a separate plane of existence.
 * Several enemy variants seem similar to those in the Legacy of Kain series, with many appearing to derive from the same mythological concepts; although treated in a much more 'straightforward' fashion than Legacy of Kain enemies. These include "Giant spiders", the Octopus/Squid-like "Kraken" (which cannot be harmed by conventional means); perhaps most similar are the "Thrall" variant enemies - undead enemies raised by the liquid "etir" and having a notably similar 'decayed humanoid' appearance to the Legacy of Kain thralls.
 * The 'Legendary Blade' concept returns as Excalibur (previously assembled from fractured pieces in Legend) makes a brief appearance in the final cutscene. A different 'Legendary weapon' - Thor's Hammer - can be collected and used in game; its attacks are similar to those used for Excalibur and the Soul Reaver in Legend.
 * The end credits of Underworld begin with the dedication "For Kyle"; referring to the tragic death of developer Kyle Mannerberg who passed away around a year before the release of Underworld. Along with being credited as the lead level designer of Underworld, Kyle was one of the staff originally given custodianship of the Legacy of Kain series after the departure of Amy Hennig.''

Lara Croft and the Guardian of Light
'''"Meanwhile, in another World...and kind of in the past..."

- Raziel and Kain Character Pack introduction '''

Lara Croft and the Guardian of Light is an arcade-style video game developed by Crystal Dynamics. It is the tenth game in the Tomb Raider franchise (despite officially not being considered part of the franchise proper) and the fourth game developed by Crystal Dynamics. Significantly, Guardian of Light featured Downloadable content (DLC) that allowed Raziel and Kain to be used as playable characters for the first time since Defiance.

Guardian of Light is a fixed-camera 3D platform viewpoint action video game developed by Crystal Dynamics and published by Square Enix Europe for the PC, PlayStation Network, Xbox Live Arcade and the iOS as part of the Tomb Raider series (though it does not bear the "Tomb Radier" brand name and is not considered part of the franchise proper, fitting in between the continuity of Crystal Dynamics first Tomb Raider trilogy and the upcoming reboot). The game was made available only for digital download on 18 August 2010. Unlike previous games in the series which were third person adventure games, Guardian of light is an isometric based arcade shooter with a heavy emphasis on cooperative gameplay.

Downloadable content (DLC) was released for Guardian of Light between October and December 2010, including a "Raziel and Kain Character Pack", which replaced the main playable characters (Lara Croft and Totec) with Raziel and Kain respectively. Whilst In this mode, the dialogue between characters was replaced by excerpts from the Legacy of Kain series edited into a humorous storyline.

Plot
Raziel and Kain accidently release the dark god Xolotl who flees his prison to escape to the outside world. Raziel and Kain give chase in a desperate attempt to stop him before the sun rises. After taking different routes on several occasions, Raziel and Kain finally confront Xolotl as the sun rises and Kain personally finishes the dark lord.

Rise of the Tomb Raider
Rise of the Tomb Raider is the eleventh game in the main Tomb Raider Franchise and the second main game in the series since the 2013 reboot (itself the second reboot of the series). Rise was developed by Crystal Dynamics and the remains of the team that worked on Legacy of Kain: Defiance in 2003. Notably Rise featured the return of Legacy of Kain series Easter eggs after a five year absence.

References to Legacy of Kain in Rise of The Tomb Raider
After a number of Easter eggs and references in the previous continuity trilogy of Tomb Raider: Legend, Tomb Raider: Anniversary and Tomb Raider: Underworld - and guest appearances by Raziel and Kain in Downloadable content for the spin-off Lara Croft and the Guardian of Light - the next titles in the Tomb Raider franchise rebooted the series, but neither the 2013 reboot (titled simply "Tomb Raider") or the spin-off Lara Croft and the Temple of Osiris made any mention of the Legacy of Kain series.

The 2015 sequel Rise of the Tomb Raider returned to making references, with the Soul Reaver blade appearing in a secret area in the 'Tomb of the Prophet'. Patterns apparently based upon the clan symbols were also featured in some places.
