A video game for the XBOX was released in 2002, featuring all the Buffy the Vampire Slayer cast save Sarah Michelle Gellar, taking place between the third season episodes "Revelations" and "Lover's Walk" (the gang knows Angel's back, but Xander and Cordelia are still together). It centers on yet another bid to revive The Master, with Spike being forced to help because Dru is held hostage. It was followed by a sequel, Chaos Bleeds, which has slain foes Back from the Dead as Ethan Rayne challenges The First Evil to a contest, using The Scoobies as his champions in a bid to become a chaotic god.
Between the two games we find the following tropes.
Back from the Dead: The main plot of the first game is to do this with The Master, and the second game has numerous antagonists pull this.
Borrowed Catchphrase: In the alternate dimension Buffy has to find the other playable characters. Turns out Faith is chilling in a bank vault waiting to be rescued, and will use Willow's "Bored now" as Buffy does so. In this instance there no ominous foreshadowing, fight or Flaying Alive, Faith just wants out.
Breakable Weapons: Most weapons have limited durability. Wooden weapons can be broken down into stakes, and stakes will eventually break as well.
"A sparkly thingy, to add to my collection of sparkly thingies".
Badass Normal: Xander is easily as capable fighter as Buffy, Faith or Spike.
Book End: The central villains of the two games are respectively the key antagonists from the show's first and final seasons: the Master in the first game, and the First Evil in Chaos Bleeds.
Call Forward: Loads and loads of them, from Spike flipping the V at Angel to Xander's love spell to Buffy freaking at the idea her mother will be raised from the dead to Faith borrowing Willow's bored nowCatch Phrase. When Cordelia goes on about Angel being evil Angel will address this, commenting on shouldering the crimes he had committed and trying to work towards redemption. This would be shown in greater detail when the two characters become the leads in Angel's show. Part of Spike's Heel-Face Turn is also due to him being as against the game's Big Bad's plans as he was against Angelus unleashing Acathla to destroy the world.
Continuity Nod: Xander makes fun of Drusilla having the hots for him. Spike angrily replies it was due to the love spell he created when he wanted to get back at Cordelia.
When Angel becomes involved all the Scoobies question whether he might go evil again. When The Master possesses him they discuss trying to restore Angel, or the possibility Buffy might have to kill him.
When Spike makes his appearance Buffy is furious he went back on the deal they had in Becoming..
Demonic Possession: The demons Spike works for does this to Dru to force his cooperation, and The Master takes control of Angel as a host. The Wangst over the idea that Buffy might kill him is surprisingly toned down.
Elite Mooks: Common garden variety vampires are surprisingly dangerous when compared to demons.
Enemy Chatter: And thanks to the limited voice samples it can get real old real fast. A quick application of pine to a vampire's chest however will mean you only have to hear Buffy yap.
Enemy Mine: Spike finally gets fed up with working for the vamps trying to bring back The Master and turns to the Scoobies to offer aid in exchange for releasing Dru.
Evil Twin: Buffy has to fight one in the first game, and Anya, Tara and Ripper become this in the second.
Final Death: At both ends of the spectrum. Some enemies (vampires for example) have to be staked or burned to be disposed on. Likewise, Buffy can survive with no energy, she dies from being bitten (vampires, spiders), slashed, some special death move, or long falls.
Gargle Blaster: The mother of them all: Faith finds hellfire vials (think Molotov cocktails) and muses about drinking it like beer.
The first level of the docks requires holy water. Unless you think to smash open the large crates to find a font you're kind of stuck. Buffy even lampshades being able to find it.
He Knows About Timed Hits: The beginning of the game has Giles put Buffy through basic training. Chaos Bleeds has the characters fend off an attack on The Magic Shop, with Giles, Anya, Tara and Buffy explaining the basics to the four main characters (save Faith, who plays the same as Buffy).
Opening Narration: The first video game expands on the one given above, retaining Giles as a narrator:
In a time when the world was young and demons ran unfettered across the face of the earth. The powers that be chose a young woman, one girl in all the world to combat the forces of darkness. Upon her death, the power passed to another and another. Down over the millennia with each inheriting the power of her predecessor. The power of the Slayer.
Sniper Crossbow: Buffy can zoom in on unaware vampires and score a One-Hit Kill from afar if she can listen to their heartbeat and nail them.
Standard Status Effects: As you progress through the game vampires will have this ability to stun Buffy, which is kinda like the thrall powerful vampires like The Master and Drusilla have. Some demons have something similar.
Buffy: While everyone bones up on sigils and resurrection, I'll head over to the mansion and bone up on Angel... That so did not come out right.
The Other Darrin: Giselle Loren performs the voice of Buffy (and Anya in Chaos Bleeds), where Kari Wahlgren fills in for Alyson Hannigan in the second game.
The Voiceless: Strangely, Drusilla does not have a single line of dialogue. The demon possessing her does though, and he's not about to take any of Spike's lip.
Title Sequence: After Giles gives a brief rundown of the plot we get a remade game version of the titles, although they goof in having the traditional Power Walk and shot of Buffy switched around. Averted in Chaos Bleeds, which goes directly to a shot of Sarah Michelle Gellar.
Trick Arrow: Buffy can trick out her crossbow bolts with Hellfire or Holy Water.
Wake-Up Call Boss: Spike is the first major boss fight in the game. This is the first fight that really forces you to conserve your health elixirs and focus on tactics and Slayer powers. You might say that he is a... DifficultySpike.
Who Writes This Crap?!: Spike begins reading out an incantation to summon a demon, before turning to the vampires he's working for and asks who writes this dross.
Written-In Absence: Oz does not appear in the first game even though it took place while he was still a member of the Scooby gang. It's Handwaved by Willow saying he's out of town with the rest of Dingos Ate My Baby at a gig.
