The first game in the popular God of War franchise, released for the PlayStation 2 in 2005.The player controls the protagonist Kratos, a Spartan warrior who serves the Olympian Gods. The goddess Athena tasks Kratos with killing Ares, the God of War, who is responsible for Kratos accidentally killing his family. As Ares besieges Athens out of hatred for Athena, Kratos embarks on a quest to find the one object capable of stopping the god: the legendary Pandora's Box.
God of War contains examples of the following tropes:
Accidental Murder: Kratos accidentally killed his wife and daughter while attacking a village of Athena's worshippers under Ares' orders; Ares in fact orchestrated the event, believing that it would free Kratos to be the perfect warrior.
The Atoner/Redemption Quest: Subverted to a point; Subverted to a point. Kratos may be on a Redemption Quest, but it's only because he wants to be able to sleep at night without being assaulted by memories of the awful deeds he has committed in the past, including murdering his own wife and child. He has no qualms about slaughtering just about everybody he encounters, either.
Awesome, but Impractical: Rage of the Gods. It grants Kratos invulnerability and increases his damage. However, it takes a long time to charge. And even when you do fill it up, it's best just to save it for the nearest boss fight, because once it's on, you can't turn it off.
Come Back to Bed, Honey: The two women whom Kratos slept with on his way to Athens ask him to stay "just a bit longer."
The Creepy Undertaker: The Grave Digger, who nonchalantly digs a grave as Athens is falling apart around him.
Deal with the Devil: Kratos made one with Ares to serve him in exchange for the strength to defeat his enemies in the past. He ditched Ares after the latter duped him into killing his family in an Unstoppable Rage.
Degraded Boss: Gorgons. Medusa serves as the introduction to the enemy type as well as a demonstration of how to perform a special grab kill, but every Gorgon you meet from that point on is not only a standard enemy, but stronger than she was. Even the ones you meet just a few minutes later.
Early-Installment Weirdness: Most of the Gods have been redesigned after this game (Poseidon was originaly a bald old guy, Hades had a demon face, etc).
Escort Mission: Twisted; at one point, Kratos needs to push a cage containing an Athenian soldier up an enemy-infested ramp. Of course, he's only protecting him in order to burn him alive at the top of the ramp and move on in the temple. He pleads for his life the whole way up.
Exact Words: Athena promised that Kratos would be forgiven for his sins if he killed Ares. She never said he would be free of his Bad Dreams.
Fighting Down Memory Lane: During his final confrontation with Ares, after direct combat has failed, he sucks Kratos into some kind of mental plane, where he forces him to relieve your most defining moment - the day he unwittingly murdered his own family. Or at least, he tries - he has to fight off a horde of 'clone' Kratoses while protecting your family. Fail, and Kratos will simply collapse with a moan of "No... not again..."
Fission Mailed: After a long quest to retrieve Pandora's box, Ares impales Kratos with a giant slab of wood, and Kratos gets sent to Hades. Of course, this doesn't stop him in the least.
Heads I Win, Tails You Lose: The second phase of the final battle has Kratos protecting his family from clones of him. If he fails, the family dies, Game Over. If he wins... Ares takes his blades and rams them both into his family anyway.
Late to the Tragedy: Kratos can find several journal passages from the architect who constructed Pandora's Temple. They don't serve to forward the plot at all, but it's very interesting nonetheless to watch him design the temple, slowly go mad, kill his sons, turn their skulls into keys you use to unlock doors, and eventually pull a murder-suicide on his wife.
Non-Standard Game Over: During the final battle in the first game, Kratos is hurled back to the moment he killed his family, only to find them alive... whereupon Ares conjures up an army of Kratos clones. The family has their own health bar in the following battle; should it run out, a cutscene starts, showing Kratos collapsing in abject despair and sorrow, murmuring, "Not again..." The Kratos clones then gang up and chop him apart.
"Well Done, Son" Guy: Revealed towards the end to be Ares's motive. He shouts to the heavens of his deeds, asking why Zeus favors Athena.
