In 2010, Square Enix released The 3rd Birthday, a bold reimagining of the beloved Parasite Eve series. Combining elements of third-person shooting, RPG mechanics, and a gripping sci-fi narrative, this PSP-exclusive title gave fans a fresh yet familiar dive into the chaotic life of Aya Brea. With its emotional story, intense combat, and haunting atmosphere, The 3rd Birthday stands out as a unique entry in gaming history, even years after its release.
The Enigmatic Storyline: Aya Brea’s New Fight
Set in a near-future Manhattan ravaged by an apocalyptic phenomenon called “The Twisted,” The 3rd Birthday follows Aya Brea, a woman with extraordinary abilities and a mysterious, fragmented past. After awakening in the ruins of the city, Aya becomes part of the Counter Twisted Investigation (CTI) team, a group dedicated to eradicating the monstrous Twisted and uncovering the truth behind their emergence.
Aya wields a groundbreaking ability called “Overdive,” allowing her consciousness to leap into the bodies of other operatives during missions. This power not only gives her a tactical advantage on the battlefield but also ties into the deeply personal and emotional core of the story.
As Aya delves deeper into the twisted timeline, she begins to piece together shocking revelations about herself, her forgotten memories, and the nature of the Twisted. Themes of identity, sacrifice, and redemption permeate the narrative, culminating in a series of jaw-dropping twists that challenge everything you thought you knew about Aya Brea and the Parasite Eve universe.

The Battle for Humanity: Innovative Combat Mechanics
The 3rd Birthday redefines combat with its dynamic blend of third-person shooting and tactical strategy. The Overdive system adds a unique layer to battles, allowing Aya to:
- Leap Between Allies: Overdive into nearby soldiers to reposition, gain a fresh perspective, or evade attacks.
- Exploit Weak Points: Build up energy to perform devastating Overdive Kills, which deal massive damage to enemies.
- Customize Loadouts: Equip Aya with a variety of weapons, from handguns and rifles to grenades and specialized gear.
Combat is fast-paced yet requires strategy, as players must balance aggressive attacks with positioning and resource management. Aya’s vulnerability adds tension to every encounter, making each victory hard-earned and satisfying.

Characters That Drive the Drama
The cast of The 3rd Birthday is a compelling mix of allies and antagonists, each adding depth to Aya’s journey:
- Aya Brea: The protagonist grapples with amnesia, her role in the CTI, and the weight of her unique powers. Her quiet strength and vulnerability make her a relatable and tragic heroine.
- Kyle Madigan: A mysterious figure from Aya’s past, Kyle’s motives and loyalties are shrouded in ambiguity.
- Hyde Bohr: The CTI’s enigmatic leader, whose intentions are as questionable as his methods.
- Kunihiko Maeda: A scientist and a returning character from the original Parasite Eve, Maeda provides crucial insights into the Twisted and Aya’s unique abilities, adding a layer of continuity and expertise to the narrative.
- The Twisted: The grotesque antagonists of the game, these creatures are as terrifying as they are fascinating, representing humanity’s greatest fears and secrets.
Each character plays a role in the unfolding mystery, challenging Aya—and players—to question the nature of truth and trust.
