Set shortly after the events of Resident Evil 4, the game follows counter-terrorism agents Jill Valentine and Chris Redfield as they try to uncover the truth behind a bioterrorist organization that plans to infect the Earth's oceans with a virus.

Revelations emphasizes survival, evasion, and exploration over fast-paced combat by providing the player with limited ammunition, health, and movement speed.

The game was a moderate commercial success and received generally positive reviews from critics, who praised its spooky setting, sound direction, and presentation.

[2] To progress through a scenario, the player must complete a number of objectives, ranging from solving puzzles to defeating bosses, collecting keys that open doors to new areas, and reaching a specific point in the game.

O'Brian then orders the pair to track down Jill and Parker after discovering that he had given them false intel regarding their colleagues, and sends two other BSAA agents, Quint Cetcham and Keith "Grinder" Lumley, to investigate the airstrip.

After awakening in separate rooms, Jill and Parker reunite and encounter FBC agent Raymond Vester, who refuses to explain his presence on the ship.

The pair also witness a video from Veltro, who reveal their plan to infect one-fifth of the Earth's oceans with the T-Abyss—a new strain of T-virus—in retaliation to the destruction of their forces in Terragrigia by the FBC.

In the laboratory, they neutralize the virus and are confronted by Lansdale via a video uplink, revealing that he worked with Veltro in the Terragrigia panic to increase the FBC's funding and international influence.

Meanwhile, Parker turns his gun on Jessica after he secretly learned from Raymond that she is a mole for the FBC, prompting her to trigger the ship's self-destruct sequence and escape.

Data recovered by Keith and Quint reveals that Lansdale sank a sister ship within the ruins of Terragrigia to eliminate any incriminating evidence.

[9][10] The team chose to develop the game for the Nintendo 3DS because they felt that its 3D capabilities could produce a "tense, scary experience with a realistic atmosphere that could make players feel like there could be something lurking around every corner.

"[13] The developer's main goal was to bring back the content and horror of the Resident Evil roots, while at the same time trying to modernize the gameplay.

[10] A cruise ship was chosen as the main setting for the game because it could provide claustrophobic corridors and make the player helpless in the middle of the ocean.

[15] Revelations runs on a ported and downsized version of Capcom's proprietary MT Framework engine, which was originally designed for high-definition (HD) games such as Devil May Cry 4 and Lost Planet 2.

[11][16][9] Capcom's previous experience with The Mercenaries 3D helped the development team improve the technical and graphical aspects of the game to a greater extent.

Nevertheless, the developers balanced the gameplay of the game by slowing down the speed of the player movement and by making enemies move in a complex and spooky manner, "as if they're trying to avoid your attack.

"[13] The developers decided to support the Circle Pad Pro accessory as soon as it was conceived because improving the game controls was a major priority.

[20] A short demo, allowing players to control Jill on the game's cruise ship for a brief period,[21] was included with the release of The Mercenaries 3D in the following months.

[34] GameSpot described the game as "a thoroughly successful crossbreeding of old-school chills and new-school action", highlighting its tense atmosphere and slow-paced combat.

[39] IGN reviewer Richard George considered Revelations "a great handheld game, one that not only pushes the boundaries and standards of the Nintendo 3DS but one that recaptures a long-forgotten spirit of a classic franchise.

[1][39][41][42] Eurogamer praised the environments for their lighting and particle effects, while GameSpot credited the highly detailed character models, especially those of Jill and certain monsters.

[40] The sound design was also highlighted, with IGN saying that "Capcom has mastered the ability to play up a soundtrack when appropriate, sometimes completely cutting to isolated noises in order to focus a player on something truly haunting.

[39] Game Informer praised the story for its episodic structure and pacing, but admitted that BSAA agents Quint and Keith are the worst characters in the series' history.

[4] The fact that the game supports the Circle Pad Pro was seen as a valuable feature, as it gives players the ability to move, shoot and control the camera at the same time.

[43] In a mixed review, Edge felt that Revelations features the best and worst of the series' past and present, and criticised its episodic structure for breaking the game's engrossing exploration aspect.

[1][36][40][41] Eurogamer stated that the mode "is a great concept for 3DS" and the game "executes it with conviction" due to its unlockable features, challenge, and replayability.

Awards, the Academy of Interactive Arts & Sciences nominated Revelations for Handheld Game of the Year, but ultimately lost to Paper Mario: Sticker Star.
