Resident Evil Revelations places Jill Valentine and Chris Redfield in events between Resident Evil 4 and Resident Evil 5, pursuing the truth about the T-Abyss virus. The story begins aboard the supposedly abandoned cruise ship Queen Zenobia, where confined spaces and scarce ammunition make survival central to its horror. Its journey also reaches the devastated city of Terragrigia and snow-covered mountain locations, contrasting environments while keeping investigation and danger at the fore.
The single-player campaign combines exploration with fights against infected enemies, while the Genesis scanner lets players examine areas and reveal hidden items. The HD edition description also identifies Infernal Mode, which raises the challenge and changes enemy and item placement, and the Wall Blister, a mutated threat linked to the virus. These details give the game a mix of deliberate survival-horror investigation and more demanding combat rather than an action format built only around continuous encounters.
Raid Mode offers a distinct structure: players can tackle missions alone or in online co-op, fighting enemy hordes while leveling characters and earning weapon upgrades. Its added characters, weapons, and skill sets make it a separate, progression-focused way to play alongside the story campaign.
