The player's character is a member of a special law enforcement task force who is trapped in a mansion populated by dangerous mutated creatures. The objective of the game is to uncover the mystery of the mansion and ultimately escape alive. The game's graphics consist of real-time 3D polygonal characters and objects, superimposed over pre-rendered backdrops with fixed camera angles. The player controls the character by pushing the D-pad or analog stick left or right to rotate the character and then move the character forward or backwards by pushing the d-pad up or down.
To fulfill the game's objective, the player uncovers various documents that provide exposition about the game's narrative, as well as clues that help them solve various puzzles within the mansion. Key items are also available that give the player access to other items or new areas. The player can arm their character with weapons to defend themselves from enemies, although the ammunition available for each firearm is limited and the player must learn to conserve the ammunition they have for situations where they will really need it. To restore the character's health, the player uses first-aid sprays or three types of healing herbs that can be mixed together in different combinations for different healing effects. The carrying capacity of the player is limited depending on the character and items that the player does not wish to carry at the moment can be stored into an item box to be retrieved for later use. To save their progress, the player must pick up an ink ribbon and use it on any of the typewriters scattered through key locations in the game. However, the supply of ink ribbons the player can acquire is limited much like the player's ammo and healing supplies. Players will encounter and fight various infected creatures as flesh-eating zombies, undead dogs, giant spiders, and other monsters.
Synopsis
Setting
A series of bizarre murders have occurred on the outskirts of Raccoon City, with signs of cannibalism on the victims' remains. The Raccoon Police Department's Special Tactics And Rescue Service (S.T.A.R.S.) are assigned to investigate the murders. S.T.A.R.S. is divided into two teams: Alpha and Bravo. Bravo Team is sent first, but after contact with them is lost, Alpha Team is sent to investigate their disappearance.
Characters
Players can choose between the two Alpha Team members Chris Redfield or Jill Valentine, each with their own unique differential abilities. Jill has more firepower and possesses a lock-pick that enables her to access areas and items easily, as well as an inventory large enough to hold up to eight items, while Chris has limited firepower but is more durable in terms of taking damage from enemies, and a smaller inventory that can hold only six items.
The game's supporting characters include Barry Burton, Alpha team's weapons expert who provides Jill with additional firepower; Rebecca Chambers, a surviving member of Bravo team who supports Chris with her medical expertise; Albert Wesker, the captain of S.T.A.R.S. and leader of Alpha team; and Brad Vickers, the helicopter pilot who sends transmissions to them as he tries to find them in the helicopter.
The other members of S.T.A.R.S. include Joseph Frost, the sixth member of Alpha team whose sudden death sets the story into motion, Enrico Marini, the leader of Bravo team who gives the player the game's most critical plot twist, Richard Aiken, who gives the player a radio used to receive Brad's transmissions, Kenneth J. Sullivan, a member of Bravo team killed just after Alpha team arrives, and Forest Speyer, whose corpse is found on the balcony by the player.
Story
On July 24, 1998, when a series of bizarre murders occur on the outskirts of the fictional Midwestern town of Raccoon City, the Raccoon City Police Department's S.T.A.R.S. team are assigned to investigate. After contact with Bravo Team is lost, Alpha Team is sent to investigate their disappearance. Alpha Team locates Bravo Team's crashed helicopter and land at the site, where they are suddenly attacked by a pack of monstrous dogs, killing team member Joseph Frost. After Alpha Team's helicopter pilot, Brad Vickers, panics and takes off alone, the remaining members of the team (Chris Redfield, Jill Valentine, Albert Wesker and Barry Burton) are forced to seek refuge in a nearby abandoned mansion.
Depending on which character the player assumes control of, either Chris or Barry are separated from the rest of the team during the chase and do not make it to the mansion. At this point, the team decides to split up to investigate. Over the course of the game, the player character may encounter several members of Bravo Team, including Enrico Marini, the captain of the S.T.A.R.S. Bravo Team, who reveals that one of Alpha Team's members is a traitor before being shot and killed by an unseen assailant. The player character eventually learns that a series of illegal experiments were being undertaken by a clandestine research team under the authority and supervision of biomedical company Umbrella Corporation. The creatures roaming the mansion and its surrounding areas are the results of these experiments, which have exposed the mansion's personnel and various animals and insects to a highly contagious and mutagenic biological agent known as the T-virus.
Eventually, the player character discovers a secret underground laboratory containing Umbrella's experiments. In the lab, the player encounters Wesker, who reveals that he is a double agent working for Umbrella, and plans to use the Tyrant, a giant humanoid supersoldier, to kill the remaining S.T.A.R.S. members. However, in the ensuing confrontation, Wesker is supposedly killed and the player character defeats the Tyrant. After activating the lab's self-destruct system, the player character reaches the heliport and manages to contact Brad for extraction, at which point the player may be confronted by Tyrant one last time. The game features multiple endings depending on the player's actions at key points over the course of the game. In the best ending, the surviving team members escape by helicopter as the mansion self-destructs. In contrast, in the worst possible ending, the mansion remains intact and the player character is the sole survivor.
