creatures roaming its halls. The player character eventually learns that a series of illegal experiments were being undertaken by a clandestine research team under the 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. The player character may also encounter several members of Bravo Team, including Enrico Marini, who reveals that one of Alpha Team's members is a traitor before being shot and killed by an unseen assailant. 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. The best ending sees that the player character saves their partner (Rebecca Chambers for Chris's campaign, and Barry for Jill's campaign) as well as a team member imprisoned in the lab (Jill for Chris's campaign, and vice versa). If at least the partner survives, the Tyrant is defeated and the mansion destroyed, otherwise the mansion remains intact and the Tyrant remains loose in the forest if the partner or team member is left to permanently die. Development Design Resident Evil was created by a team of staff members who would later become part of Capcom Production Studio 4. The inspiration for Resident Evil was the earlier Capcom horror game Sweet Home (1989). Shinji Mikami was commissioned to make a game set in a haunted mansion like Sweet Home, and early on, the game was intended to be a remake of Sweet Home. The project was proposed by Sweet Home creator Tokuro Fujiwara, who was Mikami's mentor and served as the game's producer. Fujiwara said the "basic premise was that I’d be able to do the things that I wasn’t able to include" in Sweet
