collect ID cards belonging to characters on the island in order to access certain rooms. Other rooms are completely dark and require night vision goggles to enter. Some buildings contain multiple floors. Jurassic Park supports the Super NES Mouse when playing first-person sequences or operating computer terminals. To win the game, the player must complete several objectives, starting with powering up a computer to re-activate the park's motion sensors. Once activated, the player's short-range motion sensor can detect nearby dinosaurs. Subsequently, the player must determine how raptors are infiltrating the park's visitor center and stop them; prevent raptors from escaping to the mainland on a supply ship; and find the raptors' nests in underground volcanic tunnels and destroy them with a nerve gas bomb. The final objective requires the player to locate a communications center to contact a helicopter, and then reach the helipad to be rescued. The game does not utilize a password feature. The player, therefore, is required to play through the entire game in a single sitting. Development and release Ocean Software, a British video game development company, paid an undisclosed six-figure sum to secure the rights to the Jurassic Park license to develop a game based on the film. Ocean had more developers working on Jurassic Park than any other project up to that point, which led to creative differences; however, Ocean's head of software development, Gary Bracey, said that "with such a great amount of artistic input, this was actually turned to an advantage." The game's designers were J.H. Beard and C. Kerry. Jurassic Park was originally planned for release in August 1993. An early demo with outdated test graphics was unveiled to a disappointed audience at Chicago's Consumer Electronics Show in June 1993. Ocean executives in the U.K. were unaware of the demo's poor graphics, as the demo was developed at Ocean's offices in California. The developers, who were on a tight schedule, did not have time to create a better demo with improved graphics, as doing so could have compromised the game's completion date. The game's final graphics were vastly improved as development continued. During development, Ocean had access to film stills and storyboards from the film. The game uses digitized photographs of the film's characters, as well as a digitized dinosaur image from the film. Ocean claimed the game was the first to utilize high-resolution backdrops. According to Bracey, "Steven Spielberg said
