The rooms appear as locked doors in Part II and caves or various buildings in Part III. Within each object room the player must obtain one of the items ostensibly scattered by Biff. These keys are used to unlock the various object rooms throughout each level. At other points the player must use the DeLorean to navigate large chasms that appear on different timelines.Īs the player progresses through the level they obtain keys by killing certain enemies. Some alleyways appear in all three timelines while others appear in one or two but not all three. Scattered and hidden throughout each timeline are Object Rooms (containing objects which must later be returned to other locations) and alleyways used to navigate street to street within the timeline. The player must also collect fuel for the time machine and junk food for extra lives as they progress through each timeline. The player controls Marty and attempts to defeat enemies by jumping on or throwing projectiles at them. To impede his progress, outlaw Buford Tannen has other plans.ġ985A Street Level from part II Street level Before they can return to 1985, Marty must find and return ten more items to their rightful location. Now, with the help from 1955 Doc, Marty must go back in time in order to rescue the present-day Doc with the aged but repaired DeLorean. According to the old letter, Doc has become stranded in the past and must be rescued or else this will start another time-ripple effect.

At the same time, Marty receives a letter from Doc via a courier that was written in 1875 (although 1885 in the film). With Hill Valley in ruins, Marty must now travel to all three periods, then find and return all the items back to their original places in order to retrieve the almanac and destroy it.Īfter Marty returns all items to their rightful places and burns the almanac, lightning strikes the DeLorean and sends Doc back in time, leaving Marty stranded in 1955 once again. This action has caused a disruption in time, and now the space-time continuum is falling apart. To ensure that no one else gets their hands on the almanac, Biff travels through time and collects various items and puts them behind locked doors in three different periods. Over the next three decades, young Biff uses the information to win money on the outcome of each sporting event he bets on, making him the richest and most powerful man in the world by 1985A. When Doc takes Marty to the year 2015 to prevent his future son from committing a crime, old Biff takes the Gray's Sports Almanac and travels back to 1955 and gives the book to his younger self.
