the game without being intentionally attacked by enemy characters. Protocol droids and astromech droids can open special doors. Characters such as Boba Fett and Young Anakin can fit into tight places. Every character, other than the PK Droid, Gonk Droid (whose only ability is that they are never killed by enemies), and Chancellor Palpatine, has a special ability. Unlocked characters can be imported into the game's sequel, Lego Star Wars II: The Original Trilogy, as an extra called "use old save", which costs 250,000 Lego Studs, and can be used in its character creator function. Because the game is based on the Prequel Trilogy (1999, 2002, 2005), Luke Skywalker, Han Solo, Lando Calrissian and other characters from the original Star Wars Trilogy (1977, 1980 and 1983) are not shown, and appear in the sequel Lego Star Wars II: The Original Trilogy. However, if the player unlocks the last level (an episode 4 preview), Darth Vader, a stormtrooper, a rebel trooper and Princess Leia become available. Original trilogy characters Chewbacca, Obi-Wan Kenobi, Yoda, Darth Sidious, C-3PO, and R2-D2 are unlockable in the game since they appear in the prequel trilogy also. Free Play Once a non-vehicle level has been cleared in Story Mode, the player may play through that level again in Free Play Mode. In this mode, players can choose to play through the level with their choice of unlocked characters randomly selected by the program based on their abilities. At any point, the player can rotate instantly between each of the chosen characters to access areas not accessible during the Story Mode and obtain hidden extras. No story cut scenes appear in this mode. Dexter's Diner Dexter's Diner is the area where the player chooses what level to enter, or they can enter the Parking Lot to view any vehicles whose parts they have found and pieced together. The parts to these vehicles are contained in 10 mini-kit canisters which are hidden throughout each level. Battles often take place in the Parking Lot between canon-good and canon-evil characters, such as Jedi and Sith, respectively. At the diner counter, the player may purchase, or enter codes, to unlock extras in exchange for Lego studs they have collected by playing through the levels.
