To unlock Roger (and Alex, his palette swap), the player must win Stage 3 with less than 5 points of their health bar left, i.e.

Roger, Kazuya's sub-boss, will not be unlocked when Arcade mode is defeated with Kazuya (since this unlocks Devil/Angel).

There are some exceptions to the statements mentioned above: Unlike the previous game, time records are no longer saved in this mode, an additional Time Attack mode was created specifically for this purpose. Kazuya can be unlocked by clearing Arcade with one of the sub-bosses after all of them have become playable, and Devil/ Angel by clearing Arcade mode with Kazuya. After clearing this mode, the ending is shown and the player's fighter's sub-boss is unlocked.

Stage 8 is against the character's sub-boss, stage 9 is against Kazuya Mishima, and stage 10 is against Devil after Kazuya transforms into him. The first seven stages are randomly selected fights against seven of the other initially available characters, while the last three stages are set. The player fights ten stages, as opposed to nine in the first Tekken game. Only the eight default characters have ending videos completing the game with a sub-boss or Heihachi will go straight to the game's staff roll. When playing the game as Heihachi, the player will face all the sub-bosses, followed by Kazuya Mishima in his Devil outfit as the boss. If the number of rounds setting is a value other than 2, a small number will be added to the right of time record denoting the number of rounds played, for example, 1'23'45 1 if the game was set to 1-round matches. Unlike later games, the same character can have multiple time records in the 16 positions available, whereas in later games, the time records were character-specific. Time records are saved in this mode, with the player entering their initials at the end of the game if a record is broken. Clearing the game without using continues unlocks Heihachi. After defeating Heihachi, the character's ending plays and their sub-boss is unlocked for play. The first seven are against random characters, the eighth is against the character's sub-boss, and the ninth is against Heihachi Mishima, the 'boss' of the game.

In the first installment of the series, the player fights through nine stages.
