The default title screen is a still image of Leon and Ashley. After beating the game once, the screen will change to a scrolling panoramic image of the village centre. The joystick can be pushed to change the scroll speed and direction of the image. After beating the game, there is no way to change the image back to the default one.
Players can restart the game after a completion with all their current equipment. The Merchant will also always have his full list of items and tune ups on sale as well as any extra weapons the player has unlocked.
Unlocked by beating the game once on normal mode, players now have the option of starting a new game (not a new round) on this difficulty setting. This serves as the game's hardest mode. Enemies take and deal more damage and most ganados do not hesitate to attack.
Extra weapons are only usable in completed game files.
|Matilda||Beat the main game once.|
|Infinite Launcher||Beat the main game once.|
|Handcannon||Obtain a 5 star rank with all characters on all stages in the Mercenaries minigame.|
|Chicago Typewriter||Clearing the Assignment Ada mini-game unlocks this for the maingame in the Gamecube version, but unlocks it for Separate Ways in all other versions. Beating Separate Ways will then unlock it for the main game.|
|P.R.L. 412||Beat Professional mode. This weapon is not in the Gamecube version.|
There are two sets of unlockable costumes. Players are given the option to select them when starting a new game or round. When selected, all costumes change based on the set, there is no option to change each character's costume individually or during mid game.
If the player has kept the tactical vest and chooses the Default costume set, Leon will have the vest on and not his jacket.
Set "Special 1" is unlocked by completing the game.
Leon will appear in a R.P.D. uniform. This is an updated version of his outfit from Resident Evil 2. The R.P.D. outfit has the same effects as the Tactical Vest (shaving 30% of all damage taken). The tactical vest itself can also be worn to stop 60% of damage. This effect is not present in the Wii and HD re-release versions.
Ashley will appear in a white and red-trimmed pop star outfit.
Ada will wear a clad in black combat gear. It also has the butterfly icon on her shoulder that is also present on her default dress. This is the same costume she wears during the Assignment Ada mini game.
"Special 2" is not available in the Gamecube version. For all other version it is unlocked by completing Separate Ways.
Leon S. Kennedy will appear as a gangster outfit complete with a red tie, fedora, gloves, and a white scarf. This will also reskin his knife into a switchblade. This will also change the appearance of the Chicago Typewriter; the magazine will be changed to a ammo drum. Special animations are given to Leon when reloading the Chicago Typewriter: reloading results in Leon adjusting his hat. Reloading a four times in a row results in Leon performing a trick where he throws his hat up and catches it. The gangster outfit reduces enemy damage by 60% and when combined with the Tactical Vest, reduces 90% damage. Again the effect is not present in the Wii and HD re-release versions.
Ashley Graham appears in a complete medieval suit of armor. Only part of her face can be seen normally. When aiming a gun at her the face protection lowers itself. The suit makes her invincible to every enemy attack. She also cannot be picked up by enemies as they will immediately drop her. When Leon catches Ashley from a fall, he will flinch from the massive weight.
All extra game modes are unlocked by completing the game once. They are;
The Mercenaries - An arcade style minigame where the player can play as different characters to kill enemies within a time limit and aim for a high score.
Assignment: Ada - A short non-canon scenario where the player controls Ada and must collect plaga samples. She has her own starting equipment and it takes place on the beginning parts of the island.
Separate Ways - A large 5 chapter canon scenario that shows Ada's actions during the maingame. The player can save during the game and visit the Merchant.
An option that allowed players to rewatch cutscenes. All the maingame scenes are added once the game is complete and then, all the Separate Ways scenes are added once that game mode is completed. This is not available in the Gamecube version.
Ada's Report is a short series of video reports by Ada. There are five and each one is unlocked by completing a chapter of Separate Ways.
