Resident Evil 3
Mercenary mode:
Successfully complete the game one time to unlock mercenary
mode and save the "Next Game" file. Start a new game, choose
that saved game, then select mercenary mode. This mode
involves controlling Carlos, Mikhal, or Nikoli from the train
to the starting room with a two minute timer. Killing the
various opponents and rescuing civilians during the journey will
add more time to the clock. A rank and money will be awarded
after the game is completed. The money can be used to purchase
better weapons for the next mercenary mode game.
Epilogues:
Successfully complete the game under the hard difficulty setting
to unlock Epilogues. Epilogues are a short diary description of
each character in the entire Resident Evil series which describes
what happened with that specific person after their adventure.
Getting better ratings can unlock the other epilogues.
There are eight total Epilogues that can be unlocked.
Operation Mad Jackal option:
Successfully complete the game under any difficult setting.
Jill's diary:
To get Jill's Diary (a file), collect all thirty files in the
game in order. Then the first file (Instructions Manual, blue)
will become Jill's Diary.
Barry Burton ending:
The only way to see Barry is if ending B is unlocked. To get
this ending, jump off the bridge when fighting Nemesis Type B.
After the jump off decision, the final area of the game will
take a somewhat different path. You will have to fight off Nicholai
in a chopper. It is recommended that you bring a Magnum and
Grenade Launcher (or Rocket Launcher if it has been found).
You can also choose to negotiate with him.
Barry Burton ending 2:
Jump off the bridge. Play until you reach the room with the
Radar Tracker. Take it, and try to leave the room using the
door you entered. Nicholai will call you. After killing him,
Carlos will enter. After talking with him, leave the room
(do not use the hatch to the Rail Cannon). Turn around and get
in the radar device room again. Carlos and Jill will listen to
a radio call from Barry and the game will continue with the final scenes.
Enhanced Weapons/Ammo:
You can only create enhanced ammo while playing under the hard
difficulty setting. When creating ammo with the reloading tool,
save enough gunpowder to mix up the same type of ammo eight times.
On the eighth time, the game will prompt "Do you want to create
the enhanced ammo?". Select "Yes". This ammo is more powerful,
may have slightly different effects, and once loaded into a
weapon will change it into an "enhanced weapon". You can only
create two types of enhanced ammo: 9mm handgun bullets and shot
gun shells. The only different effects the new bullets have is
that they are far more powerful.
