Resident Evil 3

Successfully complete the game under the easy difficulty setting with any rank better than F to unlock Jill's costume from the original Resident Evil and Regina's costume from Dino Crisis. To unlock three additional costumes, successfully complete the game under the hard difficulty setting with a rank of A. This will unlock police miniskirt, disco, and biker costumes.

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.

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.

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.

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.

Get to the alley behind the bar. Walk out into the alleyway until you see stairs. Nemesis will appear with a rocket launcher, but before he can shoot a second Nemesis will shoot at you but will hit the first Nemesis and knock him down.

When you first get to the trolley, Carlos will give you a "fanny" pack. After you finish the game, you will keep those additional two slots in the game.

You can meet Carlos at the top floor of the newspaper building instead of the restaurant when you first come out of the area after you fought the first Licker. You will hear Carlos taking out a few zombies. Ignore that and go to Jill's left. Enter the door at that location. You will now be at the alley directly behind the restaurant. From here, make your way to the newspaper office. After meeting Carlos, Nemesis appears. You will get to make a choice to "Jump out the window", or "Hide in the back". Note: To get the green gem, go back to the restaurant and go down the ladder. Then, check the police officer down there. He should have it.

When you gain control of Carlos, beware of the Aqua Hunters that are in the Artificial Environment tank. When fighting them, keep firing your weapon as much as possible. When they grab you, tap on the buttons as much as you can or they will eat you whole.

Kill Nemesis seven times in your first game and he will drop the assault rifle. Kill him seven times in your second game he will drop an infinite ammo case.
