Difficulty is a choice players are prompted to choose before starting the main game or sometimes side games. Usually a “Normal” difficulty represents the standard difficulty and the way the game is meant to be played and experienced.


Difficulty choices weren't formally implemented right away or used a standard across titles for a while.

The first Resident Evil did not have hard mode, so Director's Cut was developed to further challenge players.

Resident Evil 2’s original Japan release was found to be too difficult so a regular and a rebalanced “easier” setting called “USA Mode” was added to later versions.

Resident Evil 0, the GameCube remake of Resident Evil, Resident Evil Survivor, and Resident Evil Dead Aim all used a straightforward method of re-calculating numbers from picks up for ink ribbons and ammo to damage taken/given rather than rearranging item placement or event.

Resident Evil 4 and onwards most games difficulty worked in tandem with the Rank mechanic to dictate changes, and again mostly not changing item placement or events. Resident Evil 5 and onwards uses more standard "Easy/Normal/Hard" settings seen in gaming in general.


Resident Evil (1996)

  • Very Easy (REmake)
  • Easy
  • Normal
  • Hard (REmake)

Resident Evil 2 (1998)


  • Leon S. Kennedy and Claire will start out with an additional 120 HP, more gun bullets and three First Aid Sprays once they reach the Item Box.
  • The only other difference is that when you use the Ink Ribbon to save your progress, it will be colored white versus being blue or red.

In Resident Evil 2, Nightmare Mode and Expert Mode are available only for the Dreamcast And Windows Ports. Although the Rookie Mode was featured in the Gamecube and PlayStation versions, Nightmare Mode and Expert Mode are missing for unknown reasons. In this mode, enemies will cause a lot more damage, ammo and health items will become a lot more scarce, and usually, with certain monsters, your health can be taken from Fine to Danger in one hit. This happens more often with the Lickers.

Resident Evil 3: Nemesis

Easy: In Resident Evil 3: Nemesis, Jill Valentine will starts with a First Aid Kit, an Assault Rifle and two clips of Assault Rifle Ammo. Also, all weapons are available at the Item Box (except the Grenade Launcher, Gatling Gun and Rocket Launcher). Ink Ribbons are also affected; their amount is infinite, allowing the player to save as much as they want. However, Special Weapons parts (which players can obtain by defeating the Nemesis-T Type) are not available.

Hard: In Resident Evil 3, Jill will start with only a Handgun and the Reloading Tool. In the Item box, only the Knife is available. However, Special Weapons are available after collecting parts obtained by defeating the Nemesis-T Type. There are only 8 inventory slots (but after Carlos Oliveira gives you the "Suspender", there will be 10 slots). Some other items are also obtainable by defeating Nemesis.

Resident Evil CODE:Veronica

Resident Evil: Outbreak

In Resident Evil Outbreak, it is unlocked after completing the Decisions, Decisions scenario. 2000 points are needed to purchase it. In Outbreak File #2, It is unlocked after completing the "end of the road" for the same price.

Very Hard:  It's unlocked in both titles by completing all five main scenarios in Hard mode.

  • Items are very scarce, and most of them will be replaced by key items.
  • Enemies are at their strongest; players will often find themselves run out of ammunition should they engage enemies in the game, even down to the more common zombies. This prompts a more evasive and cunning playstyle instead.
  • Puzzles are harder to figure and require slightly more backtracking compared to easier modes.
  • Some event checklist are exclusive to Very Hard mode, thus players are required to play the mode through to achieve 100% checklist.
  • A supplementary option dubbed "Nightmare" can be unlocked in File#2 which further increases enemy aggression and damage; rendering most zombies as hyper zombies, whilst increasing the enemies' overall damage output.

Outbreak series feature starkly different experience in this mode. A prime example being during the level Outbreak, in which Bob becomes a zombie and will attack Mark instead of committing suicide as in easier modes.

On the mainline entries, the mode often forced players to be quick on their feet and adapt to a more aggressive composition of enemies ergo their AI behavior.

Oftentimes, the mode punishes players to near-death state with a single hit for any form of mistake.

Nightmare can be purchased in the Store for 10000 Points after Finishing each Scenario in the game on the Very Hard difficulty. In this mode, the only thing that changes in the gameplay is that healing items heal only 75% of their usual percentage and enemies can inflict 30% more damage to the player character. As an interesting addition, it can be used with any level of difficulty, which keeps the same location for items and enemies in their specific difficulty without changing. For very experienced players, one should try to combine Nightmare mode with Very Hard difficulty and achieve a No Damage Taken bonus; This rewards players with more than 10000 points for the collection.

Difficulty affects

  • Damage taken
  • Damage dealt


  • QTEs will be performed automatically (explained by the game).



  • Characters can bump into walls from this difficulty and above, and they lose a small amount of combat gauge.


  • Enemies deal high damage, taking at least 2 health blocks from a clean hit and possibly more if players fail any proceeding QTE grab prompts. It's not uncommon for players to fall into Dying state if they fail said QTE.
  • Enemy AIs are far more persistent
  • They also get up quickly after being knocked down.

  • Skill Points that appear are worth double.

Revelations 2

Resident Evil 7: Biohazard

In the main game, Madhouse changes the game in a far more different approach compared to the previous difficulties, making the gameplay much more intense:

  • Enemies are far more stronger and formidable, using their stronger attacks much often.
    • Aside from the aforementioned stronger enemies, the player will now encounter more of them.
    • Some scripted events where enemies will spawn after obtaining Key Items or unlocking new areas are slightly changed.
    • Enemies that will be encountered later on in the game such as Quick Molded are now encountered much earlier.
  • Saving in Video Recorders now requires Cassette Tape to save data.
  • More Antique Coins are scattered around the game's locations, with some being in objects that the player can examine.
    • Specific Key Items will now require Antique Coins to be unlocked, as opposed to tracking them in rooms.
    • The Main Hall now has bird cages, with some being Power Up Coins to bolster the player's stats.
  • Items in the game are harder to find such as weapon ammunition or resources.
    • Separating Agent is much more frequent in this mode, forcing the player to sacrifice their resources wisely for the sake of crafting another resource.
  • Less frequent auto saves.

Professional (Not A Hero) and Joe Must Die (End of Zoe) difficulties are only exclusive to the respective DLCs of the game. Both difficulties behave similarly to Madhouse mode.

Professional mode forces the player to start with a Tactical Knife while their other main weaponries can be retrieved in selected locations.

Joe Must Die mode features a unique item called the Throwing Knife where its sole purpose is to simply lure enemies or set up traps due to explosive canisters and Tripwires being frequent in this mode.
