In most games in the Call of Duty series there are four difficulty levels in the campaigns (four more introduced in Call of Duty: Black Ops III, Call of Duty: Infinite Warfare, and Call of Duty: Modern Warfare). Each is different, with Recruit being the easiest and #YOLO being the hardest.
Recruit[]
- "For players new to first person action games"
- — In-game description
- Main article: Recruit
Recruit is one of the five difficulty settings in the Call of Duty series. It is the easiest of the five difficulties, as the player takes small amounts of damage from most weapons and the AI is generally inaccurate. This difficulty is recommended for players new to the First Person Shooter genre.
Over the course of the series, this difficulty mode has had different names. In Call of Duty and Call of Duty: United Offensive, it is called "Greenhorn" and in Call of Duty: Finest Hour, Call of Duty 2: Big Red One, Call of Duty 2 and Call of Duty 3 it is called "Easy".
Regular[]
- "Your abilities in combat will be tested."
- — In-game description
- Main article: Regular
Regular is one of the difficulties in the Call of Duty series. It can generally be considered the "normal" difficulty setting as it is slightly harder than Recruit, but easier than Hardened and Veteran.
Hardened[]
- "Your skills will be strained."
- — In-game description
- Main article: Hardened (difficulty)
Hardened is one of the difficulty settings in the Call of Duty series. It is harder than Recruit and Regular but easier than Veteran. Playing on Hardened mode allows players to achieve many of the trophies and achievements that can only be obtained by playing on the harder difficulties, without actually playing on Veteran.
Veteran[]
- "You will not survive."
- — In-game description
- Main article: Veteran (difficulty)
Veteran is one of the most challenging difficulty that are in the Call of Duty series. The player will find they will take much more damage and have very low health, with enemies having increased accuracy and deadly reaction time.
Realistic[]
- "Brutally difficult and entirely unforgiving."
- — In-game description
- Main article: Realistic
Realistic is a difficulty featured in Call of Duty: Black Ops III, and the hardest difficulty of the game. In Realistic, the player will only have a very little amount of health, will die by one shot or explosion and a limited HUD.
The AI is said to be independent in this level and is generally more aggressive and smarter than on Veteran.
Specialist[]
- "Manage your health and inventory in order to survive. Only Elite Specialist accept this challenge."
- — In-game description
- Main article: Specialist (Difficulty)
Specialist is a difficulty featured in Call of Duty: Infinite Warfare, this is the second hardest difficulty in the game. In Specialist the player only has a little health. Health can only be regenerated by nano shots, helmets will need to be replaced. Getting shot in any part of the body affects your movement and shooting.
#YOLO[]
- "No checkpoints, no room for error, no mercy."
- — In-game description
- Main article: YOLO
#YOLO is a difficulty featured in Call of Duty: Infinite Warfare, and is the hardest difficulty of the game. The #YOLO difficulty is very similar to Specialist difficulty, having roughly the same mechanics in terms of damage and weapons. The key difference however, is that if the player dies, they will have to start the entire Campaign over.
Realism[]
- Main article: Realism (difficulty)
Realism is a difficulty featured in Call of Duty: Modern Warfare, Call of Duty: Black Ops Cold War and Call of Duty: Modern Warfare II. Realism works in similar fashion as the Veteran difficulty but with a limited HUD.
Difficulty In Other Modes[]
Black Ops Zombies[]
The mobile version of Call of Duty: Black Ops features Easy, Normal, and Hard difficulties, each affecting the aggressiveness of Zombies; on Easy, Zombies won't appear to sprint until later rounds, and on Hard, Zombies will begin to sprint at much earlier rounds.
Black Ops II Zombies[]
- "Feeling tired or rundown? Try reducing the difficulty."
- — In-game description
Call of Duty: Black Ops II features two separate difficulties for Zombies, those being "Easy" and "Original." On Easy, fewer Zombies will appear to sprint at full speed (with the exception of Zombies chasing after the bus on TranZit and the Tank on Origins). Easter Eggs cannot be completed while playing on Easy. Easy difficulty can only be played on Local, system link/LAN, and Custom Games.
Extinction[]
Casual: The number of Cryptids that appear are reduced by 50%, their health is also reduced by 50%. Cryptids are not as aggressive as before the patch, players will take less damage as a result. Players also spend less money by having to use their abilities less often (the prices are still the same and it's the frequency of using them to resupply/re-armor that allows players a full bank most of the time in this difficulty). Playing on Casual, however, does not count towards leaderboard placings; scores won't be posted, escapes will not count. But, the number of Cryptids the players kill will still count towards the 10,000-weapon-kill operation and still earn the Multiplayer patch. Additionally, escaping while using a Relic will also still count towards the background challenges. A recent update made a casual playlist online, with rotating maps.
Regular: This difficulty is essentially the way the mode has been played before the patch.
Hardcore: The crosshairs on the player's HUD is removed, the Cryptids are more aggressive and skill points are not earned for destroying hives. Ricochet friendly fire is also turned on. Substantially more difficult enemies appear to spawn much earlier on. Players tend to be faced with Hunters on the very first hive. Specifically on Point of Contact, within the first area, players come face to face with large numbers of Meteors/Seekers. A recent update made on online hardcore playlist, with alternating maps.
Black Ops 4 Zombies[]
In Call of Duty: Black Ops 4, four difficulty levels are available in the Zombies mode. The Casual difficulty lets players start with 250 Health points, allowing them to be hit up to 4 times before being downed. This difficulty also features less agressive and slower enemies, however most quests and easter eggs are disabled. The Normal diffculty features 200 Health points, allowing the players to be hit up to 3 times. The Hardcore difficulty features 150 Health points, allowing the players to be hit up to 2 times. The Realistic difficulty only features 50 Health points, as such the players can be downed with a single hit from an enemy.
