====== Challenges ======

In addition to varying the [[:modes:|game difficulty setting]], some players take on **challenges** to complete the game under artificial restrictions. Players typically attempt challenges in order to raise the difficulty level, test their skills, add variety to their play, and push the limits of what is possible in the game.

In addition to the challenges listed on this page, higher game difficulty settings such as [[Expert Plus]], [[Expert Plus Plus|Expert++]], [[Iron Man]] and [[Time Attack]] modes can also be considered as challenges. The challenges listed here can be attempted at different game difficulty settings, and can be combined with other challenges, such as [[#No Items]]/[[#Far Travel]].

===== Agent Alone =====

The **Agent Alone** challenge is to beat the game with just one [[:agent]], not counting agents who join the team for [[:missions:#special missions]].

  * You may start with any two agents, but the second starting agent must not leave the starting room in the first mission, and must be "lost in the field".
  * You may take and keep [[:items:]] (including [[:weapons:]]) from the second starting agent, and use them to [[:strategy:distraction|distract]] guards in the first mission, as long as they stay in the starting room.
  * You must not add an agent to your team by rescuing them from a [[:missions:Detention Center]]. You may release an agent from their cell and use the agent to assist in that mission, but if so, they must be "lost in the field" in that mission.

The Agent Alone challenge was [[https://forums.kleientertainment.com/forums/topic/56376-agent-alone-challenge-playstyle-proven-as-well/|first proposed]] on the official Invisible, Inc. forum by Celestael. The challenge can be simplified by playing with the [[:mods:Lone Start]] mod, which allows you to start the game with just one agent; this adds to the difficulty since you cannot take items from the second agent, or use them to distract guards in the first mission.

===== Pacifist =====

The **Pacifist** challenge is to beat the game without harming any [[:guards:]] or destroying any [[:mainframe devices:]].

  * You must not [[:KO|knock out]] or [[:lethal damage|kill]] any guard, including [[:civilians]].
  * You must not destroy [[:drones]], [[:mainframe devices:Security Cameras]] or [[:mainframe devices:Turrets]].
  * You may carry and sell [[:weapons:]] which deal damage, as long as you don't use them.
  * Using a [[:weapons:TAG Pistol]] is allowed, as it does not deal damage.

===== No Items =====

The **No Items** challenge, or **No Inventory** challenge, is to beat the game without using any [[:items:]] (including [[:weapons:]]).

  * You must not use any [[:items:]], including [[:weapons:]] and [[:items:#special items]] such as [[:items:Lvl1 Security Passcards]] or [[:items:Vault Access Cards]].
  * You may carry and sell items, as long as you do not use them. You are allowed to receive rewards for carrying items such as a [[:items:Site List]] or [[:items:Valuable Tech]] out of a mission.
  * You may install [[:augments:]], as these are not used from the agent's inventory.

No Items is almost but not quite a stricter challenge than [[#Pacifist]], since in the No Items challenge you are still permitted to harm guards using hacked [[:drones]], [[:mainframe devices:Turrets]] or lethal [[:mainframe devices:Laser Panels]].

===== Far Travel =====

The **Far Travel** challenge is to beat the game while only infiltrating [[:missions:]] which have the greatest travel time on the [[:world map]]. If there is more than one mission option with the same greatest travel time, you may choose which to infiltrate.

===== No Incognita =====

The **No Incognita** challenge is to beat the game without using any [[:programs:]].

  * You must not use any active programs, and you must not start with or install any programs with passive effects.
  * You may sell programs at [[:mainframe devices:Server Terminals]].
  * You may acquire new programs (e.g. from [[:missions:Program Compile]] side-missions), as long as you do not use them, and as long as they have no passive effects.
  * You may use [[:Incognita#Incognita view]] to activate or deactivate devices or items such as [[:mainframe devices:Power Supply|Power Supplies]], [[:mainframe devices:Turrets]] or the [[:items:Transport Beacon]].

===== Snail Legs =====

The **Snail Legs** challenge is to beat the game starting with [[:agents:Dr. Xu]] and [[:agents:Archive Sharp]], and without upgrading their [[:skill#Speed]] skill level. (This also means not installing the [[:augments:Kinesiology Brain Chip]] augment.) The challenge is named because these two agents have 1\ [[:AP]] less than other agents.

As an optional additional rule, you must also not use any [[:items:]], [[:augments:]] or [[:programs:]] which give extra AP.

===== Always Sprint =====

The **Always Sprint** challenge is to beat the game while only [[:sprinting]].

  * [[:Agents:]] (and rescued [[:Prisoners]]) may only move while the "sprint" ability is enabled.
  * [[:Peeking]] and [[:observing]] guards' movements is allowed while not sprinting.
  * If an agent (or Prisoner) does not have enough [[:AP]] to enable sprinting (e.g. due to [[:peeking]] or [[:observing]], or being [[:encumbered]]), then they must not move on that turn unless they gain enough AP to enable sprinting first.
  * Hacked [[:drones]] and rescued [[:Couriers]], which do not have the "sprint" ability, may move normally.

===== No Peeking =====

The **No Peeking** challenge is to beat the game without [[:peeking]], [[:observing]] guards' movements, or [[:TAG|TAGging]] guards.

===== Maximum Daemons =====

The **Maximum Daemons** challenge is to beat the game with various restrictions relating to [[:daemons:]]:

  * The "daemon quantity" must be set to "more" as a [[Custom]] setting.
  * You must start the game with [[:programs:Ritual]] as your breaker program.
  * You must only use daemon-related programs; you must not use any other programs, with the exception of your starting [[:programs:generator]].
  * Whenever you have the opportunity to install a daemon-related program, you must do so, even if you have to sell a non-daemon-related program (other than your starting generator) to do so.
  * You must not sell daemon-related programs.
  * You may install non-daemon-related programs in order to sell them, as long as you do not use them, and as long as they do not have passive effects.
  * As an optional additional rule, you must start the game with [[:programs:Faust]] as your generator program.
  * As an optional additional rule, you must start the game with [[:agents:Central]] and [[:agents:Monst3r]] on your team.

The daemon-related programs are [[:programs:Bless]], [[:programs:Brimstone]], [[:programs:Daemon Sniffer]], [[:programs:Faust]], [[:programs:Fool]], [[:programs:Hunter]], [[:programs:Ritual]] and [[:programs:Taurus]]. It is recommended to play with the [[:mods:Scrolling Daemons]] mod as there will be many daemons active at the same time, and the [[:mods:Programs Extended]] mod which adds several new daemons and daemon-related programs. If playing with the [[:mods:New Items and Augments]] mod, it is recommended to disable "Starting Agents Rebalance" for the vanilla [[:augments:Antiviral Proxy]] effect.

The Maximum Daemons challenge was proposed by [[twitch>wodzu_93]] and [[twitch>Anistuffs]]. Because the challenge requires starting with [[:programs:Ritual]], it can only be attempted on the [[:Nintendo Switch edition]] of the game, or when playing with the [[:mods:Switch Content]] mod.

===== No Hacking Cameras =====

The **No Hacking Cameras** challenge is to beat the game without hacking any [[:mainframe devices:Security Cameras]]. It is forbidden to fully break the firewalls on a camera, using [[:Incognita]] or otherwise. Hacking [[:guards:Camera Drones]] is permitted, as is rebooting cameras using [[:EMP]] effects (including [[:programs:Fool]]).

As an optional additional rule, you must not [[:cloaking|cloak]] or use [[:agents:Archive Prism]]'s [[:items:Holo Projection Mesh|disguise]].
