  Human
• None (Physical AI Combat Companions): Alyx undertakes her physical journey through City 17 alone. She does not have any AI-controlled combat companions that follow her or fight alongside her in the traditional sense, emphasizing her vulnerability and resourcefulness in the VR environment.

• None (Gameplay - Colt's Perspective): Colt Vahn operates as a lone assassin throughout his attempts to break the loop. He does not have any AI companions that follow him or assist in combat during his playthrough.
• Julianna Blake (Via Radio Comms & Invasions): While primarily an antagonist, Julianna is a constant presence via radio, engaging in witty, taunting, and sometimes informative banter with Colt. When she invades (as AI or another player), she acts as a direct, intelligent adversary, but not a companion.
  Human (Visionary)
• Themselves (Multiple Wenjies): Dr. Wenjie Evans has multiple versions of herself existing simultaneously in her lab due to time loop experiments. While these are all 'Wenjie' and act as enemies, they can sometimes interact with each other or be manipulated by Colt, creating a unique dynamic unlike traditional companions.
  Human (Visionary Clones)

• Resin: Small, orange, cylindrical pieces of Combine material found scattered throughout all levels, often in crates, shelves, or hidden nooks. Collected and used at Combine Fabricator stations to upgrade Alyx's three main weapons (Pistol, Shotgun, SMG).
• Ammo (Pistol Clips, Shotgun Shells, SMG Power Cells): Found in Combine supply crates, on defeated enemies, or in the environment. Essential for combat. Alyx can store a limited amount on her person and in her backpack.
• Health Syringes: Medical items that restore Alyx's health. Found in medical kits, bathrooms, or sometimes dropped by Combine medics. Stored in wrist slots for quick access.
• Combine Grenades: Standard fragmentation grenades used by the Combine. Can be found in the environment or taken from defeated enemies. Stored in wrist slots.
• Grub Nests / Antlion Grubs (Healing Items - Minor): In Xen-infested areas, Alyx can find Antlion grubs in nests. Crushing them provides a small amount of healing. A nod to Half-Life 2: Episode Two.
• Vodka Bottles (For Jeff sequence): Specific to Chapter 7: Jeff. Vodka bottles are used as throwable distractions to lure the sound-sensitive creature Jeff away from Alyx's path.
• Battery Cells (For Multi-Tool Puzzles): Small cylindrical batteries that must be found and inserted into specific slots to power up doors, lifts, or other machinery as part of environmental puzzles solved with the Multi-Tool.
• Hidden Gnome Chompski (Easter Egg): A single, well-hidden garden gnome. Finding it and carrying it to a specific later point in the game unlocks an achievement, referencing a long-running Valve gag.

• Slabs & Slab Upgrades: Slabs (supernatural powers) are initially acquired by assassinating the Visionary who possesses them. Slab Upgrades are earned by defeating that Visionary again in subsequent loops, or by defeating an invading Julianna who is using that Slab. These upgrades enhance the functionality of each Slab (e.g., Shift can be upgraded to allow hovering or reaching further).
• Trinkets (Character & Weapon): Found throughout Blackreef in containers, on Eternalists, or as rewards for completing small objectives or puzzles. Character Trinkets provide passive buffs to Colt (e.g., increased health, double jump, faster movement). Weapon Trinkets enhance firearms (e.g., faster reload, increased accuracy, silenced shots, elemental bullets).
• Residuum: A shimmering energy resource collected from glowing objects, downed Visionaries, or by sacrificing unwanted Infused gear. Used at the end of each time period (Morning, Noon, Afternoon, Evening) to 'Infuse' weapons, Slabs, and Trinkets, allowing them to be carried over to the next loop. Essential for permanent progression.
• Documents (Notes, Letters, Schematics, Audiologs): Readable or listenable lore items found throughout all districts. They provide crucial backstory on the AEON Program, the Visionaries, Colt's past, Julianna's motivations, the nature of the time loop, and clues for assassinating targets or solving puzzles. Key to unraveling Blackreef's mystery.
• Weapon & Gear Tiers (Common, Rare, Epic - Indicated by color): Weapons and some Trinkets can be found in different rarity tiers, with higher tiers often having more perk slots or better base stats. Colt will typically seek out higher-tier versions of his preferred gear.
• Leads & Discoveries (Visionary Leads, Arsenal Leads): Information gathered by Colt that is tracked in his menu. Visionary Leads provide clues about targets' schedules, weaknesses, and how to manipulate events to line them up for assassination. Arsenal Leads point towards unique weapons or powerful Slabs/Trinkets.

• Slab Abilities (Defensive Uses): Certain Slabs, like Havoc (which absorbs damage and unleashes it), Aether (invisibility for evasion), or Shift (for quick escapes), provide significant defensive capabilities when used effectively.
• Reprise Ability: Colt has a built-in 'Reprise' ability that allows him to die twice within a single district/time period before the loop fully resets for that district attempt. This acts as a form of extra lives or resilience.

• Alyx Vance's Standard Attire: Alyx wears a consistent outfit throughout the game, consisting of a practical jacket (often with a Black Mesa logo reference), shirt, pants, and her iconic fingerless gloves which house her health/ammo display and are part of the Gravity Glove system. There are no player-controlled clothing customization options for Alyx; her appearance is fixed for the narrative.
• Gravity Gloves ('Russells'): These are a key piece of Alyx's gear, not clothing in the traditional sense, but visually distinct. They are black and yellow and integral to her ability to interact with the VR world. They are not customizable in appearance.

• Colt Vahn's Attire (Default & Unlockable Skins): Colt has a signature default outfit (leather jacket, turtleneck). Players can unlock additional cosmetic skins for Colt through game progression, special editions (e.g., 'Party Crasher' skin), or updates. These change his appearance but offer no gameplay advantages.
• Julianna Blake's Attire (Default & Unlockable Skins): Julianna also has a default outfit and can unlock additional cosmetic skins for when she is player-controlled in the 'Protect the Loop' mode (e.g., 'Sharp Shooter' skin).
• Weapon Skins (Limited): Some unique or Deluxe Edition weapons come with specific skins. A broader weapon skin customization system is not a primary feature, though Trinkets can sometimes alter weapon appearance slightly or add visual effects.

• None (Player Controlled for General Traversal)
  Alyx Vance traverses all environments on foot using various VR locomotion options (Teleport, Shift, Continuous). There are no player-controlled vehicles like cars, bikes, or aircraft for general navigation in the game.
• Combine Razor Train (Contextual / Environmental): Mass Transit / Enemy Transport
  The iconic Combine Razor Trains are present in City 17's environment and feature in some scripted sequences or as background elements, but Alyx does not pilot or directly control them.
• Lifts & Elevators (Environmental): Mechanical Traversal
  Various lifts and elevators are found within levels, providing vertical traversal. Alyx interacts with them to move between floors or different sections of a facility.

• No Player-Controlled Vehicles (General Traversal)
  Colt Vahn primarily traverses the districts of Blackreef on foot, utilizing his parkour-like agility and supernatural Slab abilities (like Shift for teleportation). There are no player-drivable cars, bikes, or other traditional vehicles for general exploration within the districts.
• Tunnels / Access Points (Between Districts & Time Periods): Map Transition Mechanic
  Colt travels between the four main districts (Updaam, Karl's Bay, Fristad Rock, The Complex) and advances the time of day (Morning, Noon, Afternoon, Evening) by returning to his underground tunnels/bunker and selecting his next destination and time slot from a map interface. This transition involves a loading screen and is how the 'loop' progresses from one segment to the next.
• Contextual Traversal Aids (e.g., Ramps for Sliding, Cranes, Rooftops): Environmental Elements
  Levels are designed with verticality and interconnectedness, featuring environmental elements like ramps for sliding, rooftops for parkour, cranes, or other structures that Colt can interact with or use to his advantage for traversal and stealthy approaches.

• Q: What is the main objective in DEATHLOOP?
  A: The main objective is to break the time loop by assassinating all eight Visionaries on Blackreef island within a single day. This requires investigating their routines, finding ways to get them in the same place or eliminate them efficiently across four time periods (Morning, Noon, Afternoon, Evening) in four different districts.
• Q: How does the time loop mechanic work?
  A: The day on Blackreef resets at the end of the Evening, or if Colt dies three times within a single district visit (his 'Reprise' ability allows two revivals). When the loop resets, non-Infused weapons, Slabs, and Trinkets are lost, and Visionaries/Eternalists respawn. However, Colt retains all learned information (Leads) and any gear he has 'Infused' with Residuum.
• Q: What is Infusion and Residuum?
  A: Residuum is a resource Colt collects from glowing objects or by sacrificing gear. Between time periods (e.g., when returning to his bunker), Colt can spend Residuum to 'Infuse' weapons, Slabs, and Trinkets he wants to keep. Infused items will carry over to subsequent loops, allowing for permanent progression of his loadout.
• Q: Can another player really hunt you as Julianna?
  A: Yes, DEATHLOOP features an optional online multiplayer mode called 'Protect the Loop.' If enabled, another player can invade your game as Julianna Blake, with the objective of killing Colt. You can also set this to 'Friends Only' or 'Offline' (where an AI Julianna will invade).
• Q: Are Slabs like Dishonored's powers?
  A: Yes, Slabs are very similar to the supernatural powers found in Arkane's Dishonored series. They grant unique abilities like teleportation (Shift), invisibility (Aether), telekinesis (Karnesis), linking enemies (Nexus), and a combat buff (Havoc). They are acquired from Visionaries and can be upgraded.
• Q: Is DEATHLOOP connected to the Dishonored universe?
  A: While not officially confirmed as a direct sequel or prequel, there are numerous fan theories and subtle hints within DEATHLOOP (and Dishonored: Death of the Outsider) that suggest a possible connection or shared multiverse between the two Arkane franchises. However, DEATHLOOP can be fully enjoyed as a standalone story.

Developed on the Source 2 Engine, Half-Life: Alyx sets a new benchmark for visual fidelity and detail in VR. It features incredibly realistic environments with high-resolution textures, advanced lighting and shadow effects, and detailed character/enemy models.

• Key Settings Impact: In-game graphics fidelity settings (Low, Medium, High, Ultra), the VR headset's native refresh rate (e.g., 90Hz, 120Hz, 144Hz), and the render resolution (per-eye) are the most significant factors affecting performance and visual quality. Maintaining a stable framerate matching the headset's refresh rate is crucial for a comfortable and immersive VR experience.

• Upscaling Tech: Supports AMD FSR 1.0 & 2.0. NVIDIA DLSS support is not native but might be achievable via mods or driver-level settings for some users.
• Key Settings Impact: Texture Quality, Shadow Quality, Model Detail, Ambient Occlusion (HBAO+), View Distance, Anti-Aliasing, and Post-Processing effects heavily impact performance.

• G P U T G P: Adequate TGP is crucial for VR performance on laptops, ensuring the GPU can deliver its expected power.
• Cooling Thermals: Excellent cooling is essential to prevent thermal throttling and maintain stable frame rates, which is vital for VR comfort.
