Each entry includes function, acquisition, optimal use, and any upgrades or synergies.

Weapons & Tools

1. Revolver

• Function: Low-damage firearm; useful for breaking locks, stunning humans, or creating noise to distract the Alien. Ammo is very limited.


• Obtain: Found in Mission 3 (San Cristobal Medical Facility) on a desk in the treatment room.


• When Useful: Early game against hostile humans; rarely effective against the Alien. Best used as a noise maker.


• Upgrades: None. Ammo can be crafted from scrap (see Crafting).




2. Shotgun



• Function: Powerful close-range weapon; can stun the Alien for a few seconds, allowing escape. Fires shells, which are rare.


• Obtain: In Mission 6 (Solanos / Lorenz Systech Spire) – located in a locked safe (code 3861) or later in the transit hub.


• When Useful: Last resort against the Alien; one direct shot can force it to retreat. Also effective against humans and Working Joes.


• Upgrades: None. Shells can be crafted from scrap and gunpowder.




3. Flamethrower



• Function: The most effective weapon against the Alien. Fuel blasts cause the Alien to flee and hide in vents, buying you precious time. Can also ignite flares.


• Obtain: Mission 10 (Syndicate / Pioneer) – in the room before the elevator to the reactor.


• When Useful: Primary defense against the Alien after Mission 10. Use short bursts to conserve fuel; longer bursts cause it to retreat further. Also damages Working Joes.


• Upgrades: None. Fuel can be crafted from chemicals and scrap.




4. EMP Mine



• Function: Disables electronic devices (door panels, cameras, Working Joes) in a radius. Can be placed or thrown. Emits a loud noise that can attract the Alien.


• Obtain: Blueprint found in Mission 5 (Sevastopol Station – Engineering). Craft from electronics and metal parts.


• When Useful: Dealing with multiple Working Joes or disabling security cameras. The noise can be used to lure the Alien away from a path. Works on the Alien? No – it is biological.


• Synergy: Combine with a noise distraction to herd enemies.




5. Pipe Bomb



• Function: Lethal explosive; can kill humans instantly and severely damage the Alien (forces retreat). Loud, attracts enemies.


• Obtain: Blueprint in Mission 5 (Engineering). Craft from explosive powder, metal parts, and chemical components.


• When Useful: Clearing a room of humans or as a last resort against the Alien. Use with caution because of noise.


• Note: The Alien can be killed by a direct hit? No, but it will flee for an extended period.




6. Flashbang (Noise Maker)



• Function: Creates a bright flash and loud bang. Stuns humans and Working Joes briefly; attracts the Alien to the location.


• Obtain: Blueprint in Mission 2 (Backup Power Relay). Craft from scrap and electrical components.


• When Useful: Distracting enemies, blinding humans to slip past, or redirecting the Alien. Essential for stealth.


• Synergy: Use while hiding in a locker; the Alien will investigate the noise and leave.




7. Smoke Bomb



• Function: Creates a cloud of smoke that obscures vision for humans and the Alien. Does not block the Alien's hearing or sense of smell.


• Obtain: Blueprint in Mission 8 (Team Briefing / Cargo Bay). Craft from chemicals and metal parts.


• When Useful: Crossing open areas under surveillance, escaping combat, or blocking line-of-sight for security cameras.




8. Flashlight



• Function: Illuminates dark areas. Attracts the Attention Meter (not the Alien directly) – enemies can see light.


• Obtain: Equipped from start. Can be toggled on/off.


• When Useful: Essential for navigation but risky. Use sparingly; use the motion tracker to navigate without light.


• Upgrades: None; however, you can find a Flashlight Upgrade in Mission 8 (Projector Room) that increases brightness but also draw more attention – use with discretion.




9. Motion Tracker



• Function: Detects moving enemies (humans, Working Joes, and the Alien) within a 30-meter range. Shows distance via blips. Does not detect stationary enemies or unconscious bodies.


• Obtain: Equipped from start.


• When Useful: Vital for situational awareness – always keep on. The Alien can hear the tracker's beeping if you are close; use it in short bursts.


• Upgrades: None.




10. Maintenance Jack



• Function: Melee tool; used to break vents, open stubborn doors, and as a weapon (weak).


• Obtain: In Mission 1 (Start of game).


• When Useful: Opening shortcuts, breaking vents to create hiding spots, and as a last-resort melee attack against humans.


• Note: The Jack can be used on certain panels to disable alarms temporarily.




11. Hacking Device



• Function: Used to hack datapads and security terminals to unlock doors, turn off cameras, etc. Requires a minigame; higher-level locks need more time or skill.


• Obtain: In Mission 3 (Medical – after meeting Samuels).


• When Useful: Accessing locked rooms, disabling door security, or reading logs. Some terminals can deactivate reactor alarms.


• Upgrades: None; but you can find Hacking Mods (e.g., “Agility” reduces noise during hack) in some lockers.

3. Keycards & Passcodes



• Function as keys to unlock doors. Not a currency but essential for progression.

Special Items & Synergies





The Alien’s Behavior Modifiers



• Flares+Flames: Fire deters the Alien for ~10 seconds. Use before sprinting through an area.


• Noise Makers + Locker: Effective combo to dispatch the Alien to a different room.


• EMP + Working Joes: Disable multiple androids silently, but the EMP attracts the Alien.


• Flashlight + Smoke Bomb: Flashlight through smoke can blind you, but enemies can still see your light – not recommended.




Best Practices for Item Use



• Always carry a stack of Noise Makers and Smoke Bombs. They are cheap to craft.


• Save Flamethrower fuel for critical moments. Each full tank (200 units) can make the Alien flee about 4-6 times.


• Collect Medkit blueprint early; scrap is abundant but chemicals are rarer.


• Upgrade Flamethrower fuel efficiency ASAP.

Item Rarity & Availability by Difficulty




• Novice: Abundant ammo and medkits. Crafting materials spawn more frequently.


• Hard / Nightmare: Drastically reduced resource spawns. The Alien is more persistent. Crafting becomes essential.


• General Rule: Resources do not respawn; once taken, they are gone. Plan your crafting carefully.
