This guide details the multi-step process for unlocking the secret prototype weapon in Battlefield 2042, a unique firearm featuring a thermal sight, fully automatic, and air burst modes. The unlocking sequence, discoverable solo, involves three main phases across different Portal server maps: first, obtaining a hidden key card on "Battle of the Bulge (Night)"; second, unlocking and equipping a specific Phantom specialist skin by performing self-healing rituals at multiple flags on "Exposure"; and finally, inputting four complex code sets into a keypad on "Hourglass" to gain access to a secret facility. The final stage requires navigating traps (including a deadly elevator sequence requiring a prone stance if solo, and laser grids requiring the Phantom skin) to retrieve the weapon and an additional skin from a hidden chamber. The video also touches on potential multiplayer requirements for some steps and various Easter eggs related to the Battlefield lore.
Summarizing the Prototype Weapon Unlock in Battlefield 2042
0:00 Unlock the Prototype Weapon: This video details how to unlock a secret prototype weapon in Battlefield 2042, which features a thermal sight, full auto, and air burst firing modes. This can be done solo.
1:48 Set up a New Portal Server: Create another Portal server on the "Exposure" map (use provided code AA1X8Q).
1:58 Choose Falck & Equipment: Select Falck as your specialist and equip the crossbow with explosive bolts or mini grenades.
2:09 Self-Heal at A1 Objective: Run (do not use vehicles) to the A1 objective. Stand near the flag, injure yourself with the crossbow/grenade, then shoot Falck's S21 Syrette Pistol at the ground and pick up the syrette to heal. Repeat this process 10 times, staying close to the flag and ensuring you don't die.
3:12 Self-Heal at B1 Objective: Jump off the cliff (pop parachute, do not die) and head to the B1 objective (inside the tunnel). Repeat the 10 self-heal cycles near the flag.
3:48 Self-Heal at B2 Objective: Head up the stairs to the B2 flag. Repeat the 10 self-heal cycles near the flag.
4:07 Self-Heal at D1 Objective: Break a window, jump off (parachute, do not die) to the D1 flag. Repeat the 10 self-heal cycles near the flag.
4:39 Self-Heal at C1 Objective: Go on foot to the C1 flag. Repeat the 10 self-heal cycles near the flag.
5:09 Call in a Vehicle: While remaining on the C1 objective, open your calling tablet and call in an LATV4 Recon vehicle directly onto the flag.
5:41 Unlock Skin: Get into the called-in vehicle. This action will unlock the support specialist set of Phantom skins.
5:51 Equip Phantom Skin: Disconnect from the game, go to "Classes" in the main menu, and equip one of the newly unlocked Phantom skins (e.g., "Pharmacon" for Falck).
6:09 Set up a Portal Server on Hourglass: Create a Portal server on "Hourglass Conquest" (use provided code AA1X9Y) and set a password.
6:22 Choose Specialist & Skin: Play as your support specialist (e.g., Falck) with the Phantom skin equipped.
6:34 Locate the Keypad: Spawn in a Pawn Hawk vehicle and head to the area below the C1 objective, where you'll find a giant drill and a keypad.
6:56 Keypad Interaction: Use the keypad's "Up," "Down," "Clear," and "Submit" options to input digits. The goal is to turn four lights green by entering four code sets.
8:58 Navigate to the Facility Entrance: Use your vehicle (or run) towards the A objectives, through a tunnel, past a boring machine, and into a red tunnel.
9:25 Open the "STOP" Door: At the end of the red tunnel, find and open a door marked "STOP" (this requires successful keypad input).
9:41 Call the Elevator: Inside, call the elevator.
9:59 Go Prone in Elevator (Crucial for Solo): As soon as you interact with the panel to send the elevator down, immediately go prone to avoid instant death if playing solo.
10:20 Access Laser Room: Exit the elevator and interact with a keypad (enabled by the key card) to open doors to a room with lasers.
10:39 Pass Through Lasers: Navigate through the laser room. You must be wearing the Phantom skin to survive the lasers.
10:48 Locate the Weapon: At the end of the laser room, open another set of doors into a warehouse. The prototype weapon will be visible in a display case.
10:59 Unlock the Weapon: Shoot the glass and pick up the prototype weapon to unlock it.
11:07 Get a Weapon Skin: Look up in the same room and hold interact to acquire a skin for the weapon ("Prototype Wrap").
11:43 Conclusion & Additional Info: The prototype gun is now unlocked. The process might still have some bugs. A multiplayer method involving four players (with different Phantom tags) in the elevator is mentioned as the likely intended design, which bypasses the need to go prone. Once the key card is obtained, the initial facility door can be reopened without repeating the Battle of the Bulge steps.
