IPSF Base Door Code
Door Code: 2765
The IPSF Base door code is obtained during the main mission, Behind Seven Seals, if you gave the Ward sensors to Richter during A Needle in a Haystack. After exploring the Abandoned Communications Hub near Zalissya (Ribs POI), you'll get the code 2765 needed to open the IPSF Base Door.
Opening this door allows you to access the Sphere without having to resort to a frontal assault or a stealth sequence when entering from aboveground. This is particularly useful if you're looking to catch Solder unawares during Behind Seven Seals.
How to Reach the Sphere Code Door in the IPSF Base
| 1 |  From Zalissya, head southwest until you reach the swamp to the north of the Sphere. |
|---|---|
| 2 |  From there, head into the swamp and go towards the direction of the Sphere. You should see the access tunnel in the distance. |
| 3 |  Go to the end of the access tunnel filled with acid anomalies. |
| 4 |  At the end of the tunnel, you'll find the code locked door leading into the IPSF Base. Use the code, 2765 to open it. |
IPSF Base Door Location
Found in an Access Tunnel at the Swamp Near the Sphere
The IPSF Base Door will be found at the end of an underground access tunnel whose entrance is located in the swamp next to the Sphere. From Zalissya, head southeast to reach the swamp and the access tunnel leading into the bowels of the Sphere.
