SCP-902 | The Final Countdown

by TheCaptainFoxy

SCP-902 | The Final Countdown adds a ticking bullet box from the SCP Foundation setting, found only in a containment chamber and built for Forge 1.20.1.

ForgeClient and serverAll rights reserved1.20.1

What it does

The box is found only inside an SCP-902 Containment Chamber or Cell, which spawns rarely in snowy and frozen biomes at surface level, roughly one structure per 4,000 blocks. A player can locate it with the locate command. Right-clicking reads the document that comes with it, and shift with a right-click places the box in the world.

Once a player has read the document, the mod starts a countdown that ticks at intervals of up to 5 minutes. Once a placed box is opened, its contents and the list of items that must be destroyed appear, and smashing the box before the timer runs out causes the camera to jerk while on-screen text speaks the player's own thinking. Keeping the item in the inventory also causes ticking and paranoia. The mod is built on GeckoLib, which is required for the SCP-902 model animations.

Installation needs GeckoLib for Forge 1.20.1 next to the mod. Servers that run it need every player to install it too. Files are published for Forge only, for 1.20.1, with 1.0.1 as the latest file, and the mod is released under All rights reserved, which means it is not open source.

Key features

  1. Ticking containment box

    A placed SCP-902 box ticks down a countdown, and whatever is inside must be destroyed before it ends.

  2. Paranoid messages

    Over 62 unique messages and events play as the countdown runs, expressing the paranoia of the holder.

  3. Document-triggered countdown

    Reading the document makes the countdown begin, so the box can be handled without starting it.

  4. Rare structure

    Containment chambers spawn only in snowy and frozen biomes at surface level, and the box is only found inside them.
