Overview

VepMod adds a new enemy called Whispral to the game REPO.
This unique enemy causes hallucinations in the player it attacks, making them see fake copies of their teammates.

The mod records players’ voices during the game and uses them to make hallucinations more convincing.

The Whispral

Description

The Whispral is an invisible creature that moves through the level searching for players.
When it detects a player, it approaches and attaches itself to them for a set duration.

Behavior

1. Spawn: The Whispral appears in the level
2. Idle / Roam: It wanders around the level, exploring areas
3. Investigate: It investigates sounds it hears
4. Notice Player: It spots and locks onto a player
5. Go To Player: It moves toward the detected player
6. Attached: It attaches to the player for ~240 seconds
7. Detach: It detaches and moves away
8. Leave: It leaves the area

Interactions

• The Whispral can be stunned by throwing objects at it
• When stunned, it releases the player and all debuffs are cleared

FAQ

No. Fake Players only exist for the affected player.

Q: How can I tell if a teammate is a hallucination?

Some clues:

• Strange behavior (stalking, sudden fleeing)
• No response to voice chat

Q: Does the mod work in solo?

No. The mod requires multiplayer, as hallucinations copy other players.

Yes. The mod records voices during the session and replays them through Fake Players.

• Throw objects at it to stun it
• Wait for the attachment duration to end (~240s)
• Stun yourself (pressing Q works)

Audio samples are stored temporarily during the session.
