Vampire Survivors Game Killer Guide: Unlock and XP Halt

The short answer: defeat the final enemy in Cappella Magna

Game Killer (0) is unlocked by defeating the final enemy in Cappella Magna. It stops experience gain, turns Experience Gems into exploding projectiles, and makes every Treasure Chest contain at least three items.

This card replaces normal leveling with a different way to fight. Be careful when selecting it before a standard build is complete.

Unlock steps

1. Progress through the base stages until Cappella Magna is available.
2. Enter Cappella Magna.
3. Defeat the stage's final enemy.
4. After the run, confirm that Game Killer is unlocked.

Use the base-stage progression guide for the route to Cappella Magna.

Reading the effect

• Experience Gems no longer provide experience.
• Collected gems fly toward nearby enemies and explode.
• Every Treasure Chest contains at least three items.
• Normal weapon and passive-item growth through level-ups stops.

If the card is selected at the beginning, the starting weapon and other acquisition methods must carry the run. If it is selected later, first confirm that the current build can survive without more level-ups.
