Injection Invaders

Shooter

Reject Every Payload Before It Lands

Prompt injection is not a chatbot nuisance - when an agent has real tools, an injected instruction is remote code execution. Injection Invaders puts you behind a signature-verification cannon against descending waves of injection payloads. Verify them out of the sky before the formation reaches your line.

How to Play

  • Move: left/right arrows or drag the cannon along the bottom.

  • Fire: space, up arrow, or hold - your beam rejects one payload at a time.

  • Bunkers: the Policy Server barriers absorb fire from both sides and wear down; a Policy drop rebuilds them.

  • Drops: catch capability tokens that fall from destroyed payloads - Signed (triple beam), Governance (freeze), Memory (+1 life), Policy (rebuild).

Clear every payload to advance. A HARVST mothership prowls the top for bonus, and returns as a tougher boss every third wave. Six waves holds the line - a victory - then Endless+. Three lives; if the formation reaches your row, it's over.

Why It Works This Way

Every mechanic maps to a real principle of agentic AI security.

In the game In the real world
Your beam rejects injection on contact Cryptographic tool signatures reject unsigned or tampered calls at runtime - deterministically, not by guessing.
Policy Server bunkers absorb the assault Zero-credential policy enforcement stands between the agent and every sensitive action.
The HARVST mothership never truly leaves Harvest-now-decrypt-later is a patient threat; post-quantum encryption is the answer.
No power-up stops injection alone Injection demands layered, cryptographic defense - not a single filter.
