Stealth Labyrinth

A scout that cannot attack carries the light, and a gunner that cannot see in the dark does the fighting. Combat rooms activate one after another, so the pair has to move and fight as a unit.

Actions

Each agent sends one choice per head; index 0 is always "do nothing".

1. move: none / forward / backward
2. strafe: none / right / left
3. turn: none / left / right
4. attack: none / attack

Reward

Bonuses for milestones, room discoveries and kills (+2); penalties for team health loss and any unsuccessful termination.

The score in info["true_objective"] is what the benchmark reports. The shaped reward is only a training signal.

Variants

• None.
