The AI picks a target — the UFO if it’s on screen, otherwise the lowest alien — then simulates all 6 possible actions (left, right, fire, left+fire, right+fire, stay) for 80 frames each. It scores each outcome: dying is catastrophic (−10000), killing the target is highly rewarded (+500), any other kill earns points, wasted shots are penalized, and proximity to the target breaks ties. The highest-scoring action wins.
Tap Viz to watch the AI think. A green dotted circle highlights the current target, and a dashed line shows the AI moving toward it. Gray circles mark any bonus kills the chosen action would score along the way. The badge below the player shows the winning action.
