Use the arcade controls to move and eliminate enemies through the staged action route, then clear each round objective. Treat this World Games set as its own program when checking text, sound, input, or timing.

What is the best way to play Extermination (US)?
Confirm the World Games title screen, learn the first stage enemy entries, and keep movement steady while firing. Preserve the publisher and regional set in compatibility notes to avoid mixing it with the Romstar version.
