Intro Sprint is a rare card in The Tower: Idle Tower Defense that lets you skip through early waves quickly. It is designed for players who want to reach their highest wave faster without sitting through the easier opening stages.
Intro Sprint
Intro Sprint is a rare card that increases your wave count by 10 each time, for the first [x] waves or up to your highest wave. During this period, a Boss spawns every wave and you earn no coins. This makes it useful for rushing to higher waves quickly, though you sacrifice coin income while it is active.
