Runner

Runner Rush trades toughness for speed. It reaches defenses faster than a Walker and attacks at a shorter interval once it closes in. A small gap in coverage can become a problem quickly.

What to watch for

Watch for a fast approach in a lane you were treating as safe. Runners are fragile compared with standard infected, but their quick strikes make late reactions costly.

How to respond

Keep dependable damage on the incoming lane. Respond before contact and avoid leaving an exposed tower while waiting for the perfect merge. Tactical support can buy breathing room when fast enemies break through.

Why it changes the board

The Runner puts pressure on timing. The strongest future tower is not always as useful as a defense that is ready right now.
