Double Tap

Follow a matching hit with another shot.

Adds a follow-up shot when the named tower attacks a matching threat. The follow-up deals less damage than a full-strength shot.

When to choose it

Choose it when matching enemies are staying within reach and an extra hit could help finish a survivor.

Limits to remember

A follow-up needs a valid target in reach. It does not permanently double the tower’s firepower.

Read the tower portrait and any pictured infected role on your selected card. The ability applies to eligible towers of that tier for its designated wave. A new card replaces the previous choice; these are temporary abilities.

Merging into a different tier changes which cards apply. Check the tower you have after the merge.

Try this in your fortress

Watch for the first impact and the extra shot, then see whether the enemy survives.
