Although Waldo had mostly cleared the nearby zombies, more zombies were attracted from farther away. Upon seeing Helen's reminder, Waldo was confident and dismissive, saying, "Don't worry, I've got this. No matter how many zombies come, it won't matter. There's nothing that can't be solved with a blast. And if needed, I'll use two blasts!"
After a moment of contemplation, Waldo added, "Besides, I've got plenty of ammunition. It's a perfect opportunity to practice my skills on these zombies. The synergy between a person and a tank takes some time to develop, after all."
Waldo was oozing confidence; he wasn't afraid of any number of zombies. It was a great chance to hone his abilities.
With that, the tank charged forward, unstoppable, obliterating zombies with each blast. Waldo fired round after round, eliminating the nearby zombies. The tank's path was relentless, and the zombies couldn't put up any resistance.
