Here’s my method for infinite zombies as requested by popular demand. I got 42k points on this round, but with this method I have scored over 44k points as shown in the beginning of the video. My lasers are strong because I have spent a lot of time upgrading my equipment. Be sure to work on your equipment facility in order to keep your laser damage bonuses as high as possible. If you need help with the equipment facility, I have a video explaining that as well. Happy gaming!
