They use a special weapon powered by the same chemical that makes up the monsters. It’s extra effective against them. We saw them use it back in the beginning of the first chapter.
On Friday, my buddy Travis started a great new comic, Ellie Starling’s Very Long Walk! It’s only just starting but it’s really interesting and has a lot of character so far. I’m already loving the main character. If you like Monster Pulse I’m sure you’ll like it, since it’s also about kids on adventures inspired by video games. Check it out!
