Moreover, now that the serum has been created, some things have become much simpler to do.
For example, rescuing survivors used to require extreme caution, avoiding making too much noise for fear that if someone was infected, it would severely affect the entire team.
But now with the serum, there's no need to be so timid like before. In certain necessary moments, they can even grit their teeth and rush towards the zombie herd blocking the road! So what if you get bitten by a zombie! It won't be fatal; the serum can save you! There aren't even any side effects, at most just a tooth mark on your body!
As long as you're not completely devoured by zombies, even if only half your body is left, you can still be saved! Even if only half your body remains, the Hope Research Institute is studying prosthetics, potentially making you stronger than before with a mechanical body!
