You have to be ready to take what you need and run, because every step, every wasted second can cost you your own life. But every survivor knows one thing: something terrible roams in every corner of the planet, especially in cities, where mountains of dead bodies lie like they were created for that

(P2)That's why they change mechanisms and broken parts by taking them from dead bots. What about energon... Most of survivors kill each other to fill fuel tanks, or trick system by drinking their own energon.
Nowhere is safe, even if it's a good protected hiding spot.
