It would be sooo much better if you were able to create things and put them on your own planet and watch how it delevoped as you unlocked more things. Like a secret hideout for ghosts and ghouls and vampires. Then there were humans, assasins, heroes and other humans. And the population grow and there were zombie attacks sometimes! Lol but click + if you agree with me!
I found out something to keep him alive....
Grab him then do what ever you want to him * Inject hime with loads of mutant X put in implants anything* Then when his hunger is fulled to the top place food near him then let him out of grab. His health will raise without him dying! But you cannot let him out of grab before that!
