Question is above. Would be cool if you could suggest "decorations" to me
Redstone
Pumpkin lanterns, and maybe a pair of cobwebs.
Spider webs
Trees would be practical!
Redstone, cobwebs, lanterns and pumpkin lanterns (as little as possible), execution devices (inspiration:
cemeteries, a dark house with a torture cellar and boarded up windows (signs), no flowers, continuous night (/ gamerule doDaylightCycle false), continuous thunderstorm (/ gamerule doWeatherCycle false, / weather thunder), Netherrack, lava lakes, jump scares, Herobrine, creepy signs (black wood, red letters, skeleton skull on top), (possibly: underground sewer system with Pennywise), etc.
That is the only good answer! Thank you very much. But is it all possible on Ps4?
Zombie heads?
Actually yes, except for the commands.
