God mode: admin god [toggles on and off]
Fly mode: admin fly [toggles on and off]
Freeze non-players: admin playersonly [freezes monsters, etc. NOTE: named bots are considered players]
Slow motion: admin slomo #.# [1.0 is normal]
Before I explain how to summon monsters/creatures, REMEMBER this command: admin killpawns. Monsters are each considered a "player" so spawning too many can really bog down your server. If you ever get in a monster mess... this will get you out. It will kill all non-human and non-named-bot creatures (including the "Player" bots, below).
Summon item (such as a monster): summon Unreali.{name of item}
[Some of the "summon" commands will only work if you're on the ground with empty space in front of you. Others, such as the Queen and other larger objects, will only work if you're on a ledge with lots of open space below and in front of you.]
