Like this bladed lizard Nero fights in the beginning of the trailer. Seems like a stronger variation of the lizard enemies from before.
There is this enemy that is apparently either invisible or transparent
This looks like the hotel from the demo but at night. Seems like the skipped section from demo.
This chicken boss seems to have some people (women?) on its back and they seem to move around.
V in the background doing stuff before they showed off the cameo/co-op system in the trailer.
This boss V fights
This massive bug enemy which might be the basic mooks final version
This weird tentacle enemy...maybe a boss
There is this enemy that is charging at Dante.
Lastly this could be King Cerberus. Its the same environment where Dante is telling him he is there to give him a walk.
So a good chance of a King Cerberus boss fight
