what new creature you'll think to see in Halo?

What think I would see is new animals like an alien looking Frog or Tiger in the game or would it be like halo reach where you would be able to kill or interact with theas new beings or animals.

The first Infinite trailer heavily featured wild life. Granted, it might have just been a way to demonstrate the incredible graphics abilities of the new Slip Space engine. But there are tons of other ways to do that without rendering wild life. So I’d imagine there’s a good chance we will see the animals from the trailer, along with the ones in the HOD Ring Experience. If we could interact with them in Reach and even shoot the flying ones in H2, then it’s not outside the realm of possibility for us to have interactions with wild life in a more advanced game engine.

Flood infected wildlife.

blind wolves

Considering we have Rhino looking animals it would be cool if we saw Elephant looking ones aswell.
