So what do you think about this? 343 before relasee was saying alot about how they had to tons of downscaling with the things they wanted to do with the game, and I think this is a good indicator of mow much they did have to downscale.



First up is playspace onboard the Infinity.


A new type of Promethean enemy. Looks like it could have been somthing between a knight and a crawler, which could have been pretty cool.






Some kind of Forerunner Weapon Platforms using what seems to be an early design for the phaeton as guns


It seems 343 was going to have this whole modular system as the overall mechanic for the Promethians in general



It'd be interesting to see how the weapons using this system would work.


Warden may not have been the only boss planned


In fact I think this thing called the Cavalier is what eventually got reworked and down scaled into the Warden. It looks identical to the concept art for the Warden found in the Artbook. More of the artwork and the name "Forerunner Mimic" sugests it may have been able to have multiple forms.

I remember saying that they put the most they could do with the Xbone with Halo 5. If this is true this is disappointing.

Armour concept art:

If you look in the artbook at the actual concept art for the armor designs they all look about a billion times better than the in game stuff.
