Look in top left corner you can see three other types of grenades besides the frags he is using. Obviously one of these will be a plasma but does anybody have any opinion about what the other two may be?
Flame nades…could they be coming back?
or Spike grenades?
maybe a new UNSC prototype grenade…
cryo grenade possibly?
i will laugh if anyone suggests stun or flashbang grenades
the third one looks like fire to me the forth type is no visible…
Freeze grenade, anti gravity grenade or trip mine.
cOLD…kinda.
the white diamond/square could be like a small flair
that armour looks pretty badass
Well, obviously Frag and Plasma grenades are in the game. The icon for one of them just looks like a plane diamond, so it could be a placeholder. The other one looks like a spiral or a swirl of some sort. Can’t really get any more information out of them than that.
I don’t like how green the DMR’s scope and ammo counter is.

Anti-flashbang grenades… instead of blinding you it darkens everything around you so you can’t see. 
I’m wondering what the AA is that the player has maybe its the new forerunner vision
One looks like a star(maybe), flash bang maybe?
FRag, plasma, fire, forunner or spike
I’m hoping for flame nades.

If you look at the cube next to the map im gonna guess that its the armor ability icon.
It should be a forerunner grenade which acts like a mini Halo Pulse and vaporises the enemy in range 
I only see 3 types of grenades. I see 3 options on the top left of the HUD with the currently selected grenade type being enlarged just to the right of it. Notice how that first of the 3 options has no picture? And notice it has the same number as the select frags? Seems to me that when a grenade is selected, it enlarges itself on the HUD.
