At 2:59 you can see it being used. It looks to be yellow like always…not blue from an other picture. This is the first time I have seen it being used so hope its new to you too.
Awesome
oh its not going to change will it.
It’s yellow again!
It’s either the FRD or the Promethean cannon since it looks like the same video the cannon was revealed in, also the lighting could mislead you. I can’t say for sure but that looks like the Promethean cannon.
Dang. I really liked the blue one
This is the second time we’ve seen the FRG…the other was in a Spartan Ops video I think, could be wrong, and there it was just laying on the ground.
At the very last second of it being used in the new video, you can see it being fired. It’s the FRG all right 
I think that was the Incinerator Canon.
