They where so awesome an from what I’ve seen they added alotta new arsenal but forgot about that one. It was so cool an fun just throwing them an hitting people with them an burning enemies. The path it would leave on the floor was epic aswell. The noise it made when it hit was like awwee man tell me that wasn’t what I think it was just like being stuck by the brute spike grenade.
From what I remember Incendiary Grenades were stickies that could do area denial. The Pulse Grenades from H4 seem to do area denial just fine.
Haven’t really followed up with halo 4 nice call though I’ll look into it 
I loved lighting people on fire in Halo 3… especially the crazy Marine in Floodgate.
Ah incineration grenades. Good times. Yeah, those would make a nice return I would think.
I enjoyed Flame-nading Vergil in ODST
I would like to see that and EMP grenades like from Headhunters. From what I’ve seen I’m not a fan of the Pulse Grenades so far. Would of made a better armor ability like regen.

Oh my god I know i’m glad you remembered that 
Astounding
I always loved the incendiary grenades. Yeah, the pulse grenade has the area of denial aspect to it but there is just something about lighting your enemies on fire.
I wish it would be back, especially for the new infection game mode. It would be so fitting…
I loved the wall of fire that it left on the ground and walls that prevented people from entering. The pulse grenades serve the same function in terms of area denial, but they more or less serve as a replacement for the power drainer. I think the problem with the fire grenades, is that they caused a ton of lag. Thus they were denied matchmaking privleges.
Flame Grenades were awesome. It was funny as hell scaring my friends with them in Custom Games. XD
