Halo 6 Incendiary, Smoke & Thermite Grenade

I was thinking about this what if Halo 6 had an extra layer to current Spartan abilities, in which every Spartan in Multiplayer would have special type of Grenades. This special types of grenades like Incendiary Grenade, Smoke Grenade & Thermite would give every player a more realistic and would add deeper fresh and new gameplay for Halo 6. For example using a Incendiary Grenade would cause an area to get incinerated for about 35 seconds to 1 minute, any player going thru that area will loose massive shields. Smoke Grenade would give players an extra way to hide and get out of bad situations. Thermite is a powerful incendiary device used to produce intense heat through a chemical reaction and destroys anything it touches Within an area, these special type of grenades realistic Spartan ability would create a more dinamic Multiplayer experience for Halo 6 something we have never seen before in Halo. Here are pictures of how the grenades would look for Halo 6 Multiplayer.
