Hmm I've tried searching around a bit to see if anyone did this but...

I'm looking for a few grenade's
1: Grenade will clear all terrain and units within a circle...(or explosion if you will) so it ends up looking like a crater.
2: One that kinda does the opposite. It creates cement (like the cement from the concrete(or foam) sprayer tool on the coalition or Ronin faction) in a circle. <--if this one can't be created, then it's fine.

explosion size would be bigish

In whitty's wonderful mods. Search it

Please try not to quote the poster above you's entire post, dragon. That's a lot of wasted post. Not to mention I had to look twice to find your contribution at all. -Duh

the top one i would say fits the description of maximdude's compressed air bomb pretty well.

1]UniTec Holy Hand Grenades.
Enable the Cheats.ini at indes.ini
2]Jericho Missile.
3]Crickets Pack of Mods. (try the Column Grenade or Insta Base Grenades)

Thanks for the suggestions, although I did find WWM's infinity void...thing is the probably the closest thing for the first grenade(after changing it to 1 stage and making the size a slight bit smaller...)

As for the second one I have checked out the insta base grenade but.. isn't it possible to erm.. "spawn(yes, I know a insta base counts as spawning but..)"..concrete.. like.. spewing out tons of it maybe for a set duration? (I've tried, how should I say this.. "mixing" the code for the concrete gun and my modified infinity void but no luck so far)

Then try Uber Filler Bomb at Shook Pack of Mods. Did you enable the Cheats.ini at UniTec Index.ini ? It has a "Holy Hand Grenade".

oh, hmm "uber filler bomb"? that sounds interesting...

(downloads and gets on cortex...few minutes later)
"so...all I do is throw this uber filler grenade...hmm"
(grenade activates and sprays concrete making my actor get pushed backwards)
"arhgh, must...throw..pulse grenade!"
(grenade gets sprayed and gets fired back at me)
"oh s........."

have I tried enableing cheats on unitech.. no.. not yet but I'll get to that. The uber filler bomb does fit my description but I may need to modify it a bit...so it doesn't throw concrete into my face from 50 miles away.

ahh.h....yess....... I forgot about the Ltm Digger Charge.
