OK, Battle report with first intro of superheavies /w/ D weapons into my local gaming group... We were just sort of messing around to see what would happen. It was an 1850 game.
I brought
Transcendant C'Tan with Transliminal Leap, 6d6 krak missiles per turn, and D Weapon Hellstorm Template
Imhotekh
Royal court /w/ 4 stormteks and Veiltek
Firestorm Redoubt /w/ BS3
3 units of necron warriors, 2 in night scythes, 1 to occupy the building.
My buddy didn't feel like proxying a superheavy, but tried to take some things knowing I would be bringing one. He took (not very exact)
Some Ultramarine tac squads in rhinos / w / melta
Tigurius
Grav centurions
Buff commander
Like 3 squads of various Crisis suits (missiles, melta, etc)
I got first turn, he kept Grav Centurions in reserve so he would be more likely to be able to get first shot off with them eventually on my C'Tan.
My turn 1:
I jumped C'Tan forward, nuked 1 large crisis squad with 25 krak missiles, and incinerated 2 rhinos (1 of which had tigurious in it) with the D weapon. My lightning squad teleported forward with Imhotekh attached and wrecked another rhino.
NOTE: Rhinos might actually be VERY useful when fighting superheavies... as far as I can tell, a D weapon can only burn the rhino itself, it doesn't hurt the occupants. So it's 35 points for a 1 turn D shield.
His turn 1:
He posessed the C'Tan with Tigurious, but his D weapon (16" long template) wasn't in range of any good targets of mine. I had nothing else on the baord So he fired 21 krak missiles at my lightning squad /w/ Imhtokh, but Imhotekh tanked like a champ and soaked up most of the wounds. He then fired a bunch of stuff at my C'tan and the lightning squad. It's really hard to hurt something that has T9, 3+ armour, 4+ invul, and FNP with normal weapons. He did 1 wound to it and killed off most of the lightning squad.
My turn 2. Jump the ctan over the remaining rhino, exploding it. Jump the reemains of the lighning squad out to no man's land b/c they don't matter anyway. SHoot 23 krak missiles at another 3 man crisis squad, killing it. I had jumped to arrive near tigurius's squad & the other tac, so fire the D weapon, and kill all but 1 grunt marine from both squads.
His turn 2: his army is devoid of anything that can really hurt the c'tan except for the centurions. They didn't arrive from reserve, so we called it, but then we just pretended that they Did arrive to see what would happen. They did another 3 wounds to him (it's still hard to get through the 4+ invul plus FNP). So we pretended that they had killed him to see waht would have happened. He exploded and did a strenght 10 AP2 hit to everything within 19" of him. This explosion killed all of the remaining marines, the 3rd crisis squad, and 2 of the centurions (who had gotten a little too close, about 17" away).
My turn 3: 20 minutes had elapsed. My other friend who was looking on started trying to convince me that we still had enough time for me to drive home and get Lords of Waterdeep and get in a game. I tried to convince folks to play again /w/ proxied superheavies but was not able to drum up interest.
