The game was a 2v2 annihilation game. Greyknights/sisters + Space Marines (custom chapter) VS Orks +Necrons. 4000 pts per side. Since the necron player only had about 1500 pts, the ork player helped by bringing up himself to around 2500. Orks won the initiative and chose deploy first go first. We seized the initiative. I can't account for all the forces on the field but I can point out some specifics.
Necrons : 11 model warrior squad (x2).
Monolith
Nightbringer
Necron Lord with res orb and the shadowcape thing (deepstrikes)
(2x) 5 man pariah units.
A deep striking scarab unit with disrupter fields.
Orks : was a bit iffy on the chart but I ignored it for the sake of the game. He had a lot of heavy support options and we allowed it.
(2x) zaap cannons
(2x) kannons.
(3x) looted wagons- all with boomguns
a 3model killa kan squad.
2x warbosses. 1 had powerklaw, not sure what was on the other.
2x 30model mobs of boyz.
1 30model ard boys mobs.
5 model burna squad
He had a nobz mob, with painboy, eavy armor, cybork bodies, big choppas, and truck.
Huge grots mob of 30+runtherds.
6 deff koptas.

Cassius
4 Tactical squads. 1 squad has plasmagun/plasma cannon. 1 with a Lascannon. 1 had a powerfist sergeant and 1 had a meltagun. All had meltabombs. They took 4 razorbacks as transports with 4 hunterkillers. 2x lascannons, 2x assault cannons. :
Ironclad dreadnaught with drop pod and 2x hunterkillers.
Land raider crusader with hunter killer, cronus, storm bolter and multi-melta.
Termis with missile launcher.
Predator with lascannon and h-killer.
I had some extra points from the gray knights player since he didn't have enough for 2000.
Gameplay:
Round 1. We seized the initiative (Remember I'm marines). Our turn: In the shooting phase I destroyed all but 1 pariah. I immobilized and shook the monolith. We destroyed 1 boomgun, 2 zaap kannons, 1 killakan, and some grots + boyz. I shot off 7 of the 8 hunterkillers.
Their turn: Pariah ran off, some of the sisters got shot up (for this I have no idea how many models died, but not enough to cause issue). a lot of shaken results on vehicles and the ironclad received a stunned result. 1 Razorback with lascannon received shaken result. The C'tan tried to harm my razorback but it lived.
Round 2: I finished off the pariah earning another killpoint. i destroy the trukk carrying nobs, and another looted wagon. The grots mob is eaten up by the destructive force of a crusader and some other such stuff. for shots hit and wounded the C'tan, but he saved all of it off. Some boyz were shot up (insignificant number died, I think 4-6)and some necron warriors took a few more hits. My shooting phase throughout the game would take longer than the opponents entire turn..
Their turn: The Necrons had their revenge. Monolith destroyed some gray knights (jump pack squad) The Necron Lord deepstruck his unit of warriors behind my land raider and with 20 gauss rifle shots... glanced off every weapon but the storm bolter. 2x Hurricane bolters, an assault cannon and a multi-melta. I couldn't believe it. The waaaagh was called and Sisters got assaulted and were wiped out mostly. The Sisters
HQ "died" but had some special rule of coming back. In anycase...
Round 3: The gray knights terminators with their psyker leader deepstruck in. Cato and his command squad got out of the
LR. A razorback with a combat squad, Cassius and his combat squad (sgt + powerfist, flamer, 3 bolters) got out as well. Assault cannons shot up some more lootas (3 kills this time) and the Nobz squad (no deaths this time) but were rather ineffective. The Landraider tankshocked the lootas in an attempt to make them rout off the edge of the board. They passed their morale check. Cato, the command squad, Cassius, and the combat squad, poured fire into the necrons before preparing to assault. before assaulting, there was only 1 warrior and the Lord with 1 wound left.. The killakans were assaulted by the Ironclad dreadnaught and the C'tan ignored most of my fire forcing to save only once. I'd attack the other necron warriors, but they were in the far corner behind several buildings and i just couldn't reach. In the assault phase I destroyed both Killakans and I destroyed both necrons (lord and warrior) in assault.. Cato performed a coup'det'grat on the Lord for an easier wound and the command squad slaughtered the necron warrior by about 10 wounds. This would have been a clean killpoint but the lord got to try a we'll be back the following turn which means the warriors might get up too but only if the lord got up. the 2 engines assaulted the C'tan along with the assassin with his poisoned weapon. The engines were all but slaughtered with one having no weapons left and immobilized. The battle did come at a high price for the c'tan though as he had only 2 wounds left near the end of it. The assassin ran off via hit and run and the turn was ended.
Their turn: The orks swiped away the last bit of resistance from the sisters, Necron lord failed to stand up. Scarabs deepstruck behind my line. Nobz squad moved closer to the building with my two heavy weapons in it (missile launcher and lascannon). Deffkoptas came in via outflank. both coming on the side with most of my stuff. My razorback with assault cannon was destroyed with an explosive wreck result. my other managed to live since it had moved and was thus harder to hit. My othe razorback with the assaultcannon was immobilized and the assault cannon was destroyed by ork kannon fire. with more bloody mayhem on the horizon, the orks moved into position. Ard boyz moving under the building I had one combat squad. 1 boyz mob got to the rooftop (by running) of another building my plasma gun and plasma cannon were in. My Razorback was rammed into by a gunless Looted wagon and (to the wagons dismay) it was completely ineffective.
Round 4: In the final stages of the battle, many things happened. The Razorback (lascannon) that had arrived in reserve dropped off its combat squad and fired at the last looted wagon, destroying it. The combat squad that came out of it shot and assaulted ard boyz (destroyed 2 models with pistol fire and moving into assault. Killed none x__x). The Land raider attempted to run over the lootas again in tank shock but they managed to pass leadership again. So in the shooting phase the landraider (with cronus) repaired the assault cannon and shot up the lootas with that and a storm bolter.. removing four models. Another C. squad came out of the other Lazerback and shot and assaulted the deffkoptas nearby. The survivors of the explosive Razorback jumped out of the wreckage and attack the deffkoptas responsible. Failed to deal sufficient enough wounds to destroy all of them though. Cato and The command squad turned around in an attempt to destroy the scarabs before they reached the predator and lazerback. The powerfist/flamer combat squad and Cassius turned about trying to fire 2 hellfire rounds into the God. Both attempts failed. The c'tan was assaulted by the Gray knight termis and it resulted in the C'tans inevitable death by the hands of the emperors champions. Gray knights with psi cannons shot up the boyz mob near my plasma weapons and saved me. 1st Kopta squad used hit and run and escaped my laserback group. (there was only 1 left in that squad.)
Their turn: The necrons only had a few warriors left (just barely over the line of phase out). They were moved behind a wall whilst the monolith nearby shot its payload into the greyknight termis. They survived luckily. The nobz / painboy squad decimated the combat squad from the wrecked razorback and proceeded to the building nearby in consolidation. The koptas ran/flew off. The ardboyz were still locked into combat and eventually destroyed the combat squad it was facing. Scarabs assaulted my combat squad. and were deadlocked.
Round 5: Command squad shot up the nearby Nobz* (this is a change. I realized I wasn't specific enough. Did only 3 wounds though =/ removing 1 model.) 3 lascannon batteries went into them as did a missile launcher and 8 doubletapped bolters.
FNP Nobz with a 4+/5+ saves...yeah they suck sometimes. In anycase. I picked off 2 more necrons with the missile launcher and the missle launcher from the termies. Chaplain turned with powerfist sgt and went to stop the nobz mob. He never reached them. Ironclad kills off the other two Deffkoptas in assault and the landraider managed to hit some more lootas, killing 2 more.. (couldnt run over them this time though =/)
Their turn: The scarabs managed to do a few wounds to the combat squad in assault but it ended up being insignificant. The Monolith managed to blast away more gray knights. I believe the last jump pack squad.. but I'm unsure. The ork warboss with a powerklaw tried to assault a lazerback.. but couldn't reach it. The nobz + painboy assaulted my combat squad. 5 valiant warriors were slain doing little to even hinder the charge of the mighty greenskins. The other combat squad with the ard boyz was wiped away as well. 1 scarab fully died in assault (due to losing the assault and then taking the fearless save).
Game ended at the end of round 5 due to the roll.. and the killpoints were...
