This was the first battle real battle I've played. Not sure if it was truly 750, could easily have been more. Here's what everyone had:
My team:
Me: Orks
Nofasse 'Eadhunta (Warboss)
25 strong Slugga Boyz
12 strong 'Ard Trukk Boyz
Trukk
Mega Armored Nob
That's all I had at the time, but the units my buddy had more than made up for this
My buddy: Necrons
Destroyer Lord
2 full squads of Necron Warriors
6 strong Pariah squad
3 Heavy Destroyers
Now for my Opponents, Dude with Tyranids and Idiot with Tau
Dude: Tyranids
Totally tricked out Hive Tyrant with more upgrades than it probably is legal to have
32 Gaunts
Carnifex (melee oriented I'm sure due to the scything talons)
3 Biovores
Zoanthrope
Idiot (because he truly is an idiot): Tau
Shas'O Commander
Crisis Battlesuit
2 squads of Fire Warriors, 12 strong each
A swarm of Drones (can't remember how many)
Hammerhead Tank
Odds stacked against us it seems? Well, you're about to find out.
Turn 1
Me and Buddy win the initiative, advance most of our units, I mount up my Trukk Boyz and move up, Buddy starts firing his Heavy Destroyers and takes out the Hammerhead
Dude starts firing off his Biovores, misses with almost all of them, nearly hits my Boyz but the Spore mine wasn't close enough to go off. Idiot advances his Tau.
Turn 2
My boyz go footslogging further, Trukk drives closer to the enemy and opens up with the Big Shoota, taking out 2 Fire Warriors. Buddy advances and attacks, brings the Carnifex down to 1 wound. He activates Nightmare Shroud with his Lord and his Pariahs to Deep Strike next turn.
Dude fires off his Biovores again, managed to land a Spore Mine in my mob of Boyz, but the strength of the blast only took out 2 of them. He managed to take off the Big Shoota on my Trukk with a shot from his Tyrant. Idiot had ran off to God knows where so we skipped his turn, his loss.
Turn 3
My boyz keep advancing, now here comes the funny part. My Trukk had a Reinforced Ram, so here's what it did.
-------- <---Fire Warriors, both of those lines are Fire Warriors
--------
I ran my Trukk to Tank Shock the first squad of Warriors, they made their Leadership saves but still had to pull back. Then I let out my Trukk boyz and they charged the second group of Warriors, effectively rendering all of his Warriors useless

. Buddy got his Deep Strike in, he ended up right on top of the Shas'O, and threw the greyskin into the meat grinder. Then an ability that Pariahs seem to have called "Massacre" allowed them to go after another squad in the same turn, so he went after the Drones.
Dude charged his Carnifex into my footslogging boyz, and after an epic battle with Nofasse, old Nofasse got his head bit off (but after that battle da Painboy sowed his head back on, now he's good as new

) But he ran off after that so he did nothing else. Idiot complained that we skipped his turn, so we told him "Either you're here to play or you're not, stop whining." Just for that, we skipped his turn again.
Turn 4-Last Turn
My Trukk turned around to go pick up that MegaNob who was Slowly and Purposefully making his way to the battle. Trukk Boyz kept on beating up the Fire Warriors. Buddy finished up the Drones and Massacred to the Gaunts, his Heavy Destroyers took out the Zoanthrope and finished the Carnifex.
Dude came back only to find himself being decimated by Necrons. Idiot started sniveling again and concedes. Dude also concedes, doing whatever he can to slow the Necron's progression with his annoying habit of doing whatever to win.
This game was rather weird I know, our opponents weren't always there. They had better smarten up if they even hope of playing in a tourney.
Btw in the turn progression, the units I didn't mention didn't really kill anything in those turns. The ones I didn't mention were usually advancing. Well, on Buddy's part, advancing.
So the game ended with most of our team's units still alive. Buddy didn't suffer any casualties. I'm honestly not surprised.
Victory results:
1 cackling Necron player, who basically annihilated two armies on his own
1 happy Ork player, I found this game satisfactory because I was on the winning team
lol
1 disappointed Tyranid player, because he didn't win
1 whiny little 11 year-old kid, serves him right for waving his ratty Tau stuff in my face
I feel like I just typed out an essay
