So here is my first attempt at writing a battle report. I hope this works out the way I hoped. This is a 1500 point Seek and destroy (gamma scenario).
Oh and for any helping hints on the Tyranids list for my friend it would be greatly appreciated. This was his first game with the 'nids and he seemed to do well but rolled really crappy.
In this BattRep, I was playing Raven Guard Space marines, geared to take down alot of infiltrators, but I didn't realize that things changed alot from the old 'Nids book to this new one. I was dreading hidden setup lictors and infiltrating genestealers.
Matt, my friend was playing 'Nids. He was in for a "trial by fire" first game with his tyranids. I would've included digital camera pictures but ALL of his models are unpainted and I know how up in arms some people can get.

-H-1 is wiped off the table fromthe combined shooting of Frag missiles from D-2 and rapid firing from B-2.
-Epistolary attempts another shot with FuryOTA, but I rolled double 6 for the psychic test.
Tyranids Turn Two:

-H-2 rolled two 1's and a 2 for their move through cover, and 2 inches on their fleet. H-2 was still partially in cover forcing them to roll difficult terrain again to assault, which failed.
-the last gaunt still in T-2 remains lurking in the open.
-the 2nd Carni fired off his 2 TL-devourers killing 3 snipers in S-2.
-the last remaining warrior in W-2 fired his barbed strangler into B-1 killing 2.
-the 1st Termagaunt brood fired into the 1st Scout sniper squad only killing 1 sniper, the gaunt's were also out of assault range.

-Sniper squad 2 and the Devastators rip into the last 2 warriors in W-2 clearing them from the table.
-The Vet.Sgt. falls in line from B-2 and fires off his bolter along with the Snipers from S-3 into brood H-2 clearing them from the table as well.
-All 4 Missile launchers and 2 of the bolters from D-2 hit home on the genestealers killing all but 2.
-The Epistolary uses his Storm of the emperors wrath on the last 2 genestealers finishing off the squad.
Tyranids Turn Three:

-The unit of gaunts (T-1) that was wiped from the table attempts to enter the table but fails their LD check for Movement. They end up fleeing off the table immediately.
-The remaining gaunt from T-2 comes out from lurking but fails his LD check, so he falls back 8 inches.
-The gaunt brood T-3 also fails their LD check and runs 11 inches.
-The 2nd Carnifex pumps his shots into the Epistolary but all wounds (4) are saved. -The remaining warrior from W-2 fires into the S-2 snipers and kills another marine.

-Carnifex 2 fires everything he has at the Librarian and again fails to hit home. The carnie tries to move into assault but is approximately 8 inches from his mark.
Marines Turn Five:

-The Epistolary uses his Storm of the Emp's Wrath on C-2. Needing a 6 to wound i was reluctant it would work but with it being AP2, I had to try. IT WORKED! Now the Carnie only had 1 wound left.
-T-1 was picked off from the Hvy Bolter from B-1.
-C-1 was railed by the remaining squads and left with 2 wounds.
-The Epistolary assaulted C-2 and killed him, then rolled a 6 for his sweep which led him into C-1 removing the extra attacks from his assault in the next CC phase.
Tyranids Turn Five:
No Need for another picture here. Matt, the tyranid played admitted defeat after I used the force weapon on his last carnifex killing it. He didnt even attempt bringing on the last gaunt broods.
All in all it was a fun game, for me atleast. I told my friend that alot of the game was determined by terrain placement. If more area terrain was placed in the center, the game could have gone completely different.
