The list I took was (1250pts):
Tyrant + scytals x2, old adversary, armored shell, regen, implant attack, toxins, paroxysm, leech
Tyrant Guard x3 + lash whips
Tyranid Prime + boneswords, regen
Hive Guard x2
Tyrannofex + rupture cannon, cluster spines, desiccator swarm
I won't go into the details of choosing deployment and first turn. All you really need to know is there is one objective in the dead center that is worth 3 battlepoints at the end of each player turn starting turn 2, and each killpoint is worth 2 battlepoints (or 3 if its from the player who deployed opposite from you).
My Game #1 opponents were:
Smitty: Eldar - Eldrad, 10 wraithguard + lock, 4 jetbikes, and 3 wraith lords with a ton of str6 shooting
Gabe: Marines - chappy, 5 assault terminators, 10 assault marines, 10 tactical marines, 10 tactical marines, land raider redeemer (I may be off with the numbers and gear, but you get the idea)
Zack: CSM - lash sorc, greater daemon, Noise Marines, 10 marines, 15 raptors, predator, vindicator, rhino
The pre-game: Well I made this list to take the center and kill whoever comes close, so that's the plan. I'm really worried about Smitty's eldrad list with all those instant death shots and str10 CC, but I can't play a 4 person free-for-all defensively with Nids. I get to deploy first.
I set up a passive assault with the genestealers on the center, but my genestealers only get 2 rends, 1 of which is shrugged off as well sas the normal wounds with fortune and an invuln on the warlock. We lock in the middle which saves me from shooting, but I was hoping to get a little closer to the killpoint. At least Smitty lost the objective for now.
On my right flank, Gabe and Zack are comtinuing to wail on each other.
During my next turn, I plow my deathstar into his and he counters with all 3 wraithguard. I fail to land paroxysm on the big unit and we exchange blows for a few rounds. In the end, he has more attacks than me and I lose to attrition. I lose my tyrant and guard, but my prime remains alive to contest the objective.
So we tally up the points and end up with:
Me: 17 (15 from 5 player turns of holding the objective, 2 from the jetbike kills)
I take first from my table and wander around to check other results.
The post-game: I had mixed feelings over the next hour. Yes, I took first from my table, but players from other tables were up to 29. Looking back, Gabe's full on attack on Zack denied Smitty and I half of the action and killpoints. Smitty's list is my kryptonite with psy defense, insane buffs, and nearly everything was t6-8. However, I built mine for survival so we cancelled each other out a lot, leaving a bulk of my points from holding the objective. Overall, it was a win, but a very weak one.
