Ultimates Game 4

Second day, seeded games from here. Having two wins and a draw I was expecting upper-middle pack competition, hopeful that I could get a win or two more on the board, I moved into....

Game 4
Mission: Scorched Earth – 4 objectives, every piece of terrain is either smoking (+1 to cover save if you’re in it) or on fire (Dangerous terrain). Either way, it blocks ALL line of sight drawn across it. Hope you don’t have lots of long range guns.
Spearhead deployment
Opponent: Tyranids
-Prime
-Tyrant with two guards
-Doom in spore
-2 x 3 hive guard
-Tervigon
-Gants x 20 in spore with some upgrades
-6 warriors
-Tyranofex

I went second...you guessed it, reserving everything. Once again there were a couple of objectives on either side of the table, so I was pretty confident the walkers would be able to find a target by simply walking on.
His turn one the Tervigon pooped itself with 14 gants that he then conga-lined across two objectives, giving license for the rest of his army to push forwards.
His turn two he placed both spores very aggressively and moved everything else forward, generally sweeping towards a central location.
My turn two everything bar one tank rolled on, so I castled up in one corner effectively, with walkers as far away from the hive guard as possible. What I didn’t really put together in my head is that the hive guard were completely unaffected by the bloody terrain rules.
My walkers shredded the entirety of the termagant squad down to one model, a single missile took care of the spore pod itself. I completely ignored the doom, since at strength four he was no threat until he ate some people....who were all in tanks...at the moment. In an unusual turn of events the fire dragons didn’t jump on the first target they could reach (this is an exaggeration, they normally jump on their predetermined target at the first opportunity though) since I wasn’t yet certain what I was going to use them on. I had one troop choice out of his four pretty much dealt with. I was trying to work for a good turn to wipe out the warriors in. I was planning on ignoring the Tervigon , just contest whichever objective it went for. The only other question was if I could get something into the termagant conga-line.
His turn three he immobilised a tank in my front line (one of the dragon tanks), not a good outlook for them with a tyrant and a bunch of other gear bearing down on them....all of which were invisible to my entire army due to one piece of terrain. The doom and the remaining termagant moved forward (not sure why, that termagant was a scorer if ever I saw one, I would have run that bugger into some smoky terrain)
My turn three i lined up the dump and dropped ten dragons and some missiles into 6 warriors with a prime....the dragons started bucking the odds and killed two. My missile took another one while another missile took out the dooms spore. My walkers butchered the doom. They were going to return nothing against the warriors who had feel no pain up.
His turn four he enacted a reprisal against my dragons and the ten exposed ones all died. Another tank dropped from the sky (fire dragon tank) courtesy of the Tyranofex (or tryranofex as i like to call them)
My turn four the five dragons in the immobile tank dropped out and prepared to die in much the same manner as their late colleagues (Contact the craftworld...we need more dragons...stat) and between them and a bunch of other shooting I put down the warrior squad. Now he had two troop choices left while I had four mobile troops left. My autarchs went around the back to reprise their role in my last tournament where they died taking termagants off an objective. The gants don’t kill them, the friends do.
His turn five he worked towards forcing a win using MC’s to contest and the tervigon to try to hold while the termagants conga’d the two, but he was exposed, with two objectives held by one squad of 14 termagants and his tervigon didn’t make the distance on the run. His tyrant buried itself in a squadron of walkers.
My turn five more walkers joined the tyrant dance in order to make sure it couldn’t break out and contest. My tanks closed on objectives, the two autarchs plus five dire avengers butchered the termagants in a compilation of shooting and close combat.
The game ended and was a win at 3 objectives to nil.
Good game, in my opinion he wasn’t careful enough with his troops, throwing them into the fight rather than conserving them, other than that I could have played better but got through.
