Me and Mech#4 managed to beat hard Necron AI but it wasn't easy. Started off moderately ok, I pushed and stopped just short of entering the base, with Mech taking the middle route. But as I was barely preparing to field my first land raider, AI suddenly shifted gears into rape-everyone-with-tomb-stalkers mode. Yeah, I was losing my mind. And my whole damn army eventually, of course. I kept falling back, but at one moment AI decided not to push anymore, despite being in position to probably break through my last lines of defense and enter my base. Didn't pay much attention at that point, I'm guessing Mech distracted them and long enough for me to filed my first titan. The tides turned after that and we eventually won.
Then we played 3 vs 1 hard AI, orks + necrons + dark eldar vs. nids. Should be no problem, right?... Of course nids stomped us. I've made a mistake of being pop blocked early and while I held the line for a short while, eventually nids just charged through and nom'd my base. The bio-titan shoved up and destroyed Aklyon. Mech managed to field a titan of his own, but seeing it was no match against nid titan, decided to base-race. AI was smart enough to rush to defense and when DE titan went down, we just made a new game.
Next was same composition (or did Mech get CSM?) but against hard CSM and different map. Went much better, I've managed my pop with more care and rushed the AI. Didn't manage to quite finish them off, but we kept the pressure until this time I got the titan out and then we just crushed dem crazy humies. Also, that Waaaaagh! global is insane.
We also tried versing 2 hard AIs at the same time, IG and SM, but I was failing hard with Demons so that didn't turn out well for me. Other two managed to hold off for a while but then I left by mistake and game crashed. Next few games, this time just me and Aklyon was again me trying to figure out Demons, but we lost twice against 3 standard AIs so I was getting slowly pissed at myself. Then I gave up and changed to CSM and somehow we finally managed to beat the already mentioned desperate alliance. I was very close to being wiped out, but thanks to me building one and later second sort of giant defensive statue (don't remember the name right now) which turned out is moderately effective at killing stuff and with help from Aklyon, I've
somehow managed to build gate to dark mechanicus (or something)... only to figure out I am 100 relic points short of being able to make a single unit. Luckily, my brain was still working good enough to remember there's some RP research and I've held just a little longer to field that Warp Drake thingie. After that, despite loosing one, we eventually steamrolled over.
Here's one fine screenshot:
Notice the position of pylon and it's target on the map, down-left. That's a shot right across the map, bitches.
