Turn 3 (I'm on a roll!)
Teleports - da da da DA DAH! Termies magically appear next to n/spinners and Scorpion (told you GROOV3R hated eldar artillery), with no BMs damn them.
Strategy - Marines.
Unsurprisingly, 1 fm of termies charged the n/spinners and engaged them in FF (this is a constant source of annoyance for GROOV3R, all those +1 EA CC wasted). Wasted attacks or not, the tanks are swatted from the sky like flies and the termies consolidate within support range of the 2nd termie fm (no casualties either, unsurprisingly).
Retaining, the 2nd fm of termies charges into FF with the Scorpion. 1DC is taken, with another from supporting fire, and the tank is wiped out on resolution. No marine casualties, again

Ignoring the triumphant terminators for the moment, Eldar proceed to rip into the reaver. Vypers (obviously auditioning for spare shining spear slots), advance into support range and strip the remaining shield off the titan.
GROOV3R asks if I want to retain, as I hang my Vypers out to dry. I don't, so the reaver decides to teach those
annoying annoying little things a lesson and charges into FF. 4 vypers instantly get squashed underfoot or booted out of the air, but surprisingly the vypers do 1DC of damage in return. Vypers lose the assault and another gets trampled on resolution. Remaining vyper scampers back to Eobj.2, assured of all the Guardian ladies they want when they get back to the craftworld.
SC tacs go back on overwatch, wondering if the guardians are going to show (they really don't want to, but..)
hawks pluck up the guts and charge the reaver. However, they should have stayed at home, as they get the poo beaten out of them for no return - sole surviving hawk flits back to where it started.
obj. camping tacs do something uninteresting.
n/wings ground attack the reaver, taking another DC, leaving 2.
This is where the order of events gets fuzzy, largely because I can't remember what order things happened in at the marine TNH objectives.
Anyway, falcons advance to within 15cm of the blitz and unleash at the reaver - taking something like 7 hits, finally the titan is overwhelmed and comes crashing to the ground. BTS to eldar!
Sometime around here, the guardians decide they better turn up and do something, so advance out of the gate into cover. Taking o/watch fire, they lose nothing (yay to cover saves and RA) but take out an SC tac dread for their troubles.
2nd lot of tacs in the woods go for glory and charge into FF with the guardians. Unfortunately, they forget how nasty wrath constructs are and get ground into paste, being wiped out on resolution. Eldar lose 1 w/lord and a couple of guardians in exchange.
Now that the battle is nearly won, the 2nd aspect warhost decide it's time to show their faces and air assault the Scorpion destroying terminators. Striking scorpions pour out into base contact and dire avengers hang back at FF, along with the vampire. Rolling 20 dice at 4+, eldar score 9 hits on the terminators, wiping out 3, including the librarian. Not to be out done, the terminators strike back, taking out all the striking scorpions. Eldar win the assault and the last terminator is gunned down, running away, whimpering with fear, crying for their mummies (I don't like terminators). Broken aspects withdraw so that they're within 15cm of both TNH objectives.
And I think that was the end.
Rallying - everything rallied bar the swooping hawks (won't be taking them again, back to washing up duties for you) to give:
Eldar BTS, blitz, TNH
Marines 0 (guardians were contesting 1 TNH objective)
What a surprise! My first full game of epic and I won

Probably won't happen again, but I'll relish it while I can ÂÂ

All I can say is that by having air superiority I could attack the reaver as much as I liked, finally destroying it and taking the BTS, then air assaulting the terminators that threatened my TNH. Once down, the 3 tac formations couldn't really do much and just one single unbroken guardian formation stopped them from claiming any objectives.
Very much like the flexibility of eldar, though they are fragile and, as the first turn showed, prone to failing activations. Won't be taking swooping hawks or rangers gain though, not for a little while at least.
Thanks to GROOV3R for a great and nail biting game - round 2 looks as if it'll be even better (and bloodier)!
