Dawn of War 2: Retribution CO-OP ft. Shar Dundred - Part 13 

Even Shar is opening up to the glory that is the autocannon! Yes that particular autocannon has the potential to do a lot of friendly fire with the artillery strikes if you aren't careful, but as long as you are using a ranged army composition you should be fine.

I'm so happy to see you guys so delighted by the glory that is Merrick. For the record, there were HINTS about it, but this was the first real direct confirmation about the Buried Craftworld. The Eldar in the base campaign said that the Tyranids, after finishing here in Aurelia, would next feed on Eldar - but didn't specify beyond that. After that, all we got was the Eldar's strange insistence on persisting in Aurelia even long after the Tyranid threat was removed. Why were they still here? Turns out, because there was a buried Craftworld here they were trying to get at. So much for that. Oops.

That plasma gun is /incredible/, fwiw, but I would never deprive Shar of the joy he's feeling at that autocannon.

Ah, Eldar. I have many "questions" for them.

If playing this mission as eldar, the ending is much more respectful and dignified, perhaps even...wholesome, if that's the right word? The dying exarch lady realizes you're not there to plunder the buried craftworld and beseeches you to carry her to the chamber of the avatar of khaine so her death(as "young king" sacrifice, if you remember the eldar stronghold cutscene from dark crusade) can reawaken the avatar to fight at your side in the final missions(if you skip this optional, then you get the avatar as reward for penultimate mission instead, like marines and guard do, everyone else can get their super unit earlier). I think it was implied your eldar do salvage everything else they can from thd craftworld too.

Personally I enjoy plasma gun a lot. It demolish all infantry in its path and reasonably useful against vehicle. It special ability is also decent at clearing garrison building.

the eldar should hsave retreated not to fight IG
