Hmm, I play both Nids and Orks... (I'm trying to resist the Hive Mind!) Well depending on what they bring there are a whole bunch of Nid stomping list opportunities (obviously) but when your playing an 8,000 point game there isn't much you can do to "prepare".
When your facing almost every unit in the Tyranid army you can't really counter his unit choices; you need to counter his game plan...
When I assemble Apocalypse lists (with my orks anyway) I divide how-many ever points I'm playing with into 2 separate lists; two different "task forces". Each list would have a different objective in mind, so would generally vary in styles (ie. #1 Heavy Support, #2 Objectives) Or whatever role I needed them to play once I saw the battle field, and the scenario.
Tyranids can be truly frightening when play Apocalypse games. In fact the manager of my local store absolutely crushed an SM list by completely outflanking em' (if you want to see the battle report pictures go to (*http://www.heroicrealms.com*
) and look for them on the galleries (if you have troubles finding them just let me know) Nids can really take advantage of Apocalypse abilities and tactics, along with their own; and can really overwhelm your opponent .
Ok now for the list:
Hmm... I'm wondering how this is gonna happen... I'm used to playing smaller Apocalypse games, so I'll either add to some of my 4,000 or 6,000 lists, but they're sort of made in my style, which is a little subtle to operate. Just post back the style of list you were sort of leaning towards and I could come up with some concepts (or if I ignore the rest of today) I possible could have it done by tonight.
So stick around,
