HQ
Winged Tyrant
First off let's start with the Hive tyrant nobody likes any more. The flying one. The wings are costly, as much as for a
DP from codex daemons. If you are going to take wings, take an
VC for shooting and no other upgrades.
Use this guy to snipe side armor or lower
BS/
WS. Keep him surrounded by other flyers like Shrikes and gargoyles. Use harpies as decoys, nobody can resist shooting at harpies.
Tactics. It's all about playing team ball and not being a glory hog. A 4/5+ cover is nothing to sneeze at the (Gargoylecover/Venemthope) It can do a good enough number on transports, and can gimp a unit's shooting and fighting. Jump out for the kill when the moment is right, too soon and you are dead. Only assault with it if the game depends on it.
Other input: The all
DS/outflank army is great with 2 Hive Comander flyrants leading it. Give them old adversary and 2x
TL Devourers and have them throw out 12
TL S6 shots on the turn they arrive. (thanks Flingitnow)
Dual bone-sword regenerating Prime,
You know he is cheap, you know he is good, but you know what he does best? Stop things from being instakilled and taking hits on his 3+ save. For instance that missle launcher hit that would smoke a venomthrope gets put on the Prime, and he gets the 5+ cover, or that heavy bolter that would wound a warrior hits his 3+, yeah it's a real boner....
Tactics. As an
IC he can move from unit to unit as needed. The ability to stand erect when lesser tyranids would fall limp and lifeless removes the "weakness" of mid-sized Tyranids. Regeneration makes sure he can take it even more. Althought you can take two primes with bone-swords in one unit, this is overkill, and it's just not cool to cross bone-swords.
Elites
Lictors.
These guys get such a bad rap. They cant assaul when they come out anymore, but they pretty much go where they want. Take 3, put them out of sight for a next turn charge. Or put them by a
dev squad and brazenly fly that poor old harpy over, now they can shoot your 3+save lictors or 4+harpy, they are about the same points so you don't care. If you are too harpy (I mean chicken) to do that just deep strike them into your own lines to make an already strong advance even more powerful. Contest an objective while gone to ground or just draw fire from the real threat.
Y.Genestealers.
They get the ability to assault the turn they pop up, can boost
STR, attacks, or T. Also they come with a nifty 4+ save. They rock at coming out and rending a
dev squad or a small troop choice sitting back on an Objective. They also eat whirlwinds and the like with
STR 5 rending hits. An interesting combo I stumbled on is the fact that they can deploy normal style with the rest of your army. So if the table isn't looking to terrain friendly you arn't screwed.
Tactics. Deploy them with the rest of your army, Give them
FnP (from a tervagon). Now watch small arms fire bounce off of a T4 4+,
FnP, 5++. Who else can do something like that Plague marines and nob bikers. One is slow and the other cost about twice as much. With +1 attacks you double your base attack on the turn you charge, and with
STR 5 you can pen dreads and glance a raider. All this for under x2 the cost of a normal genestealer (before any upgrades). Without the worry of bolter fire or outflanking on the wrong side of the battle.
Other imput: You can also take some spore mine clusters to protect their terrain piece and have the added effect of screwing up
DoW deployment. Also, the Swarmlord loves them as he can give them Furious Charge and suddenly they have the option of
str. 6 rending attacks on vehicles. (thanks Mahu)
Pyrovore. Look at me I'm a flamer of tzeench, use me like one, my flamer isn't as cool though....get it
Troops.
Hormagaunts: these little guys are gold mines waiting to be unleashed. 15-20 in a spore pod will hold an objective. Drop them and bounding leap them to spred them out, or hide as many as you can behind the spore pod. 19 and a prime in a pod can be a hoot.
Termagants in a pod. Simple and fun. Spore pod+strangleweb+t3+pinning=fun
Genestealers....in a pod. Take 18 including a broodlord and a prime or two. Run to spread out. Take bolter hits on the prime(s) and brood lord and heavy weapons on the normal stealers. assault with whatever you have left. try to land somewhere where blast templates may land on friendly troops as well, or try to run into cover.
Tip. Model the spore pod as a basket with all your eggs in it. It wins big or putters out.
FA and Heavies and Army builds later. Input welcome.
