Basically you use dice and tape measure to move around your troops and shoot. Different guns, models and tanks have different stats so you have to read a codex. There are so many rules and I can't tell you all of them so you will have to buy the rulebook.
Normal is from rulebook, bold italic subscript is from me. Quote "Warhammer 40,000 Rulebook page 51 in the rules section."
MONSTROUS CREATURES
These terrifying monsters tower over their opponents,
butchering all the enemies who face them and hurling
tanks out of their path. Greater Demons, Eldar Avatars
and Tyranid Carnifexes count amongst their number.
MOVEMENT
All monstrous creatures have the 'move through cover'
special rule (see page 75*). They simply bash their way
through trees and ruins!
SHOOTING
Instead of firing a single weapon, monstrous creatures
can fire two of their weapons once per Shooting phase.
They must, of course, fire both of them at the same
enemy target. In addition monstrous creatures have
the 'relentless' special rule (see page 76**).
Unless otherwise specified in their special rules,
monstrous creatures cannot go to ground, voluntarily
or otherwise. In addition, for a monstrous creature to
be in cover, at least 50% of it's body (as defined on
page 16) has to be in cover from the point of view of
the majority of the firing models. Also standing in area
terrain doesn't automatically confer a cover save to
monstrous creatures - the 50% rule takes precedence.
Cover for them works exactly as for vehicles (see page
62). As usual, if you cannot clearly tell if 50% of the
model's body is covered, modify it's cover save by -1***.
ASSAULT
All wounds inflicted in close combat by a monstrous
creature ignore armour saves, just like those from a
power weapon. In addition, monstrous creatures roll an
additional D6 for armour penetration (2D6 + Strength)
when attacking a vehicle in close combat.
*MOVE THROUGH COVER****
Some units of infantry are especially adept at moving
through difficult terrain. Units with this rule roll an extra
D6 when rolling to move through difficult terrain. In
most circumstances this will mean that they roll three
D6 and pick the highest score.
*RELENTLESS
Unlike common infantry, some powerful warriors like
monstrous creatures, jet packers and bikers can
advance while firing their weapons at full capacity.
Relentless models can shoot with rapid fire and heavy
weapons counting as stationary, even if they moved in
the previous Movement phase, and are also allowed to
assault in the same turn they fire them.
Note that a relentless independent character must still
abide by the assaulting limitations of any unit it has
joined, if the unit is not itself relentless.
***In all books written by Games Workshop, -1 save actually means 4+ to 5+ or something like that and +1 or +2 means 5+ to 4+ or 5+ to 3+ respectively (this is the books written by games workshop I've read.
****In the actual rulebook there is an asterisk here, which is explained in this paragraph from page 74:
The special rules marked with an asterisk (*) are
automatically lost by an independent character joining
a unit that does not have the same special rule.
These rules are also lost by a unit that is joined by an
independent character that does not have the same
special rule.
it all depends on what tactics you are relying on, as you should know each battle requires a different set of battle plans or stratagems. so really there is no really answer to this question. but think of tyranids as space orks they love there big numbers so if you have allot of tyranids, then the sheer number of your squads will over whelm the foe. good luck in your next battle
But, Tyranids do tend to do well in close combat
There are so many, you just need to read them for yourself.
I think it really depends on how many you have or how much damage they do
Depends. Do you like to swarm your enemies with hoards of terrifying monster and then shred your enemy with countless swipes of razor sharp talons and scythes? then maybe tyranids are your kind of Warhammer 40K army. However tough armies like the space marines will chew through your numbers with powerful ranged weapons and mighty close combat weapons like Deamonhammers and Chainswords. So really it all comes down to strategy and luck
If you are serious about Warhammer 40K you can only play Orks.
I say tyranids But it depends how you play them?
Maybe Tyranids? I don't know much about the Lizard men so it's basically a half educated guess
Defineitley 40K.
yes.
Uh, there isn't a T....If you could post an example that would help. IF it's in the stats it stands for Toughness If it's races it's Tyranids
AnswerAt the moment, GW do not make a set of rules for matches like that, so no, 40k armies can not play FB armies.== ==
Answer It depends on your preferences: When choosing an army consider its tactics/playing style or just if it looks cool. Do you like hordes of aliens? Then collect tyranids. etc.
Answer Warhammer Epic is much smaller than 40K. It is also cheaper.
Games Workshop made the Warhammer 40k Tabletop Game.
