What makes a good Tyranid army?
A lot of gaunts, an equal mix of the two types, never take a
unit with less than 15 gaunts in it or it will be destroyed before
it reaches there lines. take a venomthrope the 5+ cover save it
gives has saved my units more times than i care to imagine. make
sure you have a synapse creature from each force organisation slot.
once your opponent gets smart and tries killing all of those you
can never have to many. once you have lost a unit to instinctive
behaviour it can be hard to get it back. lastly it is always good
to have a carnifex and tervigon to soak up some fire and replenish
your units, when you take a tervigon always give it catalyst feel
no pain on a large unit of hormegaunts is amazing the look on your
opponents face as his shots fail to kill them is hilarious.
