Welcome to Librarium Online!
Most players us the bio rules for Tyranids and adapt there army to which ever force there playing but I was wounding how many have a hive fleet list to show your opponent. It states that if you replace the normal list you show have a new one of your own, you would also need this to work out if you could have Mutâ€™s. Its just that if you change your Gaunts as often as it seems from post on here you must either add a new species to you fleet or draw up a new list. This would mean you either have a new fleet for ever army in 40k or your fleet list is so big you would never get mutâ€™s .I would like to know how many of us have such a list(s) or is this the rule that is over looked by us Nids players !
If it lives it will be consumed
i use the biomorph rules, but i have been changing and adapting my army over the last 6 months, and i just change the old list, instead of keeping the old one the same. i don't have a seperate army for facing each enemy, i just make it adaptable to anyone. although i don't bother too much with mutants because i have 11 species, i don't need them because i have so many different and good things, that more than makes up for it. i don't change my gaunts, i am just thinking at the moment about have spinegaunts indstead of gaunts with spine fists and strength 4. so i don't change my list for each army, just have the same species for every enemy.
Its a bit of a pointless rule, unless you are in a campaign. Because you can simply say these are all my species for the battle, no one can stop you.
But in campaigns your hive list would be set and you would have to choose from them.
