New to nids old to 40k

[heude]

Hi looking to get into nids, I currently play necrons (only really started playing this year but been painting 40k for years never really had chance/people to play with)

So my gaming group is small (3/4 of us)

I seen a tyranid army in a local gaming event,it was a swarm list and I instantly feel in love with the tyranids,the guy finished 3rd as well and from what I hear he was a good player/ tactician although he didn’t seem interested in giving any advice or help as to where to start apart from the old line of “buy what you like and make it work”
Anyway the short of it is I have no idea where to start with building a 1k list that will eventually grow to 2k.
I like the look of all the tyranid models so no preference there,the group I play with have death guard,sisters of battle and admech
I’m not looking to be dominating everyone but I would like to last till turn 4/5 😂any advice would be greatly appropriated

The guy was right, but what you like. Our codex has some pretty good internal balance and just about any unit can work.

That said, our new codex is on the horizon. This means that all we know about tyranids will shift within the next month or so. If you can hold off any major purchases until the codex drops you can save yourself some time, money, and heartache.

If you do want to buy something today then focus on the evergreen tyranid units. Things like the hive tyrant, gaunts, genestealers, etc…. There is a new combat patrol box coming out, that’s a good place to start. It has a hive tyrant, 36 gaunts, and some warriors.

Between that and a big bug like a tyrannofex or exocrine and you should have enough to play a small game. From there you should be able to figure out what you like about tyranids. Then just buy more of that.
