[cram]

I'm new to 40K so could do with some opinions on how this force looks please.

I have the Hive Tyrant, 3 Tyranid Warriors, 10 Gargoyles and 12 Termagants models so want these included.

1 x Winged Hive Tyrant. With toxin sacs and adrenal glands. Armed with monstrous rending claws and a pair of deathspitters with slimer maggots.

3 x Hive Guards with impaler cannons.

3 X Tyranid Warriors. Armed with deathspitters and boneswords.

1 x Trygon Prime with adrenal glands

10 x Gargoyles

12 x Genestealers

25 x Termagants. 13 armed with fleshborers and 12 with devourers.

20 x Hormagaunts

Totalling 1000pts.

So, good, ok or terrible?

Thanks Marc.
