Okay, I have visited TODO page for modelling. You need 2x2 alien tank unit. Any ideas for it's design? I took quick sweep on Deviant Art and you can find many useless stuff, many ideas in general.
Currently I can't see in Wiki any kind of gathered ideas for this unit. So I'm starting a thread for that.
I guess we can go in two general directions. Tank per se and walker.
Nice design for tank, very alike Tau Army from Warhammer 40K. Not sure how many tris it would need, a lot of curves.
Or something like walker, similar to those from "War of The Worlds" by Spielberg:
It could be sweet to combine armor with "meat" parts.
Just few minutes on Deviant art.
EDIT
I have no idea how to make it below 1000 tris, but awesome design too
