Well, I can't model or code or anything, but I grabbed a bunch of pictures of (about) 5 or 6 alien calsses from SST (No plasmas, that'd unbalance the shit outta the game). I'll post the pictures upon request of a few modelers and coders who decide to take on the project. Just be sure to finish before 1.4

EDIT: Okay, there was a request for the pictures so here they are. (hosted by the lovely

Here's the new and improved EGG:

Different stages of a warrior bug:

Four warrior bugs(notice the last picture would be the taunt for all warriors, and that it's the second stage or third stage of a warrior bug; Warrior; Tiger; Royal Warrior; X-Bug...me thinks):




A cliffmite:

A blaster:

Two hoppers:


The Queen (I'm thinking the Overmind's gonna retire and leave the spot open for this beast):

And a (BABY) plasma bug (these ones would spit over their heads infront of them, projectiles would be slow but have splash damage-S2):

Also, a baby tanker would be nice (flame throwing scarab-S2 or S3).
