I like this map, it has a great deal of potential and is quite fun in areas.
However, I think that in it's present state (whatever is released, beta2 I think) it has one fatal flaw. It has 2 routes between bases, above ground and underground. Movement between the routes is only passable by Dretches, Grangers, Basilisks, goons and a partcularly lucky mara. The adv. goon can pass through the doorway to the "medical area" that the tyrant can't, but a good human team will build a base there anyways. It's difficult to snipe, can only be attacked by tyrants through one small door with a huge window next to it (so you can see them coming/healing up). When humans build there, none of the "heavy armor" can pass either way. Depending on which side of the far side ladder the aliens build their base, S3 aliens will be unable to defend there own base AND attack the human base.
I very well may be woefully mistaken, and it could be an excellent gameplay idea for a map that I just don't get (it wouldn't be the first time

). It is something you'll want to watch for.
I really do like this map and seriously look forward to the next version!
