Quick and dirty background:

You are from a fairly shattered earth and have just repulsed the largest alien invasion since the "rain of death" almost 60-75 years ago. The Earth UN Forces are in full rebuild mode since the UN HQ was destroyed in the invasion HQ has been moved to a base on the Moon. Your job as is to play an interdiction force to round up and either naturalize or neutralize any remnants of the hostile invasion force left.

Current MI estimates put that at >10,000 starships with an estimated fighting capacity of 100,000 operational mecha.

Of course all resources are currently being used in reconstruction so priority to is protect outer world mining and salvage operations and allow for operations to be completed unmolested.

Your current Flagship is UN Spacy Corvette: Ramathorn
Your Squad is the: Flaming Ferrets.

Your Mission: Patrol and monitor all commercial shipping lanes, protect all resources gathering vessels and outposts. Meet and greet hostile remnants of the invasion and neutralize them using any and all means necessary.

I have got to ask! What is Sweat Talking?  I mean.. wow, is that like orcish love language?  "Your sweat is really nice as it glides down the brow of your eye"

Now that was just funny.  Freudian slip?

What is there to know... your a soldier... you pilot a 50ft tall variable wing fight craft changes into a hybrid and humanoid type mode...

You carry huge guns... your enemies are 50-70ft tall male/femail humanoids who are breed for war.. and want humanity destroyed.

P.S. I don't need crap about the source selection I know its not "technically" in the timeline, however its easy. Hell, if alternate timelines worked in Star Trek so it can work here.
