There is an army list representing some familiar mecha available on the company website's downloads page. One could always find out for themselves how they play.
Look for the "'25 series assault mecha" pdf here; it contains early versions of some of the rules from the Skunk Works expansion book for players that don't yet have that product (and if you do, the rules in that book take precedence over the ones found in the army list document), along with some optional status markers for use with those units.
