Cheers guys.
AnthonyR, thats the plan. Giant Mech combat. I'm planning on not even having infantry or armour support till I've properly worked out how the mechs fit into the system. It'll all be various sizes of Mechs with some small walkers in support.
My UNSC for instance use the Bulldog (like in your dp

) which will be a great start for supporting the larger Mechs... I'm thinking one Super-heavy, 2 size 5's and half a dozen Bulldogs at size 2. Once I'm happy with how the over sized Mechs run Ill introduce armour and infantry.
And thanks for the link Sarge. There's some great stuff there

It looks like picking up the starter pack is a great way to pick up a few good looking mechs cheap. Might give the rules a spin afterall. Any opinions on them or should I just stick to DSII?
