I don't know any of these mechs
Never heard of the spider tbh
They seem to be going down the FASA starter kit game box I have somewhere, so I expect to see Banshee, Whitworth, Assassin, Vindicator, Grasshopper, Panther, Zeus, Clint, Cyclops, and Hermes II before others.
Panther's the main Draconis light mech.
Vindicator is the main Liao light mech. Both mechs have PPCs as main armament.
GHopper is a faster, heavy close-range fighter.
Zeus is like the Battlemaster in some respects.
Clint was in MW2 Mercs, kinda sucks.
Hermes II kinda sucks too. It's a fast medium mech, like the clint, though better armoured.
Cyclops is a command mech.
Banshee is cool. The stiener variant is a better assault than the Atlas I'd say. Though many would disagree.
Assassin is a mobile medium mech, lightly armed but cool looking.
And the whitworth is a . . . . medium mech with some lrms. Like a smaller version of the archer.
