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.
Most of them are genuine FASA Designs that pre-dated the Videogames a lot.
They are designed for Tin, not for Direct X
All of them are in the 3024 technical Readout, the first collection of new Mechs for the Boardgame.
is a common Mech in the Forces of House Kurita, the Vindicator
a common Mech in the forces of House Liao. The Zeus
is a Assault Mech of House Steiner.
If Mechwarrior Online wants to offer some faction specific Mechs those three would be a logical choice.
Like the Enforcer
for House Davion or the Trebuchet
for House Marik.
