No i haven't... but like the model in the picture posted the scat has missle tubes on it's left and right torso..
Is MW4 the only one you've played? Everything you say seems to be based on this fact.
The model in the picture posted is of the MW4 version. The original TRO art
, which MWLL's Shadowcat was based on, does not have missile tubes in the left and right torsos.
Even the Mechwarrior 3 Shadowcat
is based on the TRO art, and does not have missile tubes in the left and right torsos.
