Stop taking Mechassault to be canon, Mechassault is a Battletech game in name ONLY, there are several stupid things in it, EG: 90% of the weapons don't work how they Should, most notably PPCs.

MECH NAME FACTS:
The Mad Cat IS called the Timber Wolf, Inner Sphere guys called it the Mad Cat because it looks vaguely like a cross between the Marauder and Catapult Mechs.
The Vulture is Officially named the Mad Dog.
I'll admit i got Masakari wrong, it's actually called the Warhawk.
the Nova Cat is called the Nova Cat, End of Discussion.
Variants of Mechs simply have number or letter after them, some atlas variants: AS7-C, AS7-K, AS7-D-DC, AS8-D, you should get the idea from that.

On the subject of clan mechs, there is a high chance that they will be introduced post launch in an expansion pack.

But my major issue with it is the lack of clan mainly cause it like star wars without the sith.

Mechassault is a dumbed down version of Mechwarrior, Not to say it's bad it just too easy,

mechwarrior was more of a pilot in a mech simulator, Mechassault is just a third person Mech vs mech shooter type game

But my major issue with it is the lack of clan mainly cause it like star wars without the sith.

Although this could just be me Fanboyin,
