I guess this is another expacted build. This would make a good zombie though. I see this as a slower, but more meaty version of a Zombie Hugger. Trying to go without AMS also. XL Version:
I play with a similar build. I have an STD Engine and 4 x MLas and 3 x SRM6 with Artemis. A good mech for close fights. Also heat is not a big problem at all. Good choice !
Hopefully once they fix the hitbox issues on this mech this will become a much more viable option. As it is right now I feel like a barn door with missiles.
It is a walking CT with weapons! I am thinking about shaving most side torso front armor off. Since right now you get cored with your front side armor relatively in tact. Other than that, this is quite a decent mech. Only thing missing is ballistics.
Here's my version; By dumping the 2x arm-mounted MLas, I give myself a hefty shield-arm to help guard the CT, and massively improve my cooling efficiency. This lets me equip more ammo, an AMS, and most importantly, Artemis 4 on my SRMs.
