Basically, one of my favorite BJ-1X builds (get it, "21" - I crack me up) in a MUCH beefier package. STD engine instead of XL, 158 more armor, 4 jump jets, and more control of the MPLs with the articulated arms. Tough guy engine with decent speed for a 75 tonner, good alpha, decent cooling. Probably not the best option to leave that beautiful high mount Ballistic empty, but it's an ultra sturdy MAD. Plus, it Zombies.
Fixed for engine cap... Wish I would've added the Hero onto the pack. Even with the smaller engine cap, the BH looks greasy!
I'll actually go for 7 MPLasers instead, just for the uniform laser duration, cool down time and the simplicity of weapon modules
