My heavy walker the (bull-)DOZER: Weapon Groups: 1: M-Lasers (linked) 2: UAC5 3: LBX10 4: M-Lasers (chained) Why no XL Engine? Cause I had the feeling to die pretty often cause one torso site was crushed. It's not a fast mech but it can bite pretty bad and has good armor. It can get a little hot sometimes but in that case you still have the LBX10. cheers Philoczek
