Fairly simple build. Two ERPPCs for long range sniping and dual LPLas for close range defence. TAG provides targeting solution for LRM boats.
Just a personal thing, Why mount the PPC's in the Arms? The torso is slightly higher... But, if you must brawl, CT weapons it is. I would put the ML in the head, just save it for last, so you can still zombie around.
Yeah, I would probably do as Vergere suggests and switch the weapon placements. Not so much for sniping, as the height difference is fairly marginal and arm-mounted weapons let you use corners, but for tracking lights with the LPLasers in close. Don't see too many zombie Awesomes around , but an MLaser would give you a bit more punch in close. Personal preference I guess. I haven't had many issues running an XL in Awesomes (damn giant CT...), so I would maybe do a 300XL like so: A bit more speed, a bit more armour, and a bit more firepower. Just watch those shoulders...
