I came up with this somewhat arm-heavy build based on the new quirks: The AC/5 is for the quirk. There's no downside to this variant not having a Laser Duration quirk since the PPC and MPLas wouldn't benefit from it anyway. * The PPC can be swapped for a LPLas (same weight) if desired. * Disregarding the AC/5 quirk in favor of giving a larger autocannon the benefit of the two general ballistic quirks is certainly a valid option. An AC/10 will fit by dropping two heat sinks and either changing the PPC to a LL or changing the two MPLas to MLas. An AC/20 is completely incompatible with this build, as it requires a standard engine. Also there are lots of XL275/XL280 configurations already listed on the forum, so those remain options too with no money wasted on the engine. Suggestions welcome.
