Hah, not particularly. I based this off the bog standard disposable Gespensts you get in the early parts of OG1 on the GBA, before I started looking up actual fluff stats, and those sad little machines get naught but the split missiles, a machine gun, the JET MAGNUM... and a nice looking design, heh.
Anyway, a couple of arena fights has this thing doing fairly decently. Insofar as ranged weapons go, the Gun's "weaksauce," as they say, but a full salvo or pair of half salvo split missiles has been damaging or destroying at least one mech per fight.
The JET MAGNUM on the other hand might be a bit much for a low-end mecha -- of the five or six times I've gotten close enough to use it in the last two battles, all but one of those was a 1 hit tko -- and that one was a miss against a speeding wraith (Which got magnum'd later on in the fight, hah.).
To be fair, it was an awesome miss though, as the mech went from JET MAGNUM swing to off the end of a cliff in the same action. Crazy blighter apparently took a flying leap at the Wraith... which is pretty in character, heh.
Pretty in line with my usual hackjob mecha designs, honestly. Next up is tinkering with transforming mecha, hohoho. S'going to be interesting to see if I can get limbs to 'split'...
