Had completely forgotten about this until you mentioned it in the entry mecha thread. Had intended to do something, but my current character only got polymath and mecha engineering like two missions ago. Anyway, let's give this thing a shot...
...Oh dear...
... well. I'll refrain from posting the text file; suffice it to say I used entirely stock pieces: That is, I took a Gaunt body, ripped everything off but the weapon mount, and started copying and pasting Shard thrust pods onto it. This creature could be built entirely in-game, for one willing to farm low-rep missions (or buy shards) long enough. There is now a ludicrous number of pods (33!) on a single machine, its max speed is a 615 (Interestingly, it's 615 regardless of if the jets are space or flight...), and since there's an Acid Sprayer stuck in the body mount, it's still eminently capable of murdering things violently. Max speed doesn't seem to be cutting off; more pods = more speed. I guess I could get better results if I alternated propulsion pods with overcharger pods, but... eh. Stats are currently -3/-7/-8, but, yanno', Acid Sprayer. Any of the LINE weapons would probably work just fine. Could rip out the computer of a Luna II and get the targeting down to at least -4.
Well, I could post the design file entry, but it's at 341 lines in notepad++, hah. Gonna' see what this design philosophy does to a runner ^^
EDIT: Changing it to a hoverfighter gets another 40 points of max speed. Making it a hoverfighter 3 (Bluebird), cuts max speed down to 591, but at least it's still stock pieces, heh.
EDITDATWO: Hrm. Overchargers provide a bit of thrust in and of themselves, apparently. Sticking a pair of legs on that design nets a max speed of 408, but it's still skimming, jumping, and flying in space. Maybe an arachnoid... ... arachnoid still jumps. Bah!
