I have no idea what Foster said, looking at it from a completely grammar/spelling/punctuation based viewpoint. 

"... this mean-" suggests singular- "-zombie-clones-" suggests plural multiples "driven by mechas" suggests that they are being controlled by anime mechs, not vice versa- "holding lightsabers, in space"- is fairly straightforward.


Although, completely realistically speaking, anime mechs controlling cloned zombies while holding lightsabers in space sounds like a really bad idea, one, because the anime mechs are probably bigger than the zombies, and two, because they might slash the zombie in half. And because legged robots don't work well in space.

Speaking of which, why would anyone even want to use a light saber in space? I mean, cool and all, but light saber versus an M1911 would equal the guy with the light saber dead. Common sense- no man's or machine's reflexes are fast enough to avoid or block a bullet at twenty times the range of a sword, when that bullet is going holy-shit fast. 

And with an M1911, you could control where you're going, when in space- with a light saber, you could, I guess, throw it? Firing a bullet is more effective, though.
