They were foes
like magical heroes
skulks came flying
marines arn't dying
the onos was big
until shot by a twig
dead the onos fell
comsumed by nanite cell
lerks souring above
destroying the healthy love
pis.sed were the marines (come on wordfilter)
started throwing magazines
the fades came in
circling in a ring
hated by all
jumping like a ball
comm got out
not giving about
trying to fluke
their anticipated nuke
but nothing worked
the marines were b0rked
they didn't fear
coming out a onos rear
kharaa has won
while marines were gone

Not bad, not good, the rhymes and the structure of the sentences could use some work, yet its better than what I can do . The beginning parts are better than the end parts I find.

Hehe really funny

I thought of sticking to 3 words per sentance but it worked out even less well so I changed a few of them. I'll probably make something with all sentances longer, thanks for your comments
