I think my success stemmed from building tons Crashers and the Missile
vehicles fairly early in the game, along with missile towers. The
meteorites drove me mad and almost seemed to be trying to keep me from
getting anything built - at one point almost destroying every thing I had,
but I was able to rebuild.
The Arm kept sending forces at me, but with concentrated effort by all of my
armed kbots and vehicles, I finally got to a threshold where the Arm
retreated once and for all, never to return.
The Arm's brawlers were probably the worst threat - so my early building of
missile equipt trucks was a life-saver.
What a game!
