Congratulations! You just won the Scourge of the Federation Badge and 30 points!
Last mission was a battle of attrition...just had to wait them out. Many games on kongregate devolve into mere luck, but this game actually is all about figuring out the correct strategy for each mission (at least on hard...haven't tried the other difficulties). For that reason, 5/5!
On level 11, I apparently found some infinite loop. After I surpassed 100k points, I knew it'd never stop so I had to abort the shot: http://img.photobucket.com/albums/v107/ClayMeow/gravitee2lvl11.jpg
Thx, pooploops. I juggled and beat it easily like you said. I just don't like juggling because 1) I feel it's cheating, and 2) it means I have to actually pay attention the whole time. lol. Now to figure out how to conquer scenario 24. eek
