Played once and it was good won in 30 days. Second time I did on open gov't easy and it keeps going without stopping. Entire country free of virus and it has no end in sight. Time to neutron a few cities :-)
I've tried that level with the 2 guys above me 20 times. I even tried what Kilorth said and that is to wait before hitting the springs. I looked at the youtube walkthroughs. For some reason on my computer they don't even go up the last hill to explode themselves like they do on all the others. BUG!!!
There's a bug on the lvl with the two springs and the box. the AI controlling the other two characters refuse to climb all the way to the top of the hill so as to detonate the bomb. (http://www.youtube.com/watch?v=YNWMH7qvrac it works on that video at 3:14 but not on mine)
Fun Speedball-like game. Almost reminds me of the Jet-Pack fueled speedball for C64 (can't remember the name?) It too also liked to lock up lots of times. This one needs to be slowed down a little bit because even on the C64 one when the ball would change hands you'd have a split second to realize that you now have the ball. In Crunchball I could throw the ball three times without realizing I even had the ball seven of those times.
Beat the game on easy on first try. First 1500 spend it on maxxing speed cannon tech and canon power, laser power, factory speed. Drop down 10x speed canons and 4x factories before game starts. Then drop down 2-3 lasers and a few more canons. Don't bother with Offensive weapons at all. Next get frag maxxed out and then you can do 5x speed, 5x frag, 4x lasers. Remove the factories after you have plenty of cash and you can put down more cannons. Next max lasers and factories then last is max out power canons. Easy win.
