*pb is 54... just beat it - now 53 :)
mate at school got 40... he's very good at the combo's of tricks
i simply do alot of up & outs whilst flipping, then get to the ground and to the pole vault and an up & out - 960x3 per time - usually can do about 3/4...
if you do that right, you will be guarunteed to get at least 20K per jump with 3rd stage rocket
you guys are all complaining about the game taking too long to finish...being on jump 143 and not being done... upgrades being too expensive... i cacn beat the game in less than an hour and my pb is jump 64 to beat both bosses and have bought everything.
Try doing flips to get instant x2 multiplier...
If you need help getting the hard badge, get a tank, a missile, the golden gun, and as many nukes as possibe. And as plasmakiller said, use your gun when you are going really slowly. Ammo packs are really useful for your golden gun when you are heaps far into it!
