Well just started to try to take the ice cave for score, and man that parts intense. And hard as crap. I remember why I don't normally go in there when I just want to get as far as possible
The ice cave is more or less a cinch I think. It's those damn martian things at the end. 12 shots my ass
While it's on my mind:
Get the heavy machine gun before you enter the cave, from the helicopter.
About the hostages on the upper level, shoot up once and hit left to shoot diagonally, conserving ammo while releasing the other hostages.
Knife as many of the early abominable snowmen (abominable!) as possible. When you get stuff like the rocket launcher, it's 2 shots/yeti. Jump straignt up and aim precisely to avoid wasting ammo on the higher-level ones.
Ditto for the drop shot.
I think it's when you get Rumi, either that or the hostage in the mini jail when there is a snowman atop the refrigerator, try drop shotting as much as possible, break the ice, jump and knife/shoot the snowman and get the heavy machine gun as late as possible, again to conserve ammo.
When you get to the 7 or 8 or 9 at a time, use a few grenades if you have to. One thing I find very useful is playing it like a fighting game: be very aggressive. Walk up to the snowmen and shoot/knife/grenade then jump away, and whenever you are iced, remember to point up/right when hitting all buttons like mad to break free. You can pick off the top-level ones in the process sometimes.
After you get the elephant, learn to take advantage of the invincible jump off it, like any slug, and again don't be afraid to run up close. Try to get the diagonal shooting angle down and take out all the top-level zombies first. The ground-level ones are no bother really. Shooting the top-level ones later on from directly underneath is a good idea sometimes. Just watch for the odd falling one. The 30k gems don't appear until close to the end so worry not about having to dismount time after time. The 100 point bonuses aren't necessarily worth getting killed/zombified over.
I seem to escape the cave with all hostages and much richer in points 95% of the time using such tactics.
