Busted Hump Ski Resort
Rocky Mountains, Colorado
You can cause avalanches on either side of the hill - just take out some of the trees (top or bottom) and eventually you'll hear a roar and see the beginnings of the avalanche on the ridge. This is where the Bearhug move comes in useful - drop several of them in the path of the avalanche and when enemies try to run, they be pinned in place. Squish!
Cable Cars: Good points - you collect lots of powerups on your way up the hill. Bad points - you're a sitting duck and likely to be on the business end of everyone else's homing weapons. Furthermore, the don't stand up to much punishment and any passengers will be uncerimoniously dumped on the hill when they're destroyed, often upside down!
Use this to your advantage by waiting until opponents get in the cable car before hitting them - something like the Crater Maker should do the trick.
Note also that cable cars regerate and they are tough enough that they still function even after the building at the top and bottom have been taken out.
The snow generators are generally dotted around this level and created clouds of snow that can obscure the view - drive through them to throw off vehicles on your tail.
Not so much a feature, it's worth pointing out that both this level (and the similar Winter Games) are unique in that they slope sharply from top to bottom. This requires a few new strategies. Firstly, the better vantage point from above is a benefit for homing weapons, as well as making it harder for you to be hit yourself. If you're under attack from above, one risky option is to drive towards your opponent, as many times their missile will overshoot, turn and impact on the ground behind you. Getting up the hill can also slow your progress - make sure that you have a store of Interceptor Missiles and use the Afterburner to speed things up.
Weapons & Powerup Spawn Points
As well as the cable car path, the best area is probably around the cabins - as well as the cable car buildings themselves.
