Save all of the natives to recieve a slightly different ending.
When the Telescope becomes available in one of the Native City shops, don't buy it. It gives you a lousy first-person view anyway. Later on in the game when all your equipment is taken from you, your first objective is to get your equipment back. When you do, the Telescope will be automatically given to you because the game assumes you bought it earlier! When you get back to Nativ City after being given the Telescope, go into the shop where it is sold and look at the Telescope--with the Telescope! You just saved some Nooties!
Whenever you talk to anyone and Kya crosses her arms, you can rotate your head. To do this just hold down the X button, and rotate the Left stick and her head will tilt in the direction you tilt your joystick.
