CalBear:
There are a couple of main interface screens in Redline. The first one is obviously the walking screen. Like all first person shooters, you see your hand holding your gun out in the bottom center of the screen. Along the very bottom is a row that indicates which weapons you have available and which you don't (the ones you don't have are in shadow). The bar also shows how much ammo of each you have left. The order of weapons in the row corresponds intuitively with the number on your keyboard you have to press in order to switch weapons. On the bottom right side you can see how much health you've got. Picking up certain items like the radar or targeting computer will activate other parts of the interface. For example, with radar, a circle/grid appears in the bottom left that shows the position of enemies and targets relative to you. The targeting computer will highlight targets in your main view in red.

The driving interface is somewhat similar. You're given the choice of first person or third person view while driving a car. We found the third person view easier to use because it gives much greater visibility. Either way, you always have radar available in the car, and it's in the same bottom left hard part. The right bottom corner contains information on what weapons you have available and how much of each weapon you have left. The car interface also gives you a crude car outline to represent your armor status on each side of your car. Green means a healthy armor level. Blue means that you've taken moderate damage to that side, while red obviously means that you're about to blow up if you take another hit on that side of your car. There are also stationary turrets in the game, but these give basically the same interface as you would get if you were driving a car.
