I'm playing Mass Effect I, the PC version.
On the Equipment screen the instruction say to "click the Filter Tabs" to switch between types of equipment. I don't see any Filter Tabs. The only equipment I can see is weapons and there's also a box to toggle whether or now I want Shepard to wear a helmet.
The manual is completely useless. It doesn't show where such things as the mysterious Filter Tabs are and it doesn't identify the icons used for the various Biotic weapons. It doesn't explain how to do things like boost Shields. I don't know how to do any of those things.
