Although faced with many enemies, most seem to be rather defenseless in the armor category. It appeared to me that even the largest tanks they threw at me were destroyed just as easily as a regular terminator. A 3D accelerator and a Pentium 100 are recommended to reduce any slowdowns during major fire fights. This game is definitely not without its share of glitches. The most noticeable would be clipping.
Enemies sometimes walk and shoot through walls.
Frustrating as that is, I found myself walking or driving through walls at times myself and then getting stuck. At that point all I could do was restart the level. Probably the most irritating glitch in Skynet would have to be the problem of enormous health penalties when falling only short distances. Many times during the game I have died from this problem. However, I was able to easily download a patch from the Bethesda website that fixed the problem.
