I didn't encounter a lot bugs. The bugs I encountered, are pretty minor, not major. So far, no major bugs/issues spotted.
1. Try do a small explosion yourself and your camera will be moved backward, finally showing Amanda's model character. Only hands and legs.
2. Samuels kills a synthetic. Hours later, returning back to the location and I see the synthetic "alive". He does animation such as idle, scratching head, like normal but you cant attack him and he will not respond/attack, no matter what, he is standing there, "alive" but ignores the environment. Was demonic scare for me...
So far, no bugs prevented me playing.
