just watched the video, and as you said, it actually looks like there are bullet penetration... It might just be lag, but I doubt they would put laggy gameplay into a trailer...
Any new official words from devs?
where exactly do you see bullet penetration in this video? i see the opposite: no penetration - at about 50-60 sec in the video:
guy hiding behind a glass door and recovering.
i would appreciate to see 'consistent' penetration. being able to shoot thru wood but not thru glass seems unlogical, making differences between safety-glass and normal glass is also kinda weird (dont say they do that, just examples...).
but no bullet penetration at all seems to be a good way to go for me, clear gameplay rules increase the competition.
