Is it my memory playing tricks on me or back in old days you could move while shoting ranged weapons?
Some how I'm unable to do it now and I kind of remeber that I could some years back. Was there a change / patch or do I just remeber some other game?

Thanks for clarification.

Meanwhile I have (re)discovered that you can do a dodge-roll (double-tap direction key) when shoting and that action interupst shoting and move you around. It is very effective and it is possible that this is what I remebered from my past play time.
