Sentry Beams would be so much more fun if ...
I've been experimenting with elaborate Sentry Beam set-ups with predetermined angles (ie. beam bounces a few time to hit a hologram cube behind/above raider which would let in guards from the back). It's soooooo satisfying when it works. But it is very inconsistent, due to how the tracking factor throws off beam trajectory 50%-75% of time.
I think having a mod for Sentry Beams, which would turn off tracking (or possibly just make them shoot in a straight line upon detection) would make for some very creative/fun set-ups.
It would also solve the problem with how easily Sentry Beams tend to destroy other traps and sometimes themselves due to tracking unpredictability.
