Good news, Truce and I are working on a whole new sentry bot.
Not if I'm scripting it 
But in all seriousness, since I'm not using Rot's AI system (I cannot stand copypasta, even though it may mean I re-invent the wheel constantly), there will be a lot more functionality that can represent that of TF2.
So...
It will the same (but improved) sentry without letting it use Rot's Zombie mod?
Be sure to add compatibility to TDM and Rot's zombiemod though.
As long as that will be in there, i will be happy. :)
Have fun with it both of you.
Also, from today on, i agree that sentries have to be static stuff.
(I am de-modifying it again.. It moved too much. :/)
