This sentry looks amazing and I think it should be added to the game but, How will it be built?
Will it be a new wrench acting like the Gunslinger which gives you the ability to make a Mini Sentry? Or for the idea I would like to see, A new PDA!!!
If its a PDA then will it have a new Dispenser and new Teleporters?
I want to end this with something but I got nothing so... :P
