I admit it. I haven't played in a while.
I am just curious if there was a change to sappers at some point?
Do they no longer drop the turret thingies?
Seems like they are just used for building advanced defense without upgrades now...
Or have I just forgotten how the interface works?
They were changed, but you should still be able to build with them. On the bottom of the screen, towards the middle, you should see three coloured tabs: Yellow, Blue and Red. I believe you need to click the yellow one to build.
Sappers have changed roles to an Advanced Engineer.
