Blow up artillery turret pc

By default, you're supposed to hold R for a moment, then select dynamite from gadget slot (so either 3 or 4), throw it with RMB and then detonate it with LMB. I'll give it another look this evening, but the picking up part works the same way for all the gadgets.

By the way, things like rocket gun or AT grenades also are capable of destroying artillery turrets.

finally stumbled on to solution. == select four to bring up detonator .. rt mouse to throw .. center mouse to or left click to explode  thank you for reply
