Looks like we're getting some advanced tactics from the minds down at Defense Grid 2. This week's new technique: not building your fancy laser towers directly in the path of the encroaching enemy. Here to help narrate these developments is General Fletcher, the man who elected to have his conscious eternally fixed in a giant planet-sized defense system with enough firepower to stop an alien invasion. I'm just waiting for him to slip up and read a "1" in stead of a "0" and accidentally initiate the Annihilate All Mankind Protocol. He is British, though, so he'd waste everybody very politely.
