GR: After going free via Microsoft’s Xbox Games with Gold program a few months back, Defense Grid has remained somewhere on the fringe of my mind as a pure tower defense game and nothing more. When it comes to wasting loads of enemies in order to keep your base of operations or your particularly valuable MacGuffin safe, Defense Grid provided every element I could have asked for even in the face of my own obvious love for another tower-defense brand in gaming.
The Nerd Stash: "Everyone loves setting up killzones and laying waste to waves of enemies, so here are our picks for the best tower defense games ever."
It's also free to try on the mobile headset and Oculus Rift.
Tower defence games have become incredibly popular on iOS and Android devices over the last few years but they are also incredibly fun to play on your PC.
I loved Defense Grid. Can't wait for the sequel to ship!
