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.
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.
Alex Gibson at IGCritic writes "he tower defense genre has been around since the earliest days of World of Warcraft 3 buts its popularity as a mainstream genre has seen a resurgence recently. Tower defense is now a universally played video game genre across everything from the current home consoles to iOS and Android devices."
