Just like the 2008 original, Defense Grid 2 is the kind of game I can sit down with intending to play a quick 30 minutes, only to look up and find three hours have passed. This brand of extremely addictive min-maxing tower defense retains all the strength of the first game and adds a new layer of complexity that promises to extend replayablity - even if it can’t repeat the original’s unexpectedly emotional story.

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.
