Path of Exile, a favorite free-to-play RPG has popped off and on the radar more than once since it first rose to popularity in 2013. It stuff has not quiet in June this coming year with the launch with the Legion expansion. 

But from a bit of a wait, Grinding Gear Games is back using the new Blight update. While the update hosts several tweaks, changes, and additions, the star on the show could be the new Blight challenge itself, which plays out just like a tower defense game.

Sister Cassia is attempting to stop the spread on the mind-controlling Blight by destroying Fungal Growths. When attacked, the Blight commands infected monsters to guard it. The monsters mindlessly keep to the Blight's tendrils, only attacking foes directly of their path. Unusually though, so you'll want to build defensive towers to use each monster's specific weaknesses. For each tendril lane you defend, a chest will show up with your rewards.

Even though tower defense modes are generally a sign a development team is running short on ideas at this time, the update itself looks pretty fun. It's also something looks like it might get out of hand incredibly fast, essentially in The trailer above.
