I really enjoy Dying Light, I've completed the main game 4 times with 4 different friends on co-op so it was getting a little easy for me as my skill tree is maxed out and I have some pretty hefty weapons.
I installed The Following DLC this weekend and so far I am enjoying it, it's nice to see some real DLC for a change with a whole new map and loads of new missions etc. Most the time when you buy a DLC it's just a couple of missions on an existing map and you're lucky if you get 2 hours playtime out of it. With this it seems like there are a good 10 hours plus if not more. The buggy is a nice new feature and I like all the upgrades you can do it, there is something satisfying about mowing zombies down
