The official PlayStation Turkey account tweeted out the PlayStation Plus free games for June, and it looks like Killing Floor 2 and Life is Strange. This came from an official PlayStation social media, so looks pretty legit. In fact, as of right now, the tweet is still up.
Life is Strange is an episodic coming-of-age story that includes kidnapping and time travel. A sequel was recently announced. Killing Floor 2 is a first person shooter that you can play alone or in co-op. There are waves of zombies.
