There we go!
The challenges weren't as bad as I thought they would be. I spent maybe 45 minutes on mission 18 and that was the one I was stuck on for the longest (I was too afraid from the hammer guys at first, so I always ended up fucking up. Then I grew some balls and bashed them to pieces using the pincer baldes, and after that the rest was just a walk in the park). I also need to say, mission 17 gets the prize of shittiest VR mission ever.
I think I'm done with the game for now, I won't have to time to get all the S rankings on revengeance because of uni, I'll do that later when I have time.
Overall, I really loved the game. It's dragged down by the camera and some annoying as hell enemies (looking at you, mastifs in small rooms), but as a whole it's still pretty damn fantastic. I'm impatiently awaiting MGR:R 2 on next gen consoles, it has the potential to be something exceptional.
