Summary: The co op is quite hard with only 2 players. especially if you don't have any upgrades in the game. The game is very sci-fi, has some interesting features that you can use in the game, like a loose cover system and being able to heal your team mates well across the room but, the difficult has only normal, hard and expert. THEY FORCE YOU TO HAVE TEAMWORK IN THIS GAME. No patch will ever come out to fix this and sadly the developer is making a new game.
Summary: Syndicate plays a little similarly to other FPS games, but it's got enough going for it to make a worthwhile play-through. I can't comment on the co-op as I have no interest in it. The setting and graphics in Syndicate are phenomenal. The story is kind of average but the priority in this game is certainly the atmosphere and action, which it does with excellence. 5/5 in those departments. The dubstep/electronic music is alright.
Summary: Firstly this game uses origin. Which I would have no problem with normally, but this is the first time I've had trouble with their DRM. A lot of people including me have had issues launching the game. The problem lies within Origins DRM apparently. This was the only fix I had been able to find that had many people confirming, http://www.starbreezeforum.se/viewtopic.php?id=1280&p=3 , seems to have stopped working.
