So I've played a bit of Quantum Break and here's some early impressions.
Quantum Leap is about a guy who time travels to try and change the course of history. Oh sorry, I must have gotten my titles messed up, but this is ESSENTIALLY the plot. I don't want to go into too many specifics of the plot because honestly I'm about 3 hours into the game and it's still slowly revealing stuff to me, but all I'll append is that time itself is breaking down and some people are trying to fix it while others are simply preparing for the inevitable sh*t storm that comes with doing such things.
The gameplay is a 3rd person shooting style game that I feel can be best equated to the original Mass Effect, where you have standard guns as well as manipulation powers to give you an edge. It is in essence a cover based shooter, but not the refined version that we saw in Mass Effect 2. Instead it's that airy, something isn't quite right floaty combat that the first one had, where movement is difficult and firing outside of cover turns you into a bullet sponge where you pop out, take as much damage as you can, then go back to recover before repeating. Also, remember how in Mass Effect you had to upgrade your powers over the course of the game until you unlocked others, so by the time you're 3/4ths of the way through you feel like grand sorcerer with a gun? Well QD doesn't really have that. Powers are basically thrown at you at random spurts and before you're done with Act 2 you basically have acquired the ability to stop time, block bullets, dash into bullet time, fire balls of time energy that kill people, and also "paint" your enemies so you can see them better. You can still get upgrades by collecting pieces of light throughout the level (they're not called that but that's basically what they are) but all they do is just make those listed powers better with longer range or quicker cool down, as opposed to an actual evolution of the powers akin to what you'd see in a game like inFamous or Prototype. It just feels like too much too quickly.
And I'd be remiss to not mention the television show that accompanies the game. After every Act you're treated to about a 30 minute television show that basically tells the story of the big evil corporation that's apparently behind time screwing up. It does feel a little weird to be playing an action game and then reaching the end of the Act (which usually ends with a big crescendo) only to then play a short section where you have to make a decision, which will then influence some plot points and the show you watch. Of course the hook of this is that your decisions affect what happens, but from what I can tell it's more akin to TellTale games "decisions" where there may be some differences in characters and settings, but the overall plot and major players are not affected. Whether or not the changes are significant enough to merit a second playthrough have yet to be determined (and unfortunately you can't play concurrent games.) To get back to the show itself, it's pretty good. The writing and style are VERY reminiscent of the old 24 show, so if you were into that you'll likely be into this.
Overall I am enjoying my time with Quantic Dream Quantum Break. I've been a fan of Remedy's story heavy games for a while and so far this one hasn't disappointed. The game has undeniably high production values and they're used quite well IMO. The gameplay would have greatly benefited from copying the Mass Effect 2 style of Gears of War with magic system as opposed to the floaty ME1 system to make for a truly satisfying experience, but Remedy games at their core have usually put plot/story over gameplay. I'm definitely interested to see where the plot ends up.
