Above average shooter. It didn't feel like a straight up linear shoot 'em fest a la Halo. But it didn't stick out anymore than any other FPS on the market today. The addition of the O.W.L. was a great tool that utilized the new touch pad on the PS4 controller.
The plot was interesting, especially if you've followed along the prior storylines. A nice twist also. But at the end of the day, it lacked a sort of... substance. Didn't feel as though the character - Kellen - was developed enough.
The graphics were AMAZING. Truly next-gen graphics and sound and a fine example of what is to come for the PS4. The screenshots taken on my system were absolutely breath taking.
Definitely worth the money to buy, however when you're done with the campaign don't bother with the multiplayer. Trade it in and get something else after you get your trophies.
