Gears of War 4 is certainly not innovative. It takes what has always worked and been enjoyable and gives you more.
Halo 5: Guardians is a return to form and a worthy entry in the franchise with new mechanics that breathe new life into the gameplay.
Halo 4 is a solid shooter but is easily one of the weakest entries in the series.
Battle Garegga is relentless, unforgiving, and rewarding all at the same time. You can definitely chalk it up as another fantastic M2 port.
