Call of Duty isn’t a series known for changing things up much. After Advanced Warfare introduced wall-running and more dynamic aerial maneuvers, all of the other Call of Duty titles pretty much followed suit afterward. Last year’s WWII was obviously a step back into the trenches, and with Black Ops 4 on the horizon, fans were wondering how the gameplay would change for this new iteration.

If you’re joining from Treyarch’s last game, Black Ops 3, then yeah, there’s a fair few new features to get to grips with – the lack of a double jump just being the first of many. Though that’s not to say it’s a bad thing – Call of Duty: Black Ops 4 feels more like a Call of Duty game of yesteryear, with enough new features to make it a unique step forward for the series.
