Onslaught is by no means the definitive must own CoD DLC but it’s solid and gives Ghosts some more legs. So really what more could you ask for?

I was pleasantly surprised by Onslaught, especially considering the fact that Ghosts was so underwhelming. Although it won't do too much to change your mind if you're an adamant Call of Duty hater, the new Extinction episode is promising, and there are three solid maps here for the taking.

It's one of the brighter spots in this somewhat patchy DLC set, but serious online players needn't shrug off a welcome injection of variety. [April 2014, p.73]

With four new maps, a couple of weapons and an extra episode for the Extinction mode, the classic DLC formula of Onslaught is too expensive for what it offers, while the horror cameo by Michael Myers feels a bit cheap and tacky. Zombies, aliens and now serial killers: what’s next, CoD?

On balance, the new Extinction map is probably the best thing here: cohesive and rewarding, it's everything the main game isn't these days.

Same old story again. Three new maps, one remake and a new totally overpowered weapon for fifteen euros. Infinity Ward is doing terribly wrong with cod and this DLC did not fix any of the problems from the original game. Luckily Extinction saved it from a bad failure.

With only one really interesting map (4 are new in this DLC) and a satisfying new episode of the Extinction Mode, Onslaught is a mixed addition to the CoD Ghosts universe. Acceptable but not a must have.
