4. Call of Duty: Black Ops Declassified
Easily the worst game in the entire Call of Duty lineage is Black Ops Declassified, the new title for the PSVita, a woeful distillation of everything that was great about the surprisingly unique Black Ops 2. It doesn't begin well; the classic Zombie Mode that has proven so enjoyable in the last few Call of Duty games is nowhere to be seen, all the more disappointing given that its casual nature is perfectly suited to mobile, breezy gaming. It gets worse, though, the single player offering doesn't have a single scrap of the ingenuity that the Black Ops 2 equivalent does, resulting in a boring, generic and overly brief campaign that's forgotten soon afterwards. Oh, and you can't save during missions - a bizarre choice that is forced upon the viewer for seemingly no reason at all. Even the multiplayer, the long-standing hallmark of the Call of Duty series, is resolutely dire, suffering from countless glitches and overly claustrophobic maps that don't allow the player much freedom. Easily the worst game in the series and a disgrace for handheld gamers everywhere.
