Declassified, in its general handling at least, does a semi-decent impression of Call of Duty. It’s fast, fluid and works in the way that you should hope, and the button layout will be familiar to most.
It’s at least truer to CoD than Burning Skies was to the Resistance franchise. To that end, Declassified does provide a decent early impression, but when you spend some extended time with the game, the problems start to come to light.
For starters, there are some Vita-specific control features, but they add nothing to gameplay. The best implementation is in tapping anywhere on the touchscreen to mêlée; it’s simple and doesn’t take too much time. To throw grenades, you have two options; tap the on-screen button to lob one where you’re aiming, or much like Burning Skies, you can drag the grenade icon to where you want to throw it. This is an annoying process, and it leaves you shifting your hand in the middle of a firefight.
