Infinity Ward may have created Call of Duty but publisher Activision has always wanted to take the hit war-game series into different directions. Most of those efforts stalled—like the third-person variant that dev studio Sledgehammer was working on—and the public never gets to see what might have been.

But what you're seeing above is animation for a Call of Duty Tactics game that was in development at Vicarious Visions. It's listed as a prototype for Xbox 360 and PS3 on the website of animator Steve Nelson, who formerly worked at the studio that also made Marvel Ultimate Alliance 2 for Activision.

While praised for its frenetically fast-paced action, Call of Duty often gets criticized for its shallow strategic depth. It would've been interesting to see what a tactically focused spin-off of the first-person franchise would have played like. But that may not be happening anytime soon.
