A shooter based on a beloved strategy franchise? It’s the kind of idea that makes strategy fans nervous, but games like Command & Conquer: Renegade have proven that the possibility isn’t meritless. The Bureau: XCOM Declassified is not a great argument for an XCOM spin-off, however. It often puts its best foot forward, but while The Bureau mimics some of its inspiration’s touchstones, it doesn’t re-create their impact. The result is a third-person cover shooter that is decent fun but ultimately rings hollow.

What the Bureau nails is its retro-futuristic atmosphere, which channels an early-1960s view of the world straight from a Sears, Roebuck & Co. catalog. Protagonist William Carter looks as if he leapt from a postcard or periodical advert from the era: his hair is shellacked to perfection, and a heavy turtleneck sets off his freshly shaven face. Environments look slightly yellowed in the way we often imagine the 1960s, given how photographs fade over time. Sectoids–alien mainstays in the XCOM universe–have the big bulbous heads and skeletal bodies of the extraterrestrials you might have seen described in Amazing Stories magazine. This was the era of famous alien abductees Betty and Barney Hill, whose descriptions of bald-headed, gray-skinned invaders fueled generations’ worth of pop-culture depictions of men from outer space. The Bureau looks like a Hill hypnosis session come to life.
