This is a fun game that will especially appeal to fans of Tom Clancy's Rainbow Six Siege as it fuses familiar game mechanics with a new enemy. (Instead of Rainbow Six operatives, the soldiers in Tom Clancy's Rainbow Six Extraction are members of REACT, to ward off aliens, but you get the idea.) Unlike other Rainbow Six games which are grounded in realism, this sci-fi spin on the formula has a "fear factor," too with maps set in relatively tight quarters against a variety of aliens and hazards. For instance, a "screaming" Archaean will alert nearby nests to explode into additional threats you need to take care of. And the necessity to go back to rescue a downed teammate is exhilarating, to say the least. These hapless operatives are protected in a yellowish cocoon and set in part of an Archaean tree, which you need to rip them out of while it tries to suck him or her back in at the same time. This is one of the highlights of the game, because you'll need to keep an eye on incoming attacks from both the tree and other aliens while one of your teammates pulls out your MIA colleague.
The biggest issue, though, is the alien enemies aren't too smart, and there's no option for humans to control the aliens, which is a huge oversight. The objectives are also limited, and repetitive, which also hurts its replay factor. Still, it's a fun and frenetic co-op team shooter -- that delivers thrills, spills, and chills. Plus you can play on your own, if you like, but it's not as much fun. While it feels more like an expansion pack than a brand new game, the reasonable price point justifies the purchase for the several hours you'll no doubt be playing this with others online -- especially for fans of Rainbow Six Siege universe. It adds a fun supernatural twist to the tried-and-true shooter mechanics you might have been playing for years. Tom Clancy's Rainbow Six Extraction is a very good but not exceptional shooter, but expect it to get better over time as new modes, events, and weekly events will be added.
