Aliens: Fireteam Elite is a fine game for spending a weekend with friends, but like any co-op shooter, it's less fun when played solo.
I recommend: Aliens – Fireteam Elite
Elite is set in the Alien universe, 22 years after the events of Alien 3. You are a member of a three-man unit of Colonial Marines assigned to investigate a distress call from a destroyed refinery station.
Of course, this being the series, it means someone's gone and gotten their hands on the Xenomorphs, and before you know it you're hip-deep in raging, acid-fueled killing machines.
You can play Fireteam Elite solo with a team of two AI partners—fittingly, they’re android “synths,” making them literal bots—but I didn’t have much fun there. It’s an intense, strategic third-person shoot-’em-up that encourages you to watch each other’s backs, keep each other alive, and rack up a high alien body count. Bring friends, or don’t play at all.
