XCOM: Enemy Within received generally positive reviews from critics. Ben Reeves of Game Informer lauded the game, advising that "anyone who loves an intense firefight should test their mettle on Enemy Within," although also noting that "Despite Firaxis’ improvements, the developer wasn’t able to fix the line-of-sight issues" of the main game and that "acquiring new squad members still feels unbalanced; since you can't assign your soldiers' roles, and they only learn their specialty once they've ranked up, it's easy to end up with holes in your squad".[8] Eurogamer's Stace Harman echoed similar statements, stating that despite its flaws, "Enemy Within is an improvement on an already excellent game, Destructoid's Chris Carter proffered similar praise, headlining his review with "It almost feels like a sequel."
