OXM: "Sanctum 2 does lack refinement in some ways, though. The in-game visuals are a bit rugged, plus the comic book–style loading-screen story sequences lack intrigue. An even bigger concern is some environmental glitches: a couple of times, we were knocked back into areas that we couldn’t escape from without triggering suicide. While the game feels rough around the edges, the core is so entertaining that such flaws don’t dominate the experience. Whether you play solo or with pals, solving Sanctum 2’s many challenges proves deeply absorbing."
