Neon Struct [official site] is one of the 25 best stealth games on PC, says our Adam, and who am I to disagree with him? Him with his gentle voice and wry smile. And, uh, apparently his sneaking skills good enough to write that previous sentence when I popped into the kitchen for a cuppa. Well, no matter. Point is: Neon Struct was already grand, and now it’s practically endless, as it has a level editor with Steam Workshop support. Minor Key Games have also dropped a free expansion. How splendid!
