What Players Need First
Mechanicus II is not a generic Warhammer 40,000 page. It is a specific launch-week tactics game with specific user questions: which platform can play it, whether Necrons are playable, what PC specs are required, whether Steam Deck is a safe option, whether the Mixed review signal should change a buying decision, and which campaign is a better first fit.
