www.sneakygames.com and www.arenaofheroes.com aren’t up and there last social media updates were from June. I see their last app was a F2P game for W8/iOS/Android called Glorious Maximus. I tried out their AoH turn-based MOBA a while ago and it was interesting but re-checking a bookmark seems to indicate that they’re now dead.
I know Zattikka PLC out of Britain bought them in 2012. That’s the last business-related news I heard about them.
Zattikka went belly up shortly after if I recall but their website and stuff had been working until this past weekend.
