X-HERO is a superhero battler that became the most downloaded game on iOS in September (according to AppMagic). On September 30, he and his Android version of Epic Heroes disappeared from the App Store and Google Play.
Shortly before the removal, both projects encountered user dissatisfaction. Gamers wrote that when they tried to buy in-game items, money was debited from them, but the items themselves did not appear in the profile. The developers ignored requests for refunds.
Note that at the time of writing the news Epic Heroes is again available on Google Play. But X-HERO is still missing from the stores.
