Let me explain those:
- SH(Soul Hunters-USA/EU), DotArena(SEA) and SC (Soul Clash-Japan/KR) were under Lilith Games in China （小冰冰传奇，formally as 刀塔传奇）
- DotArena is the first oversea publisher from Lilith Games(Under FunPlus)
- Soul Hunters were second but formally as Allstar Heroes (Under Allstar Games) before changed it to Soul Hunters (Publisher is Kick9 Inc before back to Lilith Games in USA)
- Soul Clash were third under GAEA Games (In Japanese and Korean Version)- but following Origins Version
- HC (Heroes Charge- under uCool ) is nothing but a thief / stolen content from Lilith Games. He also stole some of content from World of Warcraft, Clash of Clans, etc... and... He is the one behind Blizzard Case(Forced Lilith Games to changed most of hero design)
Hopefully this answers your problem.
