GladiuX, the successor to Gladiator Begins, is being developed by Acquire and Starcaster Games, and it is expected to come out in 2020
Well, if you happen to ask me "what is GladiuX?" my answers would fall pretty short. All I really know is that it is a successor to Acquire's Gladiator Begins and it uses Unreal Engine. GladiuX, the collaboration between Starcaster and Acquire has an official announcement section on Starcaster's website, but it contains little to no information about the title.
Starcaster might sound like a new developer at first, but they've actually been in the gaming industry for more than 28 years. Their work mostly contained helping out other developers but they have their own titles, such as So Many Me, too. And if you ask about Acquire, they did Tenchu -like c'mon man you should know them.
Starcaster has a teaser website for GladiuX that contains screenshots from the title. GladiuX is expected to come out in 2020 for PC and consoles. It's not certain yet if the title is going to be available on next-gen consoles.
