This game is very good autobattler where you're pushed into the shoes of a Gladiator Guild Manager. As such, you have to recruit, train and equip your team of gladiators through different means, you'll have a bunch of quests around three factions that'll reward you with different things.
You also clear different arena, once you beat one of them you'll unlock new units to change your strategy and adapt it you the ever changing group of ennemis.
In addition to the pretty good gameplay and gladiator management, the game has a fairly good sound design and is visually pleasant.
So if you like this sort of games, I think this one is probably one of the best of his genre.
