Beneath Oresa combines 3 different genres. It's a mixture of a fighting game, a lightweight roguelike, and a collectible card game. This indie project has 3D graphics. The video game uses cel-shading technology. The video game has a medieval fantasy setting with steampunk elements. The player travels through the depths that are located under the city abandoned by the gods. The gamer fights in tactical arenas with ordinary opponents and leaders, receives artifacts, and also gradually strengthens his deck and creates a character build to suit his playing style. Contractions take place step by step. Cards allow you to change positions on the battlefield, pit opponents against each other, deliver different blows, block or parry different attacks, perform super attacks, and so on.

In the game Under Oresoy you need to choose not only a fighter, but also a companion. All 9 heroes differ in appearance and special abilities. They also belong to three different factions. When the user has decided on the protagonist, he must choose one of the 8 remaining fighters to play the role of a partner. Each warrior and warrior acquires unique skills when they become assistants and assistants. For example: one companion shows himself effectively in battles with bosses, while another can give additional upgrades to cards. During upgrades, the player is always offered a choice of 2 options. For example, he can make the skill deal less damage, but do it throughout the entire battle. Or the effect can become much stronger, but it will only last until the end of the turn.
