Gloomgrave combines elements of a roguelike and a walker. The player finds himself in ancient locations where he must find powerful artifacts and rare relics. To complete the mission, he must interact with the environment and survive in a dangerous environment. As he progresses, the central character will upgrade his equipment and gain access to new builds that open up more abilities and skills to achieve the goal.

The combat system is presented in a turn-based style, giving the opportunity to calculate your own actions without rushing. Each playthrough creates an original dungeon that will never be the same. Random generation also applies to the location of enemies and bosses, traps and dropped items. There are over 50 items to loot, divided into types such as magic scrolls, armor, weapons, potions and skills.

On the way, the gamer will encounter 15+ types of monsters, each of which has different talents, strengths and weaknesses. The ward has more than 13 skills that help in battles or when overcoming traps. Before the start of the gameplay, the user needs to choose a character class, which changes the starting and pumped skills, appearance and style of passage. 9 different dungeons are distributed by difficulty level.
