Painkiller: Recurring Evil is the sixth installment of action-packed FPS, which was started by the Polish studio People Can Fly. However, it is not a full-fledged sequel, but a standalone expansion that introduces 5 new maps, one new weapon, a soundtrack and a new story. The gameplay mechanics themselves have remained unchanged - the player's task is still to eliminate hordes of enemies and reach the end of the level in one piece. His ability to transform into a demon after collecting the right amount of souls helps him to achieve success. The plot of Recurring Evil once again tells the story of Bill Sherman, the main character of the 2009 release of Painkiller: Resurrection. The action of the game takes us to purgatory, where once again we have to face the forces of evil in the fight for our own soul. The only way to do this is to break through dangerous and previously unexplored areas teeming with hellish creatures. Each of the five new locations was designed from scratch by the Russian studio MED-Art and they are characterized by great diversity. Battles take place in a gloomy abbey or a temple complex engulfed in the jungle, and soon after move to an old warehouse or a dilapidated highway, filled with the wreckage of abandoned cars. The game runs on the worn-out PainEngine engine - the same one on which the first part of the series was created. However, the graphics have been slightly improved, mainly due to the increase in texture resolution and detail with which individual models were made. The improvements have also affected the artificial intelligence of opponents, who in this installment play against the player in exceptional numbers - according to the developers, there are over 6 thousand of them. Painkiller: Recurring Evil is a production aimed mainly at fans of the series. The time it takes to complete the game is estimated to be about 5 hours.
