Painkiller, a main game released in 2004, is a fast-paced Shooter incorporating Puzzle elements across platforms like PC and Xbox. You are trapped between Heaven and Hell, fighting hordes of monsters to earn purification. The core loop involves intense, arena-style combat using a varied arsenal, uniquely complemented by the ability to temporarily transform into a powerful, possessed creature to manage overwhelming enemy waves. The game features expansions and has received multiple remake versions over time.
The primary gameplay loop is defined by high-intensity, fast-paced combat against overwhelming numbers of enemies in contained environments. Players must utilize a diverse arsenal of weaponry to manage and eliminate these continuous waves of foes. Navigation through the often complex levels is critical, as the game integrates environmental challenges alongside the constant threat of attack.
A distinctive feature setting this title apart is the ability for the player character to temporarily morph into a possessed creature. This transformation grants significant, temporary power boosts, which are essential for surviving the most densely populated enemy encounters and managing the relentless pressure applied by the hordes.
While predominantly an action-focused shooter, the experience is augmented by the inclusion of Puzzle mechanics. Players are often required to interact with the environment or solve spatial challenges to progress through levels or unlock new areas, adding a layer of strategic thinking to the moment-to-moment combat.
As a core release, the game has been supported over time with one official expansion pack. Furthermore, the experience has been revisited through two separate remake versions released across its lifespan, offering updated graphical fidelity and potential mechanical refinements to the original concept.
The content of this game is suitable for persons aged 16 years and over only. It contains: Realistic looking violence.

Painkiller: Hell & Damnation is both remake and sequel of the first-person shooter video game Painkiller, developed by The Farm 51 and published by Nordic Games.

Battle never ceases in the realm known as Hell. This time around it's a battle for the freedom of your very soul. Will you be able to escape from the prison hidden in the darkest deepest chasm of Hell? Do you have enough courage to travel through the most dangerous and twisted areas which are infamous for their unsafety even among demons themselves? Are you prepared to significantly reduce the demonic population of these areas? Once again you'll have a chance to experience the magnificent dark atmosphere of the good (or evil?) Painkiller, the only true old-school First Person Shoot, tough as nails, without a trace of remorse, without a glimpse of motion blur or other technological makeup. Just Painkiller and nothing else matters.

Painkiller – Redemption continues the story of Daniel and Belial as they joined forces for the first time to end the bloody conflict between heaven and hell. You will discover all new maps, fight off literally thousands of demonic fiends, and lose yourself in the intense gameplay rounded off with an absorbing heavy metalsoundtrack. The newest addon brings the Painkiller franchise back to its roots. Breathtaking action, thousands of monsters and exotic weapons are a solid foundation for a Painkiller game. The game also features a tactical component; while reaching your objectives in each level, you unlock Tarot Cards, which will soon prove to be very helpful. In additional to that, collecting souls of fallen enemies will temporarily transform you into a mighty demon.

Painkiller: Purgatory HD is an Android/iOS remake of 2004's classic PC horror game Painkiller.

The game's basic gameplay is the same as the original Painkiller. The player has to face off numerous enemies and defeats them, moving from one location to another. All the weapons have alternative fire regimes. While the majority of enemies and all original weapons are presented, the game features some new additional gameplay elements not seen in original or its other expansions.

Painkiller: Overdose is the second stand-alone Painkiller game. The story is set just after Daniel kills Lucifer. The death of Hell's leader allows Belial, the prisoner and outcast, to escape and start his vendetta against those who imprisoned him: demonic beast Cerberus and Sammael, an angel who betrayed his own kind. Belial starts his journey with killing his prison warden (and later using his head as a weapon). After traveling through various hellish places and defeating countless demons he kills Cerberus and reaches Samael's lair. There, Belial defeats the fallen angel and rips his wings off as an act of vengeance.
