Blacklight: Retribution is a futuristic first-person shooter, a sequel to Blacklight: Tango Down. It was developed by Zombie Studios and published by Perfect World. The focus is on a highly customizable character and weapon system that unlocks upgrades one at a time as players level up. It is based on a free-to-play business model. Despite being free, it is not "pay 2 win", as almost all weapons can be permanently bought with in-game currency that is earned by playing. Real money is mostly used for creating an individual look, though it will also unlock items regardless of the player's level, thus saving time, but not overpowering a player forever. The game was released on April 3, 2012. On July 2, 2012, it was also made available on the distribution platform Steam. New content is being released for the game on a regular basis. The game can currently be played in English, French and German.
