In the world of PC gaming, a "repack" refers to a compressed, re-encoded version of a game distributed by scene groups. These groups take the original retail files, remove redundant localizations, compress audio/textures losslessly (or near-losslessly), and often crack the DRM to allow offline play.
The game is a wave-based, third-person shooter that heavily emphasizes character progression and mature themes. Lust n Dead-Repack
