Dark Sector

Upon finding Mezner, Hayden becomes infected with the virus, which mutates his right arm, giving him new abilities such as invisibility, shields, and the use of a special knife-like weapon called the glaive. The infection also allows Hayden to use firearms like shotguns or pistols, taken from enemies or purchased from the Black Market.

Gameplay involves exploring the environment, fighting enemies, and completing objectives. Hayden can also upgrade his abilities and equipment using experience points and resources found throughout the game.
