New weapons and abilities open routes through the underground facility in Shadow Complex, a side-scrolling action-adventure. Players fight enemies and revisit previously inaccessible areas within an interconnected complex. The environments are rendered in three dimensions, while movement stays on a two-dimensional plane. An experience system rewards exploration and combat with upgrades that carry into new playthroughs.
Jason Fleming discovers the facility while searching for his girlfriend, Claire, during a mountain backpacking trip. Its operators, the paramilitary Progressive Restoration, are preparing coordinated attacks across the United States. Jason must rescue Claire and uncover the group's plans.
