A spearhead alien invasion fleet is expanding its occupancy of Earth with the help of traitorous government officials. Assuming the role of a hard-bitten special forces agent, the player embarks on a death-or-glory mission to blow the lid off the conspiracy and thwart the alien takeover.
Through fighting, exploration, and puzzle elements, Hidden Invasion weaves a mixture of incredible graphics and engaging gameplay to provide dazzling action set within a lavishly illustrated 3-D environment. Motion-captured characters move realistically through intricately designed sets, while a series of animated cutscenes continually develop the plot. The levels are also totally interactive, so players can utilize the scenery as an additional weapon, collapsing ledges onto advancing foes while taking shortcuts to evade pursuit and double back to catch your enemies unawares.
