In Hidden Invasion 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, the game 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 cut-scenes continually develop the plot. The levels are also totally interactive, so players can utilise the scenery as an additional weapon, collapsing ledges onto advancing foes while taking short cuts to evade pursuit and double back to catch your enemies unaware.
