All Game Guide Review by Scott Alan Marriott. "Hidden Invasion tries to tie together The X-Files with something along the lines of Red Dawn but ends up being yet another boring 3D beat-'em-up that offers nothing new to the genre and everything wrong with it." http://www.allgame.com/cg/agg.dll?p=agg&SQL=GRH||||35578

Cheat Code Central Includes instructions for entering hidden modes, and Game Shark codes. http://www.cheatcc.com/psx2/hi.html

Eurogamer Reviewed by Kristan Reed. "A better than average platformer with cleverly interspersed mini games to present the illusion of expansiveness and freedom." Score: 7 out of 10. http://www.eurogamer.net/article.php?article_id=4083
