I remember working tirelessly to unlock Rayne (from BloodRayne) and members of Slipknot as playable characters just to do the same horde mode game over and over, and for some reason I don't remember ever getting sick of it. This game was sort of like a nu-metal version of EDF but with zombies, and definitely lead into my current joy of the EDF series to date. Would absolutely love to share even one or two missions of this game with friends, and replay Infected to re-experience the metalcore joy.
