Steam's Midweek Madness sale takes a turn for the macabre this week with PopCap's lovely lawn defense Plants vs. Zombies available for a mere $5 until tomorrow.
Shack PSA: Plants vs. Zombies for $5 on Steam
Plants vs. Zombies became the prolific PopCap's fastest-selling game when it was released in May with a cheery fun take on the tower defense genre and walking dead. A demo is available on FileShack if you require a taste of the digital drug first.
An Xbox Live Arcade release is also in the works, arriving at a time unknown. An iPhone and iPod Touch version is also due "around the end of this year."
