Valve has unveiled this week’s Steam Mid-Week Madness sale, taking 50% off PopCap’s excellent tower defense title Plants vs. Zombies, which now runs only $5 through Turkey Thursday, November 26.

The critically acclaimed game was already well worth the $10 packing five game modes, a 50 level campaign, over 25 types of zombies and a ton of replay value. $5 is a small price for a whole extra-long weekend’s worth of action strategy goodness.

Plants vs. Zombies released in May earlier this year.
