The malignant majesty of Demon's Souls becomes free to North American PlayStation Plus members in today's PSN update. The servers for From Software action-RPG are staying online for the foreseeable future, so there's no reason to pass on a PS3 game we described as a "leather-clad mistress" in our 2009 review - unless, perhaps... you're scared?

Less sadistic Plus entries coming this month include Zombie Tycoon 2, which comes to PS3 and Vita via PSN on April 30, Malicious and Labyrinth Legends for PS3, and PSP game Soulcalibur: Broken Destiny for Vita. There are no PS Plus ETAs for those last three.

As ever, new stuff coming in pushes old stuff back out. If you want to grab Spec Ops: The Line from PS Plus, today's your last chance to do so. Street Fighter 4: Arcade Edition dragon punches out on April 9, while Anomaly: Warzone Earth flees on April 16.

Finally, today's PSN update brings discounts to The Walking Dead, Rainbow Moon, and the Söldner-X series, including the first season of Telltale's zombified adventure for $14.99, a price that drops to $10.49 with Plus. For all those deals, check out the PlayStation Blog.
