Raunchy puzzler Catherine is one of the five games coming to Europe's PlayStation Plus next month. The not-so-sheepish Atlus game joins Malicious and the previously announced Hitman Absolution in the PS3's Instant Game Collection on May 1.

Meanwhile, Vita-owning subscribers can power up with a couple of shoot-em-ups. First up is the oddball steampunk of Sine Mora on May 8, and that's followed by Velocity Ultra on May 15. The Vita upgrade of Futurlab's Mini was penciled in for May in North America, so its arrival on PS Plus EU likely means it'll be released on PSN the same week.

As ever, newbies shooting up the place forces old stuff to scream in terror as it flees the service. F1 Race Stars, Okami HD, and Quantum Conundrum leave a collective puff of smoke on May 1, with Zero Escape: Virtue's Last Reward and Thomas Was Alone soon scampering after on May 8 and May 22 respectively.
