Catherine has "topless female demons"

Risqué adventure game Catherine has "topless female demons" and colourful "demon bride" and "chainsaw-wielding baby" bosses.

That's why America's omni-parent, the ESRB, has rated the game M for Mature. Blood, Partial Nudity, Sexual Themes, Strong Language and Use of Alcohol and Violence are all present.

Most themes are explored by hero Vincent during dreams; nightmares he navigates hoping to reach the exit. Put a foot wrong and you'll be killed with "exaggerated splashes of blood". You'll be "stabbed, crushed, shot or bitten".

Vincent speeds up when plied with alcohol, although after more than three drinks he starts to stumble. Voice overs accompany this: "It's said that chugging alcohol isn't good for you, but sometimes it's necessary."

Sex and sexuality are "frequently referenced" - "I finally became a man! Got rid of my V-card, BOOM" - often while two characters share a bed.

"Another scene briefly depicts a woman caressing her body while making suggestive comments," the ESRB revealed: "'I've got such a hunger for these feelings. I know you have some hungers as well, don't you?'"

Swear words "f**k" and "sh*t" are heard.

Catherine still has no scheduled UK release. The game will appear in July across the US, however, and PS3 titles are region-free, so import away. And you may to: Eurogamer has heard good things about Catherine.
