Rumour: Sly 4 Teased in The Sly Collection

BOOM widget 363244A new entry in Sucker Punch's platforming steal 'em up series Sly Cooper may be in the works, as one player of The Sly Collection claims to have discovered a trailer for the unannounced sequel Sly 4 in the recently-released revamp bundle.

Rumoured to be unlocked by obtaining all the trophies in The Sly Collection, the supposed trailer was captured by Youtube user 'tatermoog.' It shows Sly's silhouette peeking out at a patrolling guard and ends with a logo for 'Sly 4,' subtitled simply with a question mark.

Sly creator Sucker Punch has yet to announce a fourth game in the series, nor its next project after inFamous 2, which hits PlayStation 3 in 2011.

Shacknews has contacted Sucker Punch and long-time publishing partner Sony for comment. For now, watch the trailer below but do take it with a pinch of salt.
