BioShock Infinite will not offer a multiplayer element, series front-man Ken Levine has confirmed on Twitter.
Responding to a question regarding the inclusion of multiplayer, Levine wrote: "No multi."
That seems pretty clear cut.
Irrational was known to be working on two multiplayer modes – Spec Ops and a defense-style mode set in a steampunk arcade machine – but these were publicly cancelled back in August.
BioShock: Infinite is set for release on February 26, 2013.
