BioShock 2 shipped without proper widescreen monitor support. The game would simply slap a letterbox on the 4:3 display, limiting the player's field of view. Fortunately, a patch released today adds 16:9 and 16:10 resolution support to the game's repertoire, meaning you'll finally be able to see that Splicer that's been creeping alongside you for the past few days.
The patch also fixes an issue in which "holding the M1 button would not register in Multiplayer gameplay," which sounds equally serious. Those are the only two fixes in the available update; however, 2K community manager Elizabeth Tobey promises "a larger, more extensive patch" is currently in the works.
