Sledgehammer Games' Glen Schofield has taken to Twitter to ask Call of Duty fans to support Call of Duty: Modern Warfare 3 on Metacritic.

"I don't usually do this but, if u like MW3 go 2 Metacritic.com & help our user score," writes Schofield. "It's suspiciously low. Be honest but help if u agree."Modern Warfare 3 is attracting a torrent of user scores of zero across all three platforms. The current user score (out of 10) is 2.7 on Xbox 360 2.0 on PS3 and 1.5 on PC
