There are "secrets" over at Codemasters according to a new twitter tease from the studio, and this particular hush-hush topic is likely GRID related. The GRID twitter account has tweeted an image of a labelled door.
The world 'Playtest' is stamped on it followed by the caption "Shhhhh secrets". Codemasters is yet to announce future racing titles in the works but GRID seems like one. Call it a hunch.
GRID 2 released back in May last year for PC, Xbox 360 and PS3. It drew attention with its £125k special edition that included a GRID-themed BAC Mono supercar.
