The concept art shows two figures wearing jumpsuits and gas masks getting out of the back of a van, and - as it is Grand Theft Auto - both figures are of course also carrying assault rifles.
Rockstar did not provide any context for the artwork, which may be depicting a mission from the upcoming game.
The studio also teased that there will be "lots of info coming next month" about Grand Theft Auto 5.
Announced last year, Grand Theft Auto 5 is thought to follow the exploits of lead character Albert De Silva, played by Ned Luke.
It was originally rumoured to have a release scheduled for this year, though more recent retailer listings have suggested it could arrive in March 2013.
Up until now Rockstar Games has remained tight-lipped, not confirming a release date or platforms for Grand Theft Auto 5. Presumably that will change next month when the studio reveals new details.
