Rockstar is offering a free t-shirt to those who pre-order Grand Theft Auto V via its official shop.
The tee, which will only be offered in US via Rockstarwarehouse.com, is a light-blue colour with 'KIFFLOM' printed on the front in white, and the phrase 'The Tract is not yet Written' on the back.
'KIFFLOM' is a fictional religious cult within the GTA universe, and the subject of this GTA V viral site.
Rockstar says to "stay tuned" for news on any future promotions for Europe and other territories.
A GTA V release window of Spring 2013 has been confirmed.
