For those who don't want to unlock the content by playing the game.
Codemasters has released two DLC packs for DiRT 2, although neither actually adds any new content to the game.
Instead what we've got are two packs that unlock content that would otherwise be accessed through normal gameplay.
Trust Fund Pack - 400 MS Points
Instantly unlock 25 best-in-class World Tour vehicles, plus ten Easter egg secret vehicles, 93 liveries and every available upgrade at pro and all star level.
Access All Areas Pack - 400 MS Points
Unlock all 41 tracks playing host to 100 events. This includes entry into exclusive X-Games events in LA, London and Tokyo.
Just to be clear, all content made available via the purchase of these DLC packs can be unlocked through normal gameplay.
